WARNING!
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD
TO OBTAIN POSITION INFORMATION.
CAUTION
When showing navigation data to a position (waypoint), a GPS unit will show
the shortest, most direct path to the waypoint. It provides navigation data to the
waypoint regardless of obstructions. Therefore, the prudent navigator will not
only take advantage of all available navigation tools when traveling to a way-
point, but will also visually check to make sure a clear, safe path to the waypoint
is always available.
WARNING!
When a GPS unit is used in a vehicle, the vehicle operator is solely re-
sponsible for operating the vehicle in a safe manner. Vehicle operators
must maintain full surveillance of all pertinent driving, boating or fly-
ing conditions at all times. An accident or collision resulting in damage
to property, personal injury or death could occur if the operator of a
GPS-equipped vehicle fails to pay full attention to travel conditions and
vehicle operation while the vehicle is in motion.

Section 1: Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of digital sonar and GPS! We know
you're anxious to begin navigating and finding fish, but we have a favor
to ask. Before you grab the unit and begin installing it, please give us a
moment or two to explain how our manual can help you get the best
performance from your compact, wide-screen, combination fish finder
and mapping GPS receiver.
First, we want to thank you for buying a Lowrance sonar/GPS unit.
Whether you're a first time user or a professional fisherman, you'll dis-
cover that your unit is easy to use, yet capable of handling demanding
navigation and sonar tasks. When you team your unit with our custom
mapping software MapCreate 6, you have an incredible combination.
You won't find another combination GPS and sonar unit with this much
power and this many features for this price!
Our goal for this book is to get you on the water fast, with a minimum
of fuss. Like you, we'd rather spend more time boating or fishing and
less time reading the manual!
So, we designed our book so that you don't have to read the whole thing
from front to back for the information you want. At the start (or end) of
each segment, we'll tell you what content is coming up next. If it's a
concept you're already familiar with, we'll show you how and where to
skip ahead for the next important topic. We've also made it easy to look
up any tips you may need from time to time.
The manual is organized into 10 sections. This first section is an intro-
duction to the LMS-334 iGPS and LMS-339cDF iGPS sonar and GPS. It
tells you the basics you need to know before you can make the unit look
around and tell you where you are, or look below the surface to find
some fish.
Section 2 will help you install your unit and the transducer. We'll show
you how to get the MultiMedia Card (MMC) correctly installed inside
the unit. We'll also tell you about some of the available accessories.
Section 3 covers Basic Sonar Operation. It will show you how easy it is
to run your sonar, right out of the box. This section features a one-page
Sonar Quick Reference. (If you've already jumped ahead and fig-
ured out how to install the unit yourself, and you just can't wait
any longer, turn to the Quick Reference on page 49 and head
for the water!)

After you've gained some experience with your sonar, you'll want to
check out Section 4, which discusses more advanced Sonar Options and
Other Features.
When you come to a sonar menu command on your unit’s screen, you can
look it up in the manual by skimming over the table of contents, just flip-
ping through Section 3 or scanning through the sonar options in Section 4.
If you're having difficulty with your sonar, you can find an answer to
the most common problems in Section 5, Sonar Troubleshooting.
The manual switches from sonar to navigation in Section 6, which in-
troduces you to Basic GPS Operations. This section features a one-
page GPS Quick Reference on page 108.
Section 6 contains short, easy-to-scan GPS lessons that follow one an-
other in chronological order. They're all you'll need to know to find your
way on the water quickly.
After you've learned the basics (or if you already have some GPS expe-
rience), you may want to try out some of the unit’s many advanced
navigation features. That brings us to Section 7, Advanced GPS Opera-
tions. This section contains the rest of your unit’s GPS command func-
tions, organized in alphabetical order.
When you come to a GPS menu command on the screen, look it up in
the manual by skimming the table of contents, flipping through Section
6 or scanning through the command portion of Section 7.
Your unit is ready to use right out of the box, but you can fine tune and
customize it's operation with dozens of options. Since sonar is the unit's
key feature, we put the main sonar options in Section 4. Some options,
such as screen brightness settings, affect both sonar and GPS opera-
tions. We describe how to use those common options along with GPS
options in Section 8, System Setup and GPS Setup Options. Section 8 is
organized in alphabetical order.
In Section 9, we go into more detail on one of the unit’s most remarkable
GPS capabilities — Searching. We'll introduce a search example in the Ba-
sic GPS Operation section, but there are so many map items you can
search for, we had to give this function it's own section in the manual! For
example, did you know your unit can look up business phone numbers,
functioning as a virtual Yellow Pages? We’ll show you how in Section 9.
Finally, in Section 10, we offer Supplemental Material, including a list
of the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on
specifications to see just how much sonar and GPS power your unit con-

tains. It's important to us (and our power users), but, if you don't care
how many watts of power the unit has, or how many waypoints the your
unit can store, skip ahead to important information on how the sonar
works, on page 5. (Background on GPS begins on page 6.)

Service Department; phone numbers are listed on the last page.
How Lowrance Sonar Works
Sonar has been around since the 1940s, so if you already know how it
works, skip down to read about the relatively new technology of GPS.
But, if you've never owned a sonar fish finder, this segment will tell you
the under water basics.
Sonar is an abbreviation for SOund NAvigation and Ranging, a tech-
nology developed during World War II for tracking enemy submarines.

(Lowrance developed the world's first transistorized sportfishing sonar
in 1957.) A sonar consists of a transmitter, transducer, receiver and
display. In simple terms, here's how it finds the bottom, or the fish:
The transmitter emits an electrical impulse, which the transducer con-
verts into a sound wave and sends into the water. (The sound frequency
can't be heard by humans or fish.) The sound wave strikes an object
(fish, structure, bottom) and bounces back to the transducer, which
converts the sound back into an electrical signal.
The receiver amplifies this return signal, or echo, and sends it to the
display, where an image of the object appears on the scrolling sonar
chart. The sonar's microprocessor calculates the time lapse between the
transmitted signal and echo return to determine the distance to the
object. The whole process repeats itself several times each second.
Your unit can record a log of the sonar signals that scroll across the
screen and save them to the MMC memory card. (These recordings are
also called sonar charts or sonar graphs.) You can replay this sonar log
in the unit using the Sonar Simulator function, or play it back on a per-
sonal computer using our free Sonar Viewer. The viewer is available for
download from the Lowrance web site, www.lowrance.com.
You can save several different sonar log files, erase 'em and record new
ones, over and over again. The size of your sonar recordings is only
limited by the free space available on your MMC.
How Lowrance GPS Works
You'll navigate faster and easier if you understand how your unit scans
the sky to tell you where you are on the earth — and, where you're go-
ing. (But if you already have a working understanding of GPS receivers
and the GPS navigation system, skip ahead to Section 2, Installation &
Accessories on page 13. If you're new to GPS, read on, and you can later
impress your friends with your new-found knowledge.)
First, think of your unit as a small but powerful computer. (But don't
worry — we made the unit easy to use, so you don't need to be a com-
puter expert to find your way!) It includes a keypad and a screen with
menus so you can tell it what to do. The screen also lets the unit show
your location on a moving map, as well as point the way to your desti-
nation.
This gimbal-mounted unit uses an internal antenna and receiver,
which makes the whole system work something like your car radio. But
instead of your favorite dance tunes, this receiver tunes in to a couple of
dozen GPS satellites circling the earth. Your unit listens to signals from
6

as many satellites as it can "see" above the horizon, eliminates the
weakest signals, then computes its location in relation to those satel-
lites. Once the unit figures its latitude and longitude, it plots that posi-
tion on the moving map shown on the screen. The whole process takes
place several times a second!
The performance doesn't stop there. Stored in the permanent memory
of each unit is a basic background map of the entire world. We lock it in
here at the factory — you can't change or erase this map.
The background map is suitable for many navigation chores, but for
maximum accuracy and much more detail, you need our optional map-
making software, MapCreate 6. Some unit features — such as
searching for businesses and addresses — won't work without a custom
MapCreate map. There is so much detail in our background map (and
even more in MapCreate) that we'll describe their contents and differ-
ences in Section 6, Basic GPS Operations, on page 95.
Another portion of the unit’s onboard memory is devoted to recording
GPS navigation information, which includes waypoints, event marker
icons, trails and routes. This lets you look back the way you came.
Think of this data storage like the hard drive memory in a computer or
a tape in a cassette tape recorder. You can save several different GPS
data files, erase 'em and record new ones, over and over again. These
GPS Data Files (file format *.usr) can be shared between, not only the
LMS-334c iGPS and LMS-339cDF iGPS, but other Lowrance GPS units
and even personal computers.
Your unit has one more thing in common with a personal computer.
Just as computers have a floppy disk drive for storing and exchanging
files, the unit has a slot for an MMC (MultiMedia Card) or SD card (Se-
cure Digital card) flash memory card. These solid-state memory devices
are about the size of a postage stamp, but can hold data ranging from 8
MB to 2 GB. (Compare that to a floppy disk's 1.44 MB capacity!) Your
unit uses all that MMC space for two key GPS purposes. (The MMC is
also used to record sonar logs.)
First, you can backup your onboard GPS Data Files by copying them to
the MMC. Since the MMC is MMCs, if you don't have a computer.) Our
MapCreate mapping software can save, edit or create its own GPS Data
Files, which can be copied to the MMC and then loaded from the MMC
into unit’s memory. (NOTE: No matter where they come from, GPS Data
Files must be loaded from the MMC into memory before your unit can
use them.)
The other key GPS use for MMCs is storage of special high-detail, cus-
tom maps, which you can produce on your computer with our MapCre-
7

ate software. These MapCreate custom maps contain much greater de-
tail than the basic background map. These Custom Map Files (file
format *.lcm) not only may be shared between the LMS-334c iGPS and
339cDF iGPS, but also with other Lowrance GPS and sonar/GPS units
as well as personal computers. (For example, the exact same MMC,
custom map files and GPS data files can be used interchangeably be-
tween your gimbal-mounted unit and the hand-held iFINDER GPS
receiver.)
Your unit automatically reads Custom removable (like a floppy disk or a
cassette tape), you can store these GPS Data Files on a personal com-
puter equipped with an MMC card reader. (Or store them on a pocketful
of Map Files directly from the MMC or SD card. To use a custom map,
all you need to do is slide an MMC containing a map into the unit.
Introduction to GPS and WAAS
Well, now you know the basics of how your unit does its work. You
might be ready to jump ahead to Section 2, Installation & Accessories,
on page 13, so you can mount your unit and plug in the power. Or you
might want to see how our text formatting makes the manual tutorials
easy to skim. If that's the case, move on to "How to Use This Manual"
on page 11. But, if you want to understand the current state of satellite
navigation, look over this segment describing how GPS and its new
companion WAAS work together to get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by
the United States Department of Defense. It was designed as a 24-
hour-a-day, 365-days-a-year, all weather global navigation system for
the armed forces of the U.S. and its allies. Civilian use was also avail-
able at first, but it was less accurate because the military scrambled
the signal somewhat, using a process called Selective Availability (SA.)
GPS proved so useful for civilian navigation that the federal govern-
ment discontinued SA on May 2, 2000, after the military developed
other methods to deny GPS service to enemy forces. Reliable accuracy
for civilian users jumped from 100 meters (330 feet) under SA to the
present level of 10 to 20 meters (about 30 to 60 feet.)
Twenty-four satellites orbit 10,900 nautical miles above the Earth,
passing overhead twice daily. A series of ground stations (with precisely
surveyed locations) controls the satellites and monitors their exact loca-
tions in the sky. Each satellite broadcasts a low-power signal that iden-
tifies the satellite and its position above the earth.

Three of these satellites are spares, unused until needed. The rest vir-
tually guarantee that at least four satellites are in view nearly any-
where on Earth at all times. The system requires signal reception from
three satellites in order to determine a position. This is called a 2D fix.
It takes four satellites to determine both position and elevation (your
height above sea level — also called altitude.) This is called a 3D fix.
A minimum of three satellites are required to determine a 2D fix.
Remember, the unit must have a clear view of the satellites in order to
receive their signals. Unlike radio or television signals, GPS works at
very high frequencies. These signals can be easily blocked by trees,
buildings, an automobile roof, even your body.
Like most GPS receivers, the unit doesn’t have a compass or any other
navigation aid built inside. It relies solely on the signals from the sat-
ellites to calculate a position. Speed, direction of travel, and distance
are all calculated from position information. Therefore, in order it to
determine direction of travel, you must be moving and the faster, the
better. This is not to say that it won’t work at walking or trolling
speeds — it will. There will be more "wandering" of the data shown on
the display.
GPS alone is accurate for route navigation, but the U.S. Federal Avia-
tion Administration has special aircraft navigation needs that go be-
yond basic GPS. So, the FAA has developed a program to boost GPS
performance with its Wide Area Augmentation System, or WAAS. The
FAA commissioned the system on July 11, 2003.
WAAS is designed to increase GPS accuracy to within 7.6 meters verti-
cally and horizontally, but it consistently delivers accuracies within 1-2
meters horizontal and 2-3 meters vertical, according to the FAA. It does

this by broadcasting correction signals on GPS frequencies. Your unit
automatically receives both GPS and WAAS signals.
However, there are some fringe areas of the U.S., including parts of
Alaska, that do not yet receive robust WAAS coverage. Continued
WAAS development is planned to extend WAAS coverage in the years
to come.
WAAS boosts the accuracy of land GPS navigation, but the system is
designed for aircraft. The satellites are in a fixed orbit around the
Equator, so they appear very low in the sky to someone on the ground
in North America. Aircraft and vessels on open water can get consis-
tently good WAAS reception, but terrain, foliage or even large man-
made structures can sometimes block the WAAS signal from ground
receivers.
You'll find that using your GPS receiver is both easy and amazingly
accurate. It’s easily the most accurate method of electronic navigation
available to the general public today. Remember, however, that this
receiver is only a tool. Always have another method of navigation avail-
able, such as a map or chart and a compass.
Also remember that this unit will always show navigation information
in the shortest line from your present position to a waypoint, regardless
of terrain! It only calculates position, it can’t know what’s between you
and your destination, for example. It’s up to you to safely navigate
around obstacles, no matter how you’re using this product.

How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow
"keystrokes" appear as boldface type. So, if you're in a real hurry (or
just need a reminder), you can skim the instructions and pick out what
menu command to use by finding the boldface command text. The fol-
lowing paragraphs explain how to interpret the text formatting for
those commands and other instructions:

Arrow Keys
The arrow keys control the movement of dotted cross-hair lines on your
mapping screen called the cursor. The arrow keys also control a hori-
zontal line depth cursor on the sonar screen. The arrow keys help you
move around the menus so you can execute different commands. They
are represented by symbols like these, which denote the down arrow
key, the up arrow, the left arrow and the right arrow: ↓ ↑, ← →.
Keyboard
The other keys perform a variety of functions. When the text refers to a
key to press, the key is shown in bold, sans serif type. For example, the
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU.
Menu Commands
A menu command or a menu option will appear in small capital letters,
in a bold sans serif type like this: ROUTE PLANNING. These indicate that
you are to select this command or option from a menu or take an action
of some kind with the menu item. Text that you may need to enter or file
names you need to select are show in italic type, such as trail name.
Instructions = Menu Sequences
Most functions you perform with your unit are described as a sequence
of key strokes and selecting menu commands. We've written them in a
condensed manner for quick and easy reading.
For example, instructions for navigating a trail would look like this:
1. From the Map Page, press MENU|MENU|↓ to MY TRAILS|ENT.
2. Press ↓ to Trail 1|ENT|→|↓ to NAVIGATE|ENT.
3. You are asked to wait while it converts the trail into a route.
4. The wait message disappears and the unit begins showing
navigation information along the trail..
Translated into complete English, step 1 above would mean: "Start on
the Map Page. Press the Menu key twice. Next, repeatedly press (or
press and hold) the down arrow key to scroll down the menu and select
(highlight) the My Trails menu command. Finally, press the Enter
key."
Step 2 would mean: "Press the down arrow key repeatedly to scroll to
the trail named Trail 1, and press Enter. Next, press the right arrow
key and then the down arrow key to highlight the Navigate command,
then press Enter."

Section 2: Installation
Preparations
You can install the unit in some other order if you prefer, but we rec-
ommend this installation sequence:
Caution:
You should read over this entire installation section before drill-
ing any holes in your vessel!
1. Determine the approximate location for the unit, so you can plan how
and where to route the cables for the transducer, any sensor and power.
This will help you make sure you have enough cable length for the de-
sired configuration.
NOTE:
The GPS antenna is inside the unit, so you must mount the unit in
a location with an unobstructed view of the sky.
2. Determine the approximate location for the transducer, any sensor
and their cable routes.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the transducer and route the transducer cable to the sonar
unit. Install the speed or temp sensor, if applicable, and route the cable
to the unit.
5. Route the power cable from the unit's location to an appropriate
power source and connect it there.
6. Connect the transducer/power cable (and any sensor cables) to the
unit and mount the unit on the bracket.
Transducer Installation
These instructions will help you install your Skimmer transducer on a
transom, on a trolling motor or inside a hull. These instructions cover
both single- and dual-frequency Skimmer transducers. Please read all
instructions before proceeding with any installation.
The smaller single-frequency Skimmers typically use a one-piece,
stainless steel mounting bracket. The larger dual-frequency Skimmers
typically use a two-piece, plastic mounting bracket. The optional troll-
ing motor mount uses a one-piece plastic bracket with an adjustable
strap.
These are all "kick-up" mounting brackets. They help prevent damage if
the transducer strikes an object while the boat is moving. If the trans-
13

ducer does "kick-up," the bracket can easily be pushed back into place
without tools.
Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat. Use
extreme care if mounting the transducer inside the hull, because once
the epoxy is applied and it is set into position, the transducer cannot be
removed. Remember, transducer location is the most critical part
of a sonar installation.
Recommended Tools and Supplies
If you prefer the option of routing the cable through the transom, you
will need a 1" (25.4 mm) drill bit. A transom mount requires use of a
high quality, marine grade above- or below-waterline sealant/adhesive
compound.
NOTE:
The following installation types also call for these recommended
tools and required supplies (supplies are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: high quality, marine grade above- or below-
waterline sealant/adhesive compound.
Dual-frequency transom installations
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood
screws, high quality, marine grade above- or below-waterline seal-
ant/adhesive compound.
Single-frequency trolling motor installations
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic
cable ties.
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult
your boat dealer or manufacturer. Other tools are a wooden craft stick
or similar tool for stirring and applying epoxy, and a paper plate or
piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100
grit sandpaper, specially formulated epoxy adhesive available from LEI
(see ordering information on the inside back cover). A sandwich hull
also requires polyester resin.
Selecting a Transducer Location
1. The location must be in the water at all times, at all operating speeds.
2. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is not placed in a smooth flow of
14

water, interference caused by bubbles and turbulence will show on the
sonar's display in the form of random lines or dots whenever the boat is
moving.
NOTE:
Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence at high speed. These boats
typically have large outboard motors capable of propelling the boat
at speeds faster than 35 mph. Typically, a good transom location on
aluminum boats is between the ribs closest to the engine.
3. The transducer should be installed with its face pointing straight
down, if possible. For shoot-thru applications: Many popular fishing
boat hulls have a flat keel pad that offers a good mounting surface. On
vee hulls, try to place the transducer where the deadrise is 10° or less.
Deadrise less than 10°
Strakes
Pad
Vee pad hull (left); Vee hull (right). A pod style transducer is shown
here, but the principle is the same for Skimmers inside a hull.
4. If the transducer is mounted on the transom, make sure it doesn't
interfere with the trailer or hauling of the boat. Also, don't mount it
closer than approximately one foot from the engine's lower unit. This
will prevent cavitation (bubble) interference with propeller operation.
5. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps and aerators can
be displayed on the sonar's screen. Use caution when routing the trans-
ducer cable around these wires.
CAUTION: Clamp the trans-
ducer cable to transom near
the transducer. This will help
prevent the transducer from
entering the boat if it is
knocked off at high speed.

Align transducer centerline with hull bottom. A dual frequency

How low should you go?
For most situations, you should install your Skimmer transducer so
that its centerline is level with the bottom of the boat hull. This will
usually give you the best combination of smooth water flow and protec-
tion from bangs and bumps.
However, there are times when you may need to adjust the transducer
slightly higher or lower. (The slots in the mounting brackets allow you
to loosen the screws and slide the transducer up or down.) If you fre-
quently lose bottom signal lock while running at high speed, the trans-
ducer may be coming out of the water as you cross waves or wakes.
Move the transducer a little lower to help prevent this.
If you cruise or fish around lots of structure and cover, your transducer
may be frequently kicking up from object strikes. If you want, you may
move the transducer a little higher for more protection.
There are two extremes you should avoid. Never let the edge of the
mounting bracket extend below the bottom of the hull. Never let the
bottom – the face – of the transducer rise above the bottom of the hull.
Shoot-Thru-Hull vs. Transom Mounting
In a shoot-thru-hull installation, the transducer is bonded to the inside
of the hull with epoxy. The sonar "ping" signal passes through the hull
and into the water. This differs from a bolt-thru-hull installation (often
called "thru-hull"). In that case, a hole is cut in the hull and a specially
designed transducer is mounted through the hull with a threaded shaft
and nut. This puts the transducer in contact with the water.
Typically, shoot-thru-hull installations give excellent high speed opera-
tion and good to excellent depth capability. There is no possibility of
transducer damage from floating objects, as there is with a transom-
mounted transducer. A transducer mounted inside the hull can't be

knocked off when docking or loading on a trailer.
The shoot-thru-hull installation does have its drawbacks. First, some
loss of sensitivity does occur, even on the best hulls. This varies from
hull to hull, even from different installations on the same hull. This is
caused by differences in hull lay-up and construction.
Second, the transducer angle cannot be adjusted for the best fish arches
on your sonar display. (This is not an issue for flasher-style sonars.)
Lack of angle adjustment can be particularly troublesome on hulls that
sit with the bow high when at rest or at slow trolling speeds.
Third, a transducer CAN NOT shoot through wood and metal hulls.
Those hulls require either a transom mount or a thru-hull installation.
Fourth, if your Skimmer transducer has a built in temp sensor, it will
only show the temperature of the bilge, not the water surface temp.
Follow the testing procedures listed in the shoot-thru-hull installation
section of this instruction booklet to determine if you can satisfactorily
shoot through the hull.
Transom Transducer Assembly and Mounting
The best way to install these transducers is to loosely assemble all of
the parts first, place the transducer's bracket against the transom and
see if you can move the transducer so that it's parallel with the ground.
The following instructions sometimes vary depending on the mounting
bracket that came with your transducer. Single frequency Skimmers
come with a one-piece stainless steel bracket, while dual frequency
Skimmers come with a two-piece plastic mounting bracket. Use the set
of instructions that fits your model.
1. Assembling the bracket.
A. One-piece bracket: Press the two small plastic ratchets into the
sides of the metal bracket as shown in the following illustration. Notice
there are letters molded into each ratchet. Place each ratchet into the
bracket with the letter "A" aligned with the dot stamped into the metal
bracket. This position sets the transducer's coarse angle adjustment for a
14° transom. Most outboard and stern-drive transoms have a 14° angle.

B. Two-piece bracket: Locate the four plastic ratchets in the trans-
ducer's hardware package. Press two ratchets into the sides of the
plastic bracket and two on either side of the transducer as shown in
the following illustrations. Notice there are letters molded into each
ratchet.
Place the ratchets into the bracket with the letter "A" aligned with the
alignment mark molded into the bracket. Place the ratchets onto the
transducer with the letter "A" aligned with the 12 o'clock position on
the transducer stem. These positions set the transducer's coarse angle
adjustment for a 14° transom. Most outboard and stern-drive tran-
soms have a 14° angle.

2. Aligning the transducer on the transom.
A. One-piece bracket: Slide the transducer between the two ratch-
ets. Temporarily slide the bolt though the transducer assembly and
hold it against the transom. Looking at the transducer from the side,
check to see if it will adjust so that its face is parallel to the ground.
If it does, then the "A" position is correct for your hull.
If the transducer's face isn't parallel with the ground, remove the
transducer and ratchets from the bracket. Place the ratchets into the
holes in the bracket with the letter "B" aligned with the dot stamped
in the bracket.
Reassemble the transducer and bracket and place them against the
transom. Again, check to see if you can move the transducer so it's
parallel with the ground. If you can, then go to step 3A. If it doesn't,
repeat step 2A, but use a different alignment letter until you can
place the transducer on the transom correctly.

B. Two-piece bracket: Assemble the transducer and bracket as
shown in the following figure. Temporarily slide the bolt though the
transducer assembly but don't tighten the nut at this time. Hold the
assembled transducer and bracket against the transom. Looking at the
transducer from the side, check to see if it will adjust so that its face is
parallel to the ground. If it does, then the "A" positions are correct for
your hull.

If the transducer's face isn't parallel with the ground, remove and
disassemble the transducer and ratchets. Place the ratchets into the
bracket holes with the letter "B" aligned with the bracket alignment
mark. Place them on the transducer aligned with the 12 o'clock posi-
tion on the transducer stem.
Reassemble the transducer and bracket and place them against the
transom. Again, check to see if you can move the transducer so it's
parallel with the ground. If you can, then go to step 3B. If it doesn't,
repeat step 2B, but use a different alignment letter until you can
place the transducer on the transom correctly.
3. Assembling the transducer.

the ratchets, assemble the transducer as shown in the following fig-
ure. Don't tighten the lock nut at this time.

4. Drilling mounting holes.
Hold the transducer and bracket assembly against the transom. The
transducer should be roughly parallel to the ground. The trans-
ducer's centerline should be in line with the bottom of the hull. Don't
let the bracket extend below the hull!
Mark the center of each slot for the mounting screw pilot holes. You
will drill one hole in the center of each slot.
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10
screws). For the two-piece bracket, use the #20 bit (for the #12
screws).

5. Attaching transducer to transom.
A. One-piece bracket: Remove the transducer from the bracket and
re-assemble it with the cable passing through the bracket over the
bolt as shown in the following figures.
For single-frequency Skimmer, route cable over bolt and through
bracket. Side view shown (left) and seen from above (right).
Both bracket types: Attach the transducer to the transom. Slide the
transducer up or down until it's aligned properly with the bottom of
the hull as shown in the preceding and following figures. Tighten the
bracket's mounting screws, sealing them with the sealant compound.
Adjust the transducer so that it's parallel to the ground and tighten
the nut until it touches the outer washer, then add 1/4 turn. Don't
over tighten the lock nut! If you do, the transducer won't "kick-up" if
it strikes an object in the water.

6. Route the transducer cable through or over the transom to the so-
nar unit. Make sure to leave some slack in the cable at the transducer. If
possible, route the transducer cable away from other wiring on the boat.
Electrical noise from the engine's wiring, bilge pumps, VHF radio wires
and cables, and aerators can be picked up by the sonar. Use caution
when routing the transducer cable around these wires.
WARNING:
Clamp the transducer cable to the transom close to the
transducer. This can prevent the transducer from enter-
ing the boat if it is knocked off at high speed.
If you need to drill a hole in the transom to pass the connector through,
the required hole size will be 5/8".
Caution:
If you drill a hole in the transom for the cable, make sure it is lo-
cated above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline seal-
ant used for the mounting screws.
7. Make a test run to determine the results. If the bottom is lost at
high speed, or if noise appears on the display, try sliding the transducer
bracket down. This puts the transducer deeper into the water, hope-
fully below the turbulence causing the noise. Don't allow the transducer
bracket to go below the bottom of the hull!
Trolling Motor Bracket Installation
(single-frequency only)
1. Attach the optional TMB-S bracket to the transducer as shown in the
following figure, using the hardware supplied with the transducer.

sition the transducer to aim straight down when the motor is in the
water. Tighten the strap securely.

3. Route the transducer cable alongside the trolling motor shaft. Use
plastic ties (not included) to attach the transducer cable to the troll-
ing motor shaft. Make sure there is enough slack in the cable for the
motor to turn freely. Route the cable to the sonar unit and the trans-
ducer is ready for use.

Transducer Orientation and Fish Arches
If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest
in the water or at slow trolling speeds. If the arch slopes up – but not
back down – then the front of the transducer is too high and needs to be
lowered. If only the back half of the arch is printed, then the nose of the
transducer is angled too far down and needs to be raised.

NOTE:
Periodically wash the transducer's face with soap and water to re-
move any oil film. Oil and dirt on the face will reduce the sensitivity
or may even prevent operation.
Shoot-Thru-Hull Preparation
Hulls With Flotation Materials
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass lay-
ers. The sonar signal must pass through solid fiberglass. A successful
transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood or foam) between layers of fiberglass if
the material is removed from the chosen area. See the figure below.
WARNING:
Do not remove any material from your inner hull unless
you know the hull's composition. Careless grinding or
cutting on your hull can result in damage that could sink
your boat. Contact your boat dealer or manufacturer to
confirm your hull specifications.
Fill with resin

Flotation material
Inner hull
Epoxy to hull first
Outer hull
Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass,
then a core of balsa wood, finishing with an outer layer of fiberglass.
Removing the inner layer of fiberglass and the balsa wood core exposes
the outer layer of fiberglass. The transducer can then be epoxied directly
to the outer layer of fiberglass. After the epoxy cures for 24 hours, fill the
remaining space with polyester resin. When the job is finished, the hull
is watertight and structurally sound. Remember, the sonar signal must
pass through solid fiberglass. Any air bubbles in the fiberglass or the
epoxy will reduce or eliminate the sonar signals.
Testing Determines Best Location
Ideally, the shoot-thru transducer should be installed as close to the
transom as possible, close to the centerline. This will give you the best
performance during high speed maneuvers.

Shoot-thru-hull transducer locations for
high speed or trolling speed operation.
To choose the proper location for shoot-thru-hull mounting, follow these
testing procedures: (You may need a helper to complete these steps.)
1. Anchor the boat in about 30 feet of water. Add a little water to the
sump of the boat. Plug the transducer into the sonar unit, turn it on,
then hold the transducer over the side of the boat in the water. Adjust
the sensitivity and range controls until a second bottom echo is seen on
the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range
and ASP. Try a range setting that is two to three times the water
depth. The harder (more rocky) the bottom, the easier it will be to get a
second bottom signal.) Don't touch the controls once they've been set.

Second bottom
Manual range setting
Example of a second bottom signal. Unit is in 30 feet of water with
range set at 80 feet and sensitivity set at 87 percent.
2. Next, take the transducer out of the water and place it in the water
in the sump of the boat, face down. Notice how the signal strength
decreases. The second bottom signal will probably disappear and the
bottom signal intensity will likely decrease.

3. Now move the transducer around to find the best location with the
strongest possible bottom signal. If you find a spot with an acceptable
bottom signal, mark the location and move on to step 4.
If you can't get an acceptable bottom signal, try turning up the sensi-
tivity by three or five keystrokes and then move the transducer around
once more. If you find a spot that works, mark it and move on to step 4.
If you have to turn up sensitivity by more than five keystrokes to get
a good signal, the transducer should be mounted on the outside of the
hull. This is especially true if you have to turn sensitivity all the way
up to get a decent bottom signal.
4. Most people can get good results by following steps 1 through 3, so this
step is optional. If you want to make an extra effort to be absolutely sure
that your selected location will work under all conditions, make a test
run with the boat on plane and observe the bottom signal.
You'll need to figure some way to prop the transducer into position while
you make your test run. (A brick or two might be sufficient to hold it in
place.)
5. When you're satisfied with a location, mark it and proceed with the
installation.
Shoot-Thru-Hull Installation
If you are installing the transducer on a hull with floatation material
sandwiched within the hull, refer to the text "Hulls With Flotation Ma-
terials" beginning on page 24.
1. Make sure the area is clean, dry and free of oil or grease, then sand
both the inside surface of the hull and the face of the transducer with
100 grit sandpaper. The sanded hull area should be about 1-1/2 times
the diameter of the transducer. The surface of the hull must be flat
so the entire transducer face is in contact with the hull prior to
bonding. After sanding, clean the hull and transducer with rubbing
alcohol to remove any sanding debris.

WARNING:
Use only the epoxy available from LEI. It has been for-
mulated to work with these installation procedures.
Other epoxy types may be too thin or may not cure to the
right consistency for optimum transducer performance.
2. The epoxy consists of the epoxy itself and a hardener. Remove the
two compounds from the package and place them on the paper plate.
Thoroughly stir the two compounds together until the mixture has a
uniform color and consistency. Do not mix too fast or bubbles will
form in the epoxy. After mixing, you have 20 minutes to complete the
installation before the epoxy becomes unworkable.
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face
of the transducer as shown in the previous figure. Make sure there
are no air pockets in the epoxy layer! Then, apply the remaining ep-
oxy to the sanded area on the hull.
3. Press the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. Stop pressing
when you bottom out on the hull. When you're finished, the face of
the transducer should be parallel with the hull, with a minimum
amount of epoxy between the hull and transducer.
4. Apply a weight, such as a brick, to hold the transducer in place while
the epoxy cures. Be careful not to bump the transducer while the ep-
oxy is wet. Leave the weight in place for a minimum of three hours.
Allow the epoxy to cure for 24 hours before moving the boat.
5. After the epoxy has cured, route the cable to the sonar unit and it's
ready to use.

Speed/Temperature Sensors
Optional Speed Sensor Installation
All the units in this series can display speed and distance traveled, but
only the LMS-339cDF iGPS comes packed with a speed sensor. If you
want to purchase an optional additional sensor for your unit, refer to
the accessory ordering information inside the back cover of this man-
ual. The following instructions describe how to install the speed sensor.
Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit
for pilot holes, screwdriver. Required supplies for this job include: four
#8 stainless steel wood screws (3/4" long), high quality, marine grade
above- or below-waterline sealant.
First find a location on the boat's transom where the water flow is
smoothest. Don't mount the sensor behind strakes or ribs. These will
disturb the water flow to the speed sensor. Make sure the sensor will
remain in the water when the boat is on plane. Also make sure the lo-
cation doesn't interfere with the boat's trailer. Typically, the sensor is
mounted about one foot to the side of the transom's centerline.
Once you've determined the proper location for the unit, place the sen-
sor on the transom. The bottom of the bracket should be flush with the
hull's bottom. Using the sensor as a template, mark the hull for the
screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not
included). Use a high quality, marine grade above- or below-waterline
sealant to seal the screws. Make sure the sensor is flush with the bot-
tom of the hull and tighten the screws.

Speed sensor mounting configuration:
side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the tran-
som and the sensor with the sealant compound. This will help ensure a
smooth water flow.
Route the sensor's cable through or over the transom to the sonar unit.
If you need to drill a hole in the transom to pass the connector through,
the required hole size is 7/8".
CAUTION:
If you drill a hole in the transom for the cable, make sure it is lo-
cated above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline seal-
ant used for the screws.
The sensor is now ready for use. Connect the sensor to the sonar socket
on the back of your unit and connect the transducer to the speed sen-
sor's socket. If you have any questions concerning the installation of the
sensor, please contact your local boat dealer.
Power Connections
Your unit comes with a power/data cable that splits into three ends,
each with several exposed wires (shown in the following figure). The
end with 4 wires (blue, yellow, orange and shield) is a Data cable that
connects to a NMEA 0183 interface. The end with three wires (red,
black and shield) is a power cable that connects to a NMEA 2000 buss.
(For more detailed information on NMEA 2000 or LowranceNET
networks, see the NMEA 2000 Networks General Information booklet
packed with your unit.) The thicker three-wire cable (red, black and
white) is the Power Supply for your unit (and optional external speaker
connection for some units).
Depending on your configuration, you may not use all of the wires. The
following segments include instructions for installing all the unit's
wires.

Caution
All of the wires in the power/data cable have bare ends for eas-
ier installation. The bare ends on any unused wires could cause
an electrical short if left exposed. To prevent this, you should
cover the individual wire ends – either by capping them with
wire nuts or wrapping them with electrical tape. (You should cut
off the bare wire before taping off the ends.)
Powering a NMEA 2000 Buss
(NMEA 2000 Power cable)
A NMEA 2000 buss must be connected to a 12-volt DC power source to
operate. If you have a pre-existing NMEA 2000 installation, it may al-
ready be connected to another power source. If your NMEA 2000 buss is
already powered, you can ignore the NMEA 2000 Power cable. Never
attach two power sources to a single NMEA 2000 buss.
If you need to power a NMEA 2000 buss, attach the NMEA 2000 Power
cable to an accessory power switch. The cable's red wire should be at-
tached (with the provided 3-amp fuse) to the positive terminal and the
cable's black and shield wires should both be attached to the negative
terminal.
You can attach the NMEA 2000 power cable directly to the boat's bat-
tery, but you must use the fuse and install an on-off switch so
you can shut off power to the network. If a NMEA 2000 power ca-
ble is connected directly to a battery, the NMEA 2000 network will con-
tinuously draw power and drain the battery, even though the boat, your
unit and other NMEA 2000 devices are turned off.
Caution:
Never connect a NMEA 2000 power cable to an un-switched
power supply. Failure to use a power switch will allow the
NMEA 2000 network to drain the boat's battery when the system
is not in use! When you are not using the network, you should al-
ways shut the power off.

Powering the Unit
(Power Supply cable – red and black wires)
The unit works from a 12-volt battery system. For the best results, at-
tach the unit power cable directly to the battery. You can attach the
power cable to an accessory or power buss, but you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
CAUTION:
When using the unit in a saltwater environment, we strongly rec-
ommend that you shut off the power supply to the unit power cable
when the unit is not in use. When the unit is turned off but still
connected to a power supply, electrolysis can occur in the power ca-
ble plug. This may result in corrosion of the plug body along with
the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the unit
power cable to the auxiliary power switch included in most boat
designs. If that results in electrical interference, or if such a
switch is not available, we recommend connecting direct to the
battery and installing an inline switch. This will let you shut off
power to the power cable when the unit is not in use. When you
are not using the unit, you should always shut off power to the
power cable, especially when the power cable is disconnected from
the unit.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. If the cable is not long enough, splice #18 gauge wire onto it.
The power cable has two wires, red and black. Red is the positive lead,
black is negative or ground. (There is also a white wire to power an op-
tional external speaker for some units.) Make sure to attach the in-line
fuse holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.

electric power source.
WARNING:
This product must be independently fused with the en-
closed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power buss.
If a malfunction happens inside the unit, extensive dam-
age can occur if the enclosed fuse is not used. As with all
electrical devices, this unit could be damaged to a point
that it is unrepairable and could even cause harm to the
user when not properly fused.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cables! Failure to use a 3-amp fuse will void your warranty.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
GPS Internal Antenna
The unit has a built-in 12-parallel channel GPS + WAAS antenna.
NMEA 2000 Cable Connections
NMEA 2000 is a new buss network specifically designed for boats. This is
a very young industry standard and, at the time of printing, few boats
being built now have a NMEA 2000 buss installed. Over the next few
32

years, however, NMEA 2000 will become much more common. To help
you get the most out of this technology, your Lowrance unit is designed
to work with a NMEA 2000 network. You can install a network yourself
using LowranceNET components and devices.

Connecting to a NMEA 2000 Network
Your unit can be connected to a NMEA 2000 buss, receiving sensor infor-
mation from any Lowrance units attached to the buss. Contact LEI Extras
(look inside back cover for accessory ordering information) for a NMEA
2000 buss adapter cable if you would like to do this. You can connect the
unit directly to a network port. To do so, attach the adapter cable's manual
locking collar connector to the Network port on the back of the sonar unit
and attach the other end to an available port on the NMEA 2000 buss. As
soon as the unit is connected to the network, it will begin receiving
shared information. Please note the buss must be powered to operate.
(See instructions in this section on powering a NMEA 2000 buss.)
IMPORTANT NOTE:
The data from your internal GPS receiver will not be trans-
mitted across the LowranceNET NMEA 2000 network. You
must have an LGC-2000 GPS antenna module in the network
for that to happen. Installation instructions for the LGC-
2000 and other electronic probe sensors, like the EP-10 Fuel
Flow and EP-15 Fluid Level sensor are available in the
document "Instructions for Using LowranceNET NMEA
2000 Devices with LMS-334, LMS-339 and GlobalMap 3600."
If the document is missing, contact customer service or down-
load it free at www.lowrance.com.
NMEA 0183 Wiring
(Data cable)
To exchange NMEA 0183 data, this unit has one NMEA 0183 version
2.0 communication port. Com port one (Com-1) can be used to receive
NMEA 0183 format GPS data. The com port can also transmit NMEA
0183 format GPS data to another device.
The four wires for the com port are combined with the Power Supply
cable and NMEA 2000 Power cable to form the power/data cable (shown
earlier). Com-1 uses the yellow wire to transmit, the orange wire to re-
ceive and the shield wire for signal ground. Your unit does not use the
blue wire.

Mounting the Unit: Bracket or Portable
You can install the sonar unit on the top of a dash with the supplied
gimbal bracket. It can also be mounted on a portable power supply.
If you use the supplied bracket, you may be interested in the optional
R-A-M bracket mounting system. This converts the unit's gimbal
bracket to a swivel mount.
35
Download from Www.Somanuals.com. All Manuals Search And Download.
Optional R-A-M mounting system.
Bracket Installation
Mount the unit in a convenient location, provided there is clearance
behind the unit when it's tilted for the best viewing angle. This must
be a location with a clear view of the sky, so the internal GPS
antenna can lock-on to satellite signals. Make sure there is enough
room behind the unit to attach the power and transducer cables.
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin fiber-
glass panels to reinforce the panel and secure the mounting hardware.
Front
Install the gimbal bracket. Position the bracket so the arms slope to-
ward the front of your unit.

Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers prefer to mount the bracket to the side of the cable
hole. It's a matter of personal preference.

Pass the power cable's bare-wire end down though the hole from the
top. If you want, you can fill in the hole around the cables with a good
marine sealant. (Some marine dealers stock cable hole covers to conceal
the opening.) No matter what type of installation you prefer, be sure to
leave enough slack in the cables to allow tilting or swiveling the unit. If
you choose to fill in the hole, be sure to position the cables against the
rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the
rear edge of the hole. Then, slide the bracket over the hole and butt the
rear of the bracket base firmly against the cables, pinning them in
place against the side of the hole. Finally, fasten the bracket to the
dash. Attach the unit to the gimbal bracket using the supplied gimbal
knobs and washers.

Portable Installation
Like many Lowrance products, this unit is capable of portable operation
by using an optional portable power pack (PPP). The power pack and
an optional portable transducer expand the uses for your sonar unit.
The PPP makes it easy to use the unit on your boat or take it to the
dock, on an ice fishing trip or use it as a second sonar in a friend's boat.
Most LEI portable power packs can be used with eight "D" cell alkaline
batteries. Some use an optional sealed, rechargeable battery. For in-
formation on the PPP for your unit, see the accessory ordering informa-
tion inside the back cover of this manual.
"D" cell battery

MMC or SD Card Memory Card Installation
Your unit uses a MultiMedia Card to store information, such as sonar
logs, custom maps, waypoints, trails and other GPS data. The unit can
also use Secure Digital cards (SD card) to store data.
NOTE:
Throughout this manual, we will use the term MMC, but just re-
member your unit can use an MMC or SD card to store data.
Both of these solid-state flash memory devices are about the size of a
postage stamp. An SD card is slightly thicker than an MMC. As this
manual went to press, MMCs were available in storage capacities of 8
MB, 16 MB, 32 MB, 64 MB and 128 MB. SD cards were available in
capacities of 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB, 1
GB and 2 GB. Additional MMC cards are available from LEI Extras.

Basic Sonar Quick Reference
1. Mount the transducer, antenna and unit. Connect the unit to electric
power and the transducer. (If GPS operation is desired, connect GPS
antenna, too.) Make sure the MMC is in. (See complete installation de-
tails beginning on page 13.)
2. Launch your boat.
3. To turn on the unit, press and release PWR key.
4. Opening screen displays Map Page. Rotate through the four main
Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar
Page) by pressing PAGES|← → to select Page Name|EXIT. Switch
Pages to display Sonar Page.
5. If GPS data is desired, wait while unit locates satellites and calculates
current position. When the unit acquires position, a tone sounds and a posi-
tion acquired message appears.
6. With position acquired (if desired), head for your fishing grounds.
Your unit will automatically display digital depth and surface water
temperature in the top left corner of the screen.
The auto settings will track the bottom, displaying it in the lower por-
tion of the screen. The full sonar chart will scroll from right to left,
showing you what's under the boat as you cruise across the water. You
can change the display by:
Zoom in to enlarge the chart for more detail: press ZIN.
Zoom out to return to full chart mode: press ZOUT.
7. Watch the display for the appearance of fish symbols (or arches, if
Fish I.D. is turned off). When you see fish symbols or arches, you've
found fish! Stop the boat and get your lure or bait into the water at the
depth indicated on the sonar chart.
8. Gauge the fish depth by visually comparing the fish symbols or
arches with the depth scale on the right side of the screen.
9. If you are drifting at a very low speed or anchored, you are not mov-
ing fast enough for a fish to return the tell-tale fish arch signal. As you
drift over a fish, or as a fish swims through the transducer's signal
cone, the fish echo will appear as a straight line suspended between the
surface and the bottom when Fish I.D. is turned off.
10. To turn off the unit, press and hold PWR key for three seconds.

Sonar Operations
As you can see from the quick reference on the previous page, basic operation
is pretty easy, right out of the box. If you are a sonar novice, try operating the
unit with the factory defaults until you get a feel for how it's working.
As you are learning the basics, there is one setting you might want to
tinker with from time to time — Sensitivity.
Sensitivity controls the unit's ability to pick up echoes. If you want to see
more detail, try increasing the sensitivity, a little at a time. There are situa-
tions when too much clutter appears on the screen. Decreasing the sensitivity
can reduce the clutter and show the strongest fish echoes, if fish are present.
As sensitivity is adjusted, you can see the difference on the scrolling chart.

These figures show results of different sensitivity levels on the same lo-
cation. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitivity.

sitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.

You can change the sensitivity level whether you are in Auto Sensitivity
mode or Manual Sensitivity mode. The adjustment method works the
same in both modes, but it gives you slightly different results.
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually ad-
justing a car's speed with the accelerator pedal while cruise control is on.
You can tell the car to run faster, but when you let off the gas the cruise
control automatically keeps you from running slower than the minimum
speed setting. In the unit, auto mode will let you increase sensitivity to 100
percent, but the unit will limit your minimum setting. This prevents you
from turning sensitivity down too low to allow automatic bottom tracking.
When you change the setting with auto turned on, the unit will continue to
track the bottom and make minor adjustments to the sensitivity level, with
a bias toward the setting you selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have complete manual control of the
car's speed. In the unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on wa-
ter conditions, the bottom signal may completely disappear from the
screen when you reduce sensitivity to about 50 percent or less!
Try adjusting sensitivity in both auto and manual modes to see how
they work.
To adjust sensitivity:
1. Press MENU|ENT.
2. The Sensitivity Control Bar appears. Press ↑ ↓ to adjust sensitivity.
When it's set at the desired level, press EXIT.

NOTE:
If you want to change the sensitivity in Manual Mode, turn off Auto
Sensitivity. From the Sonar Page, press MENU|↓ to AUTO SENSI-
TIVITY|ENT|↑ to SENSITIVITY|ENT. Press ↓ ↑ to pick a different sensi-
tivity setting. When it's set at the desired level, press EXIT.
Important Tip:
While you are experimenting with settings, it is possible to scram-
ble them so the sonar picture disappears from your screen. If that
happens, remember it is easy to switch back to full automatic op-
eration by restoring the factory auto settings.
To Restore Factory Settings
1. Press MENU|MENU|↓ to SYSTEM SETUP|ENT|↓ to RESET OP-
TIONS|ENT.
2. A confirmation message will appear. Press ← to YES|ENT. All op-
tions are reset and the unit reverts back to the Map Page at the
4000-mile zoom. Sonar logs and saved GPS data will be unchanged.
Fish Symbols vs. Full Sonar Chart
You may have noticed in the quick reference that we used fish arches in
full sonar chart mode for our example, and not the popular Fish I.D.
fish symbol feature.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal
return when he sees it. However, locating fish by symbol only has some
limitations.
Your sonar unit's microprocessor is remarkably powerful, but it can be
fooled. Some of the echoes calculated to be fish could be tree limbs or tur-
tles! To see what's under your boat in maximum detail, we recommend
you turn off Fish I.D. and begin learning to interpret fish arches.
Fish I.D. is most handy when you're in another part of the boat or per-
forming some task that prevents you from watching the sonar screen.
Then, you can turn on Fish I.D. and the audible fish alarm. When that
lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the
sonar detail gathered by your unit. For example, in one case fisherman
in San Francisco Bay saw clouds of clutter in the water but no fish
arches. When a down rigger was pulled up, it brought up several small
jellyfish. The fisherman switched their sonar to Fish I.D., which
screened out the schools of jellyfish and clearly showed the game fish
there as fish symbols.

Section 4: Sonar Options & Features
ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit
that constantly evaluates the effects of boat speed, water conditions
and interference. This automatic feature gives you the best display pos-
sible under most conditions.
The ASP feature is an effective tool in combating noise. In sonar terms,
noise is any undesired signal. It is caused by electrical and mechanical
sources such as bilge pumps, engine ignition systems and wiring, air
bubbles passing over the face of the transducer, even vibration from the
engine. In all cases, noise can produce unwanted marks on the display.
The ASP feature has four settings — Off, Low, Medium and High. If
you have high noise levels, try using the "High" ASP setting. However,
if you are having trouble with noise, we suggest that you take steps to
find the interference source and fix it, rather than continually using the
unit with the high ASP setting.
There are times when you may want to turn the ASP feature off. This
allows you to view all incoming echoes before they are processed by the
ASP feature.

Features menu, Noise Rejection (ASP) set to low setting (right).

Alarms
This unit has three different types alarms, Sonar, GPS and NMEA
2000. There are three Sonar alarms: Fish Alarm, Zone Alarm and
Depth Alarm.
The Fish Alarm will sound when the Fish I.D. feature determines an
echo is a fish. The Zone Alarm consists of a blue bar on the side of the
screen. Any echo on the chart that appears inside this bar triggers the
alarm. The Depth Alarm has both a Shallow and a Deep setting. Only
the bottom signal will trigger this alarm. It is most useful as an anchor
watch or shallow water alert.
Depth Alarms
The depth alarms sound a tone when the bottom signal goes shallower
than the shallow alarm's setting or deeper than the deep alarm's set-
ting. For example, if you set the shallow alarm to 10 feet, the alarm will
sound a tone if the bottom signal is less than 10 feet. It will continue to
sound until the bottom goes deeper than 10 feet.
The deep alarm works just the opposite. It sounds a warning tone if the
bottom depth goes deeper than the alarm's setting. Both depth alarms
work only off the digital bottom depth signals. No other targets will trip
these alarms. These alarms can be used at the same time or individually.

Fish Alarm
Use fish alarm to receive an audible alarm when fish or other objects
are detected by the Fish I.D. feature (Fish I.D. must be turned on for
the Fish Alarm to work). A different tone sounds for each fish symbol
size shown on the display.
To turn on fish alarm:
1. Press MENU|MENU|↓ to ALARMS|ENT|↓ to SONAR ALARMS|ENT.
2. Press ↓ to FISH ALARM|ENT. Press EXIT repeatedly to get back to the
main page.
NMEA 2000 Alarm
The NMEA 2000 Alarm can monitor multiple EP-10 Fuel Flow and EP-
15 Fluid Level sensors. You can set a threshold for each alarm in its
corresponding Percent box. Thresholds give you control over when the
alarm will go off. You may want the alarm to go off when the black wa-
ter tank is filled to 75 percent of its capacity, likewise, you may want to
know when the fuel level falls below 30 percent of tank capacity.
To get to the NMEA 2000 Alarms menu, press MENU|MENU, select
ALARMS and press ENT. Choose NMEA 2000 ALARMS and press ENT.

and press ENT. Use the ↑ ↓ keys to select the first number, then press
→ to move to the next number. When the desired percentage has been
entered, press ENT.
Tip
You do not have to set both the Full and Empty alarms. Choose Full
and Empty alarms or activate them individually.
Calibrate Speed
The speed sensor can be calibrated to compensate for inaccuracies. Be-
fore you change the setting, first calculate the percentage that the
speed is off. You will enter this percentage in a moment.
For example, if you figure the sensor is reading 10 percent faster than
actual speed, you will enter – 10 in the calibration window. If the sen-
sor is reading 5 percent slower than true speed, you will enter + 5 in
the window.
A good way to gauge your speed sensor's performance is to compare its
reading with the ground speed measured by your unit's GPS functions.
When you make a run to compare GPS ground speed to speed sensor
speed, perform your test in relatively calm water free of current, if pos-
sible. (Unless, of course, you are taking the speed of current into con-
sideration when making your calculation.) After you have a correction
figure, here's how to enter it:
1. Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to CALIBRATE WATER
SPEED|ENT.
2. Enter the number you calculated earlier. Press ↑ ↓ to change the
first character (+ or –), then press → to move the cursor to the next
number and repeat until the percentage is correct, then press EXIT.
Chart Speed
The rate that echoes scroll across the screen is called the chart speed.
The default is maximum; we recommend that you leave the speed set
there for virtually all fishing conditions.
However, you might consider experimenting with chart speed when you
are stationary or drifting very slowly. You may sometimes achieve bet-
ter images as you slow down the chart speed to match how fast you are
moving across the bottom.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed around 50 percent. If you are drifting slowly, try a chart
speed around 75 percent. When you are stationary and a fish swims

through the sonar signal cone, the image appears on the screen as a
long line instead of a fish arch. Reducing the chart speed may result in
a shorter line that more closely resembles a regular fish return.

If you do experiment with chart speed, remember to reset it to maxi-
mum when you resume trolling or moving across the water at higher
speed.
1. From the Sonar Page, press MENU|↓ to CHART SPEED|ENT.
2. The Chart Speed Control Bar appears. Press ↑ ↓ to make adjust-
ments to chart speed.
3. When it's set at the desired level, press EXIT.
ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
paints a brighter color on targets that are stronger than a preset value.
This allows you to tell the difference between a hard and soft bottom.
For example, a soft, muddy or weedy bottom returns a weaker signal
which is shown with a narrow, colored line (dark blue tinged with red
or a little yellow.) Since fish are among the weakest echoes, they show
up mostly as blue arches. A hard bottom or other relatively hard target
returns a strong signal which causes a wider brightly colored line (red-
dish yellow to bright yellow.)
If you have two signals of equal size, one with red to yellow color and
the other without, then the target with brighter color (yellow) is the
stronger signal. This helps distinguish weeds from trees on the bottom,
or fish from structure. ColorLine is adjustable. Experiment with your
unit to find the ColorLine setting that's best for you.

NOTE:
The sonar's depth capability depends on the water, bottom condi-
tions, transducer installation and other factors.
Depth Range - Upper and Lower Limits
Virtually any segment of the water column can be displayed by using
the upper and lower limit feature. This lets you pick the shallow and
deep depth range limits that are shown on the screen, provided there is
at least 10 feet between the upper and lower limit you select. For ex-
ample, a range from 12 feet to 34 feet could be used.
Changing the upper and lower limits gives you far greater control over
the depth range. This feature lets you zoom in the display in almost
unlimited combinations. Nearly any segment of the water column, from
the surface to the bottom can be shown.

FasTrack
This feature automatically converts all echoes to short horizontal lines
on the display's far right side. The graph on the rest of the screen con-
tinues to operate normally. FasTrack gives you a rapid update of condi-
tions directly under the boat. This makes it useful for ice fishing or
when you are fishing at anchor. When the boat is not moving, fish sig-
nals are long, drawn out lines on a normal chart display. FasTrack con-
verts the graph to a vertical bar graph that, with practice, makes a use-
ful addition to fishing at a stationary location.

Fish I.D. (Fish Symbols & Depths)
The Fish I.D. feature identifies targets that meet certain conditions as
fish. The microcomputer analyzes all echoes and eliminates surface
clutter, thermoclines, and other signals that are undesirable. In most
instances, remaining targets are fish. The Fish I.D. feature displays
fish symbols on the screen in place of the actual fish echoes.
There are several fish symbol sizes. These are used to designate the
relative size between targets. In other words, Fish I.D. displays a small
fish symbol when it thinks a target is a small fish, a medium fish sym-
bol on a larger target and so on.
The sonar's microcomputer is sophisticated, but it can be fooled. It can't
distinguish between fish and other suspended objects such as trotlines,
turtles, submerged floats, air bubbles, etc. Individual tree limbs ex-
tending outwards from a group of limbs is the hardest object for the
Fish I.D. feature to distinguish from fish.
You may see fish symbols on the screen when actually, there are no
fish. The reverse is also true. The illustrations on the next page show
how Fish I.D. can actually miss fish that are present.

Does that mean Fish I.D. is broken? No — the feature is interpreting
sonar returns in a specific way to help take some of the work out of
reading the screen. Remember: Fish I.D. is one of the many tools we
provide so you can analyze your sonar returns for maximum fish find-
ing information. This and other features can help you successfully "see"
beneath the boat under varied water and fishing conditions. So, prac-
tice with the unit in both the Fish I.D. mode and without to become
more familiar with the feature. Fish I.D. is off by default.

Frequency (LMS-339cDF only)
The LMS-339cDF transducer can operate at both 200 kHz and 50 kHz.
The 200 kHz frequency has a 12° cone angle and the 50 kHz frequency
has a 35° cone angle.
The default frequency is 200 kHz, which is best for use in shallow water
(about 300 feet or less). This frequency is the best choice for about 80
percent of the fresh and salt water sport fishing applications. When you
get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre-
quency is the best choice.
The 200 kHz transducer will give you better detail and definition, but
less depth penetration. The 50 kHz transducer will give you greater
depth penetration, but a little less detail and less definition. (Remember,
all sonar units typically read deeper in fresh water than in salt water.)
There is a common exception to these rules of thumb. Some fishermen
on freshwater lakes (or the ocean) using downriggers like to see them
on the sonar. In many of those cases, you'll see a 50 kHz transducer
frequency in use because the wider cone angle lets them watch the bait.

Ping Speed & HyperScroll
Ping Speed controls the rate at which the transmitter and transducer
broadcast sonar sound waves — pings — into the water. The unit has a
default ping speed of 50 percent. At normal boating speeds, this auto-
matically provides enough return echoes to refresh the screen and scroll
the chart at maximum chart speed.
However, when you are running at high speeds, or just want the fastest
possible screen update, you may want to use the HyperScroll feature.
When you change the Ping Speed to any setting greater than 50 per-
cent, the unit automatically enters HyperScroll mode.
These faster ping rates allow you to maintain a high-detail picture on
the screen, and the screen refresh rate and chart scroll speed can keep
pace with the boat as it moves quickly over the bottom terrain.
74

When using HyperScroll, you may also need to manually decrease the
sensitivity for optimum performance. Depending on water depth and
other conditions, HyperScroll may cause a second bottom echo to return
to the transducer during the next ping cycle, or sounding. This can result
in a large amount of clutter appearing on the screen. If this occurs, just
decrease the sensitivity to a level that eliminates the clutter. When you
turn HyperScroll off, you can return to your original sensitivity level.

When you boost ping speed and switch into HyperScroll, the width of
the FasTrack bar graph display doubles in width at the right side of the
screen. This allows you to better see the virtually instantaneous sonar
returns, just as you would on a flasher sonar unit. For more informa-
tion on FasTrack, see its entry in this section.

Reset Water Distance
The sonar chart's Digital Data display option includes a box that shows
distance traveled, called Water Distance. This information is calculated
from an optional water speed sensor, not the GPS. The Water Distance
window can be reset to zero using the Reset Water Distance command.
Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to RESET WATER DIS-
TANCE|ENT. The menus are cleared and the water distance is reset to 0.00.
Set Keel Offset
This unit measures water depth from the face of the transducer. Since
the transducer is installed below the water surface, the distance dis-
played by the digital depth, chart depth scale, chart cursor or fish sym-
bols is not the exact water depth.
76
Download from Www.Somanuals.com. All Manuals Search And Download.
If the transducer is 1 foot below the surface, and the screen shows the
water depth as 30 feet, then the actual depth is 31 feet.
On sailboats or other large vessels with deep drafts, the distance be-
tween the transducer installation and the keel or lower engine unit can
be several feet. In those cases, an inexact depth reading could result in
grounding or striking underwater structure. The Keel Offset feature
eliminates the need for the navigator to mentally calculate how much
water is under his keel.
Keel Offset lets you calibrate the digital depth, chart depth scale, chart
cursor depth and fish symbol depth displayed on the screen. To calibrate
the depth indicators, first measure the distance from the face of the
transducer to the lowest part of the boat. In this example, we will use 3.5
feet. This will entered as a negative 3.5 feet, which makes the depth indi-
cators perform as if the transducer's lower in the water than it really is.
1. Press MENU|MENU|↓ to Sonar Setup ENT. Use ↓ to select SET KEEL
OFFSET|ENT.
2. The Keel Offset dialog box appears. Press ↓ to change the plus (+)
sign to a minus (–) sign.
3. Press → to the first number, then press ↑ to change the number to 3
4. Press → to the second number, then press ↑ to change the number to
5, then press EXIT. The depth indicators now accurately show the depth
of water beneath the keel.
NOTE:
If knowing the exact depth of water beneath the keel is less important,
you can calibrate the depth indicators so that they show the actual wa-
ter depth from surface to bottom. To do this, first measure the distance
from the face of the transducer up to the surface (the water line on the
boat). In this example, we will use 1.5 feet. This will be entered as a
positive 1.5 feet, which makes the depth indicators perform as if the
transducer's higher in the water than it really is.
1. Press MENU|MENU|↓ to Sonar Setup ENT. Use ↓ to select SET KEEL
OFFSET|ENT.
2. The Keel Offset dialog box appears with a plus (+) sign at the
front of the box.
3. Press → to the first number, then press ↑ to change the number
to 1.
4. Press → to the second number, them press ↑ to change the num-
ber to 5, then press EXIT. The depth indicators now accurately show
the water depth from surface to bottom.

Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. Sensi-
tivity can be adjusted, because water conditions vary greatly. A low
sensitivity level (from zero to 50 percent) excludes much of the bottom
information, fish signals, and other target information.
High sensitivity levels let you see this detail, but it can also clutter the
screen with many undesired signals. Typically, the best sensitivity level
shows a good solid bottom signal with Colorline and some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the sensitiv-
ity level on water depth and conditions. When the unit is in the auto-
matic mode, sensitivity is automatically adjusted to keep a solid bottom
signal displayed, plus a little more power. This gives it the capability to
show fish and other detail.
However, situations occur when it becomes necessary to increase or de-
crease the sensitivity. This typically happens when you want to see
more detail, so an increase in sensitivity is indicated. Or, wave action
and boat wakes can create enough tiny air bubbles to clutter much of
the water column. In that case, a decrease in sensitivity is indicated to
reduce some of the clutter.
The control bar used to adjust sensitivity up or down is the same
whether the unit is in the automatic or manual mode. In automatic you
can adjust sensitivity up to 100 percent but the unit will limit your
minimum setting. In auto, the unit will continue to make small ad-
justments, allowing for the setting you selected.
In manual mode, you have complete control over sensitivity, with the
ability to set it anywhere from zero to 100 percent. Once you select a
level in manual, the unit will continue to use that exact sensitivity set-
ting until you change it or revert to auto mode.
To adjust sensitivity in auto mode:
1. Press MENU|ENT.
2. The Sensitivity Control Bar appears. Press ↑ ↓ adjust sensitivity.
When it's set at the desired level, press EXIT.
Tip:
For quicker sensitivity adjustments, try leaving the Sensitivity
Control Bar on the screen as the chart scrolls. You can see the
changes on the screen as you press the up or down arrows. This is
handy when there's a lot of clutter in the water, and you are
matching the sensitivity to rapidly changing water conditions.

Section 5: Sonar Troubleshooting
If your unit is not working, or if you need technical help, please use the
following troubleshooting section before contacting the customer service
department. It may save you the trouble of returning your unit for re-
pair. For contact information, refer to the last page, just inside the back
cover of this manual.
Unit won't turn on
1. Check the power cable's connection at the unit. Also check the wiring.
2. Make sure the power cable is wired properly. The red wire connects
to the positive battery terminal, black to negative or ground.
3. Check the fuse.
4. Measure the battery voltage at the unit's power connector. It should
be at least 10 volts. If it isn't, the wiring to the unit is defective, the
battery terminals or wiring on the terminals are corroded, or the bat-
tery needs charging.
Unit freezes, locks up, or operates erratically
1. Electrical noise from the boat's motor, trolling motor, or an accessory
may be interfering with the sonar unit. Rerouting the power and trans-
ducer cables away from other electrical wiring on the boat may help.
Route the sonar unit's power cable directly to the battery instead of
through a fuse block or ignition switch
2. Inspect the transducer cable for breaks, cuts, or pinched wires.
3. Check the transducer and power connector. Make sure it's securely
plugged in to the unit.
Weak bottom echo, digital readings erratic, or no fish signals
1. Make sure the transducer is pointing straight down. Clean the face of
the transducer. Oil, dirt and fuel can cause a film to form on the trans-
ducer, reducing its effectiveness. If the transducer is mounted inside the
hull, be sure it is shooting through only one layer of fiberglass and that it
is securely bonded to the hull. When attaching a transducer to the inside
of a hull, ONLY use the epoxy available from LEI (order information is
inside the back cover). Do NOT use RTV silicone rubber adhesive or any
other type of epoxy. The LEI epoxy is specially formulated so that it will
cure properly for shoot-through applications.
2. Electrical noise from the boat's motor can interfere with the sonar.
This causes the sonar to automatically increase its discrimination or
noise rejection feature. This can cause the unit to eliminate weaker
signals such as fish or even structure from the display.

3. The water may be deeper than the sonar's ability to find the bottom.
If the sonar can't find the bottom signal while it's in the automatic
mode, the digital sonar display will flash continuously. It may change
the range to limits far greater than the water you are in. If this hap-
pens, place the unit in the manual mode, then change the range to a
realistic one, (for example, 0-100 feet) and increase the sensitivity. As
you move into shallower water, a bottom signal should appear.
4. Check the battery voltage. If the voltage drops, the unit's transmitter
power also drops, reducing its ability to find the bottom or targets.
Bottom echo disappears at high speeds or erratic digital read-
ing or weak bottom echo while boat is moving
1. The transducer may be in turbulent water. It must be mounted in a
smooth flow of water in order for the sonar to work at all boat speeds. Air
bubbles in the water disrupt the sonar signals, interfering with its ability
to find the bottom or other targets. The technical term for this is cavitation.
2. Electrical noise from the boat's motor can interfere with the sonar.
This causes the sonar to automatically increase its discrimination or
noise rejection feature. This can cause the unit to eliminate weaker
signals such as fish or even structure from the display. Try using resis-
tor spark plugs or routing the sonar unit's power and transducer cables
away from other electrical wiring on the boat.
No fish arches when the Fish I.D. feature is off
1. Make sure the transducer is pointing straight down. This is the most
common problem if a partial arch is displayed.
2. The sensitivity may not be high enough. In order for the unit to dis-
play a fish arch, it has to be able to receive the fish's echo from the time
it enters the cone until it leaves. If the sensitivity is not high enough,
the unit shows the fish only when it is in the center of the cone.
3. Use the Zoom feature. It is much easier to display fish arches when
zoomed in on a small range of water than a large one. For example, you
will have much better luck seeing fish arches with a 30 to 60 foot range
than a 0 to 60 foot range. This enlarges the targets, allowing the dis-
play to show much more detail.
4. The boat must be moving at a slow trolling speed to see fish arches.
If the boat is motionless, fish stay in the cone, showing on the screen as
straight horizontal lines.
NOISE
A major cause of sonar problems is electrical noise. This usually ap-
pears on the sonar's display as random patterns of dots or lines. In se-
vere cases, it can completely cover the screen with black dots, or cause
the unit to operate erratically, or not at all.
92

To eliminate or minimize the effects of electrical noise, first try to de-
termine the cause. With the boat at rest in the water, the first thing
you should do is turn all electrical equipment on the boat off. Make sure
the engine is also off. Turn your sonar on, then turn off Noise Reject
[also known as the ASP feature (Advanced Signal Processing)]. Sensi-
tivity should be set at 90-95 percent. There should be a steady bottom
signal on the display. Now turn on each piece of electrical equipment on
the boat and view the effect on the sonar's display. For example, turn
on the bilge pump and view the sonar display for noise. If no noise is
present, turn the pump off, then turn on the VHF radio and transmit.
Keep doing this until all electrical equipment has been turned on, their
effect on the sonar display noted, then turned off.
If you find noise interference from an electrical instrument, trolling mo-
tor, pump, or radio, try to isolate the problem. You can usually reroute
the sonar unit's power cable and transducer cable away from the wiring
that is causing the interference. VHF radio antenna cables radiate
noise when transmitting, so be sure to keep the sonar's wires away
from it. You may need to route the sonar unit's power cable directly to
the battery to isolate it from other wiring on the boat.
If no noise displays on the sonar unit from electrical equipment, then
make sure everything except the sonar unit is turned off, then start the
engine. Increase the RPM with the gearshift in neutral. If noise ap-
pears on the display, the problem could be one of three things; spark
plugs, alternator, or tachometer wiring. Try using resistor spark plugs,
alternator filters, or routing the sonar unit's power cable away from
engine wiring. Again, routing the power cable directly to the battery
helps eliminate noise problems. Make sure to use the in-line fuse sup-
plied with the unit when wiring the power cable to the battery.
When no noise appears on the sonar unit after all of the above tests,
then the noise source is probably cavitation. Many novices or persons
with limited experience make hasty sonar installations which function
perfectly in shallow water, or when the boat is at rest. In nearly all
cases, the cause of the malfunction will be the location and/or angle of
the transducer. The face of the transducer must be placed in a location
that has a smooth flow of water at all boat speeds. Read your trans-
ducer owner's manual or the Installation instructions (Sec. 2) in this
manual for the best mounting position.

Sonar Page
The Sonar Page displays the sonar chart, a view of the water column
from the surface to the bottom. The chart scrolls across the screen from
right to left, displaying signal echoes that represent fish, structure and
the bottom. The Sonar Page is discussed in detail in Sec. 3. To get to
the Sonar Page: Press the PAGES key, then use ← → to select SONAR.
Satellite Status Page
The Satellite Status Page, shown, provides detailed information on the
status of the unit's satellite lock-on and position acquisition. To get to
the Satellite Status Page: Press the PAGES key, then use ← → to select
STATUS.
No matter what Page you are on, a flashing current position indica-
tor/question mark symbol and flashing GPS data displays indicate that
satellite lock has been lost and there is no position confirmed. The Sat-
ellite Status Page shows you the quality and accuracy of the current
satellite lock-on and position calculation.
WARNING:
Do not begin navigating with this unit until the numbers
have stopped flashing!

Satellite Status Page.
This screen shows a graphical view of the satellites that are in view. Each
satellite is shown on the circular chart relative to your position. The point in
the center of the chart is directly overhead. The small inner ring represents
45° above the horizon and the large ring represents the horizon. North is at
the top of the screen. You can use this to see which satellites are obstructed
by obstacles in your immediate area if the unit is facing north.
The GPS receiver is tracking satellites that are in bold type. The re-
ceiver hasn't locked onto a satellite if the number is grayed out, there-
fore it isn't being used to solve the position.
Beneath the circular graph are the bar graphs, one for each satellite in
view. Since the unit has twelve channels, it can dedicate one channel
per visible satellite. The taller the bar on the graph, the better the unit
is receiving the signals from the satellite.
NOTE:
One of the data display options for the Satellite Status page is "Po-
sition Error" (horizontal position error), which can appear in one of
the page's data boxes. If you turn on Position Error, it will show you
the expected error from a benchmark location. In other words, if the
Position Error box shows 50 feet, then the position shown by the
unit is estimated to be within 50 feet of the actual location.
This also gives you an indicator of the fix quality the unit currently
has. The smaller the position error number, the more accurate the
position fix. If the position error flashes dashes, then the unit hasn't
locked onto the satellites, and the number shown isn't valid.
The Satellite Status Page has its own menu, which is used for setting
various options. To access the Satellite Status Page Menu, from the
Status Page, press MENU.

The Navigation with Sonar page.
When navigating to a waypoint, your ground speed, track, distance,
bearing to the waypoint and course are all displayed.
NOTE:
Remember: when Speed, Track and Position information displays
are flashing, satellite lock has not been achieved and no position fix
has been determined. A question mark will also flash on the pres-
ent position arrow in the center of the compass rose.
Speed (ground speed) is the velocity you are making over the ground. (If
you want, you can customize the Speed data box to display Closing
Speed instead. Closing Speed is also known as velocity made good. It's
the speed that you're making toward the waypoint. For instructions,
see the Customize Page Displays entry in Sec. 8.)
Track is the heading, or the current direction you are actually travel-
ing. Bearing is the direction of a line-of-sight from your present position
to the destination. No matter what direction you are steering, the
Bearing window shows the compass direction straight to the destina-
tion from your location at the moment. Distance shows how far it is to
the waypoint you're navigating toward.
The Off Course window shows the current cross track error. This shows
the distance you are off-course to the side of the desired course line. The
course line is an imaginary line drawn from your position when you
started navigating to the destination waypoint. The course line is shown on
the Navigation Page screen (and the Map Page screen) as a dotted line.

The cross track error range is shown on the compass rose as a wide,
white, corridor enclosing the course line. The outer edges of this white
corridor represent lines that show the current cross track error range.
The default for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross
track error line, then you are 0.20 miles to the right of the desired
course. You need to steer left to return to the desired course. You can
use the ZIN or ZOUT keys to change the cross track error range.
A circular symbol showing your destination (waypoint) appears on the
screen as you approach the waypoint, as shown on the screen in the
preceding figure.
Travel Time is the time that it will take to reach your destination at
your present closing speed. (You can also customize the time data box
to show Arrival Time instead. Arrival Time is the local time it will be
when you arrive at the destination, based upon your present closing
speed and track.)
In the preceding example, the driver is headed west (a 265º track) to-
ward a waypoint 265º (bearing) away. The cross track error range
(white corridor) is 0.20 miles either side of the course. The driver is
headed toward trail waypoint 4, which is 0.3 miles away. The vehicle is
right on course. Traveling at a speed of 8 mph, the driver will arrive at
the waypoint in 2 minutes, 17 seconds. The Navigation Page has its
own menu, which is used for some advanced functions and for setting

various options. (Options and setup are discussed in Sec. 8). To access
the Navigation Page Menu, from the Navigation Page, press MENU.
Map Page
The Map Page screens show your course and track from a bird's-eye
view. By default, this unit shows the map with north always at the top
of the screen. (This can be changed. See the topic Map Orientation, in
Sec. 8.) If you're navigating to a waypoint, the map also shows your
starting location, present position, course line and destination. You,
however, don't have to navigate to a waypoint to use the map.
Map Page is the default screen that appears when you turn on the unit.
To get to the Map Page from another page: Press PAGES|← → to
MAP|EXIT. When the Map Page is displayed, a screen similar to the fol-
lowing figures appears.
The arrow in the center of the screen is your present position. It points
in the direction you're traveling. The solid line extending from the back
of the arrow is your plot trail, or path you've taken.
The map zoom range is the distance across the screen. This number
shows in the lower right corner of the screen. In the first of the follow-
ing example figures, the range is 4,000 miles from the left edge of the
map to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its
coverage area and the amount of mapping detail shown. There are 39
available map zoom ranges, from 0.02 miles to 4,000 miles.

ter). At the 0.4 mile zoom, you can see an interstate highway with an
exit, major and minor streets as well as Point of Interest icons (right).
Background map vs. MapCreate map content
The background map includes: low-detail maps of the whole world (con-
taining cities, major lakes, major rivers, political boundaries); and me-
dium-detail maps of the United States.
The medium-detail U.S. maps contain: all incorporated cities; shaded
metropolitan areas; county boundaries; shaded public lands (such as
national forests and parks); some major city streets; Interstate, U.S.
and state highways; Interstate highway exits and exit services informa-
tion; large- and medium-sized lakes and streams; and more than 60,000
navigation aids and 10,000 wrecks and obstructions in U.S. coastal and
Great Lakes waters
MapCreate custom maps include massive amounts of information not
found in the background map. MapCreate maps contain the searchable
Points of Interest database, all the minor roads and streets, all the
landmark features (such as summits, schools, radio towers, etc.); more
rivers, streams, smaller lakes and ponds and their names.
What's more important is the large scale map detail that allows your
GPS unit to show a higher level of position accuracy. For example, the
background map would show you the general outline and approximate
shape of a coastline or water body, but the higher detail in MapCreate
shows the shoreline completely and accurately. Many smaller islands
would not be included in the background map, but are in MapCreate.

In the 0.2-mile zoom example (right), the cursor has selected the Cupps
Café POI, which triggers a pop-up box with the POI name. This pop-up
box works on POIs at any zoom range.
Tip:
In some urban areas, businesses are so close to one another that
their POI icons crowd each other on the screen. You can reduce
screen clutter and make streets and other map features easier to
see by turning off the display of POIs you're not watching for. (To
see how, check the text on Map Detail Category Selection, page 154.
It shows how to use the Map Categories Drawn menu to turn indi-
vidual POI displays off and on.) Even though their display is turned
off, you can still search for POIs and their icons will pop-up when
your unit finds them for you.

Find Your Current Position
Finding your current position is as simple as turning the unit on. With-
out obstruction from dense foilage, terrain or structures, the unit auto-
matically searches for satellites and calculates its position in approxi-
mately one minute or less.
If for some reason satellite acquisition takes longer, you may be inside
a structure or vehicle or in terrain that is blocking signal reception. To
correct this, be sure you are positioned so that the unit's antenna mod-
ule has as clear a view of the sky as possible, then turn the unit off and
back on again.
Moving Around the Map: Zoom & Cursor Arrow Keys
The map is presented from a bird's eye view. The current zoom range
shows in the lower left corner of the screen.
1. Press the ZIN key (zoom in) to move in closer and see greater detail in
a smaller geographic area.
2. Press the ZOUT key (zoom out) to move farther away and see less map
detail, but a larger geographic area.
When you are traveling, the map will automatically move as you move.
This keeps your current location roughly centered on the screen.
You can manually pan or scroll the map northward, southward, east-
ward or westward by using the arrow keys, which launch the cursor
crosshairs. This allows you to look at map places other than your cur-
rent position. To clear the cursor, press EXIT, which jumps the map
back to the current position or the last known position.
Tip:
Use the cursor to determine the distance from your current position
(or last known position, when working indoors) to any map object or
location. Use the arrow keys to position the cursor over the object or
place. The distance, measured in a straight line, appears in the
popup data box. Press EXIT to clear the cursor.

scroll the map to some far away location or waypoint. Press EXIT to
clear the cursor and jump back to your current position on the map.
When you want to take another peek at that distant place, just
press EXIT again. You can use this trick to toggle between your cur-
rent position and your destination without a lot of scrolling.
Searching
Now that you've seen how the unit can find where you are, let's search
for something somewhere else. Searching is one of the most powerful
features in the Lowrance GPS product line.
In this example, we'll look for the nearest fast-food restaurant. For more
information on different types of searches, refer to Sec. 9, Searching.
NOTE:
This example requires the Point of Interest (POI) database included
with a high detail MapCreate 6 custom map.

6. The unit's map appears, with the cross-hair cursor highlighting the
restaurant' s POI symbol. A pop-up data box shows the POI's name,
distance and bearing. A data box at the bottom of the screen continues
to display the location's latitude and longitude.
7. To clear the search and return to the last page displayed, press EXIT
repeatedly. Before you completely exited out of the Search menus, you
could have gone looking for another place.
NOTE:
Search works from mapping and POI data loaded in the unit. If you
do not have a high-detailed custom map (containing POI data) for
the area you are searching loaded on the MMC, you may not find
anything.
Set a Waypoint
A waypoint is an electronic address, based on the latitude and longi-
tude of a position on the earth. A waypoint represents a location or des-
tination that can be stored in memory, then be recalled later for navi-
gational use.
You can create a waypoint at the cursor position on the map or at your
current position while you are navigating. A waypoint may be created
at any location by manually entering the position's latitude and longi-
tude. You can copy waypoints from your unit to your personal computer
with MapCreate software. When you want to repeat a trip, these ar-
chived waypoints can be reloaded into your GPS unit.
To create and save a Waypoint:
These first two techniques use the Quick Save method, the fastest and
easiest way to create a waypoint.
Create Waypoint at Current Position
While you are traveling, press WPT|WPT. The waypoint is saved and
automatically given a name with a sequential number, such as "way-
point 003." The waypoint symbol and number appear on the map.

NOTE:
The Quick Save method uses a default waypoint symbol, unless you
edit an existing waypoint and change its symbol. (Edit Waypoint
Symbol is described in Sec. 7.) The unit will remember the symbol
you chose and use it the next time you save a waypoint. To revert to
the default symbol, edit a waypoint and choose the original symbol
or use the Reset Options command.
Create Waypoint on Map
1. Use the arrow keys to move the cursor to the place where you want
to make a waypoint.
2. Press WPT|WPT. The waypoint is saved and automatically given a
name with a sequential number, such as "waypoint 001." The waypoint
symbol and number appear on the map.

Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family
member fall overboard. It's particularly dangerous at night or if you're
out of sight of land.
This unit has a man overboard feature that shows navigation data to
the location where the feature was activated. To activate it, press the
ZOUT and ZIN keys at the same time. Your position at the time these
keys are pressed is used as the man overboard position.
Caution:
Saving a new "Man Overboard" waypoint will overwrite the pre-
vious "Man Overboard" waypoint.
Navigate Back to MOB Waypoint
Find your way back to the accident position with the Navigation Page
or Map Page. When MOB is activated, the Navigation Page automati-
cally shows the compass rose with its bearing arrow pointing toward
the man overboard position, and the destination name says "Going To
Man Overboard." The Map Page displays a Man Overboard waypoint,
represented by a human figure, and the steering arrow points where to
steer to reach that position.

TION|ENT|← to YES|ENT. The unit stops showing navigation information.
Navigate to Cursor Position on Map
The GO TO CURSOR command: navigates to the current cursor position on
the map. It's a quick and handy way to navigate to anything you can
see on the map display.
In this example, the cursor is centered on Oologah, Oklahoma.
1. Use the cursor with the zoom in and zoom out keys to find a location
you want to go to.
2. Center the cursor over the location to select it. See the example in
the following figure. Many map items such as waypoints, Points of In-
terest, towns, etc. can be selected, and appear highlighted with a pop-
up box.
116

Other features, such as a river or a street intersection will not appear
highlighted, but the cursor will take you to those locations just the
same.
3. Press MENU|ENT and the unit will begin navigating to the location.
The Map Page will display a dotted line from your current position to the
cursor position. The Navigation Page displays a compass rose showing
navigation information to your destination. See the following examples.
The 15-mile zoom figure clearly shows the dotted course line connect-
ing your current position to your destination (left). The 40-mile zoom
(center) shows both current position and destination on screen. The
Navigation Page (right) will also show navigation information.
To stop navigating to the cursor, use the Cancel Navigation command:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to YES|ENT.
Navigate to a Point of Interest
For POIs that are in view on the map, you can easily use the Navigate
to Cursor command above. Just use the cursor to select the POI.
The other method involves searching for POIs with the Find Waypoint
command, launched with the WPT key. (See the searching example ear-
lier in this section or turn to Sec. 9, Searching, for detailed instructions
on POI searches.)
After you have looked up an item with the Find Waypoint command
make sure the GO TO WAYPOINT command is highlighted and press ENT.
The unit shows navigation information to the item. To cancel naviga-
tion, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to YES|ENT.
Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the unit as
you travel. It's a travel history, a record of the path you have taken.
Trails are useful for repeating a journey along the same track. They are
particularly handy when you are trying to retrace your trip and go back
the way you came.
117
Download from Www.Somanuals.com. All Manuals Search And Download.
On the screen, trails are represented by a solid line extending from the
back of the current position arrow.
The unit is set at the factory to automatically create and record a trail
while the unit is turned on. The unit will continue recording the trail
until the length reaches the maximum trail point setting (default is
2,000, but the unit can record trails 9,999 points long). When the point
limit is reached, the unit begins recording the trail over itself.
By default, the trail flashes once a second, making it easier to see against
the background map. With the default auto setting, this unit creates a
trail by placing a dot (trail point) on the screen every time you change di-
rections. (The methods used for creating a trail and the trail update rate
can both be adjusted or even turned off. See Sec. 8 for Trail Options.)
To preserve a trail from point A to point B, you must "turn off" the trail
by making it inactive before heading to point C or even back to point A.
When the current trail is set inactive, the unit automatically begins
recording a new trail.
To Save a Trail

2. Press ↓ to the Active Trail Name|ENT.
3. Press ↓ → to ACTIVE|ENT. This unchecks the Active option.
4. To return to the main page display, press EXIT repeatedly. As you
leave the Edit Trail menu, you will notice that a new trail starts with a
new sequential number. In the example figure below, the new trail is
number 2, showing zero points. Note that Trail 1 is inactive, but it is
still visible on the map.
118

New trail named Trail 2 is created when Trail 1 is set to inactive. New
travel will be recorded in this trail, which is active and visible. Trails
do not have to be visible in order to be active.
You can save and recall up to 10 different plot trails, which can be cop-
ied to your MMC for archiving or for transfer to your MapCreate soft-
ware.
Tip:
Another quick way to stop recording one trail and begin a new one
is to use the New Trail command: Press MENU|MENU|↓ to MY
TRAILS|ENT|ENT.
Caution:
You also have the option of completely turning off trail record-
ing, under the trail Options command. However, if the Update
Active Trail option is turned off, it will cancel the automatic
trail creation feature.
Displaying a Saved Trail
The active trail is automatically displayed on the with the factory de-
fault settings. You can selectively turn trail display off and on for any
saved or active trail. In the Saved Trails List, visible trails will have a
check mark in front of the trail name.
To turn off trail display:
1. Press MENU|MENU|↓ to MY TRAILS|ENT.
2. Press ↓ to Saved Trail list, then use ↑ ↓ to select the desired Trail
Name|ENT.

Navigating Trails
There are three methods for following a trail: visual trailing, navigating
a trail (forward) and backtracking a trail (backward). Try each method
to see which you prefer.
Visual trailing is the simplest method. It uses only the Map Page and
requires no menu commands at all. The technique works the same if
you are running a trail forward (from start to end) or backward (from
end to start.) However, visual trailing provides no navigation informa-
tion during the trip, such as the time to your destination.
The other two methods provide a full range of navigation data and work
with both the Map Page and Navigation Page. The only difference be-
tween them is navigating a trail follows a trail forward while back-
tracking follows a trail in reverse.
When hiking at walking speed with a hand-held GPS, we often just use
visual back trailing because it is a bit better at following each little
turn on a foot path. At faster speeds, such as the highway or on the wa-
ter, the Navigate Trail and Backtrack Trail commands are useful.
Visual Trailing
1. On the Map Page, zoom (ZIN or ZOUT) so your flashing trail is visible.
2. Begin moving and watch the Map Page. Walk or steer so your cur-
rent position arrow traces along the trail.
Tip:
Generally, when using this method, the smaller the zoom range, the
more accurately you will be able to steer along the trail.
Navigate a Trail
The following figures illustrate the menu sequence for navigating a
trail.
1. Press MENU|MENU|↓ to MY TRAILS|ENT.

Routes
A route is a series of waypoints, linked together in an ordered sequence
to mark a course of travel. You can visualize a route as a string of
beads. The beads represent waypoints and the string represents the
course of travel connecting waypoint to waypoint.
The course from one waypoint to the next is a leg. Routes are composed
of one or more legs. The legs of all GPS routes are based on straight
lines between waypoints.
A route provides the automatic capability to navigate through several
waypoints without having to reprogram the unit after arriving at each
129

waypoint. Once programmed into the GPS unit, a route provides the
option of navigating forward through the route waypoints or in reverse
order (you can even begin navigating in the middle of a route!)
Create and Save a Route
You have the option of creating and editing a route in the unit, or you
can make a route on your computer with our MapCreate 6 software.
PC-created Routes
MapCreate is the easiest method for preparing a route, because your
PC's larger screen, keyboard and mouse are easier to manipulate than
the unit.
To load a MapCreate route into the unit, follow instructions in MapCre-
ate's manual for creating a route and saving it as part of a GPS Data File
(file format *.usr). Copy the GPS Data File to an MMC and insert the
MMC in the unit. (See Sec. 2 for instructions on installing MMCs. To
load the GPS Data File into the unit's memory, see the entry on Transfer
Custom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.)
Routes Created in the Unit
You can create a route by selecting existing waypoints from the way-
point list or you can set a series of route waypoints on the map with
cursor arrows and the Enter key. In this example, we'll create a route
from the map.

Section 8: System & GPS Options
Alarms
This unit has several GPS alarms. By default, all the alarms are turned
on with the exception of the anchor alarm. You can turn the alarms off
and on and change their distance settings.
You can set an arrival alarm to flash a warning message and sound a
tone when you cross a preset distance from a waypoint. For example, if
you have the arrival alarm set to .1 mile, then the alarm will flash a
message when you come within .1 mile of the recalled waypoint.
The off course alarm warns you when your track drifts too far to the
right or left of the course line to the waypoint. For example, if the
alarm is set to .1 mile, then the alarm flashes a message if you drift .1
miles to the right or left of the line to the waypoint.
The anchor alarm is triggered when you drift outside of a preset radius.
Using the .1 mile as an example, if you're anchored and the boat moves
more than .1 miles, a tone will sound and a message will appear.

IMPORTANT ALARM NOTES
Anchor Alarm - The anchor alarm may be triggered even when
you're sitting still. This can happen when using a small (less than
.05 mile) anchor alarm range.
Arrival Alarm - If you set the arrival alarm's distance to a small
number and you run a route (see the Navigate Routes segment),
this unit may not show navigation data to the next waypoint, once
you arrive at the first one. You may not be able to come close
enough to the first waypoint to trip the arrival alarm.
NMEA 2000 Alarm
The NMEA 2000 Alarm can be set to monitor multiple EP-10 Fuel Flow
and EP-15 Fluid Level sensors. You can set a threshold for each alarm
in its corresponding Percent box. Thresholds give you control over when
the alarm will go off. You may want the alarm to go off when the black
water tank is filled to 75 percent of its capacity, likewise, you may want
to know when the fuel level falls below 30 percent of tank capacity.
To get to the NMEA 2000 Alarms menu, press MENU|MENU, select

entered, press ENT.
Tip
You do not have to set both the Full and Empty alarms. Choose
both Full and Empty alarms or activate them individually.
Auto Satellite Search
To lock on to the satellites, the GPS receiver needs to know its current
position, UTC time and date. Altitude is also used in the equation, but
it's rarely required to determine a position. It needs this data so it can
calculate which satellites should be in view. It then searches for only
those satellites.
When your GPS receiver is turned on for the first time, it doesn't know
what your position or altitude is. It knows the current UTC time and date
since these were programmed into it at the factory and an internal clock
keeps the time while the unit is turned off. If the time and/or date are in-
correct, you can set them using the Set Local Time menu. The unit begins
searching for the satellites using the above data that it acquired the
last time it was turned on. This probably was at the factory. Since it's
almost certain that you're not at our factory, it's probably looking for
the wrong satellites.
If it doesn't find the satellites it's looking for after approximately one
minute, it switches to Auto Search. The receiver looks for any satellite
in the sky. Due to advanced technology, the auto search time has
shrunk significantly from the early days of GPS. Once the unit locks on
to the satellites, it should take less than a minute to find your position the
next time it's turned on, as long as you are approximately 100 miles from
the last location it was used.

British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are the national coordinate system used only in
their respective countries. In order to use these grid systems, you must
be in the respective country. This unit will pick the matching datum for
you when you select the grid. See the entry on Map Datum Selection for
more information.
The Military Grid Reference System (MGRS) uses two grid lettering
schemes, which are referred to as standard and standard + 10 MGRS
on this unit. Your position and datum in use determines which one to
use. If you use standard, and your position is off significantly, then try
the alternate.
NOTE:
When the position format is changed, it affects the way all positions
are shown on all screens. This includes waypoints.

Map Fix
Map Fix is used with charts or maps. This system asks for a reference
position in latitude/longitude, which you take from a marked location
on the map. It shows the present position as distance on the map from
that reference point.
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you
then measure up four inches and to the left a half-inch from the refer-
ence point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take
your map of the area and determine a reference latitude/longitude.
(Note: in order for this system to work, the latitude/longitude lines
must be parallel with the edge of the map. USGS maps are parallel,
others may not be. Also, this works better with smaller scale maps,
such as 1:24000.) The reference position can be anywhere on the map,
but the closer it is to your location, the smaller the numbers will be
that you'll have to deal with.
Once you have decided on a reference position, you can save it as a way-
point. See the waypoint section for information on saving a waypoint.
Save the reference position as a waypoint. Exit from the waypoint
screens.
1. Press MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to COORDINATE SYSTEM|ENT.
3. Press ↓ to SETUP MAP FIX|ENT.
The screen below appears, and MAP SCALE is highlighted. Press ENT and
enter the map's scale. This is generally at the bottom of the paper map.
It's shown as a ratio, for example 1:24000. Press EXIT and the unit re-
turns to the Configure Map Fix screen.

ring diameters are based on the current zoom range. For example: at the
100 mile zoom, the screen will show two rings with your current position
in the center. The large ring touching the left and right sides of the
screen is 100 miles in diameter (same as the zoom range). The second
smaller ring is 50 miles in diameter (always 1/2 the zoom range).
The distance from your current position to the smaller ring (the ring's
radius) is 25 miles (always 1/4 the zoom range). With the arrow keys

Maps and charts are based on a survey of an area covered by the map
or chart. These surveys are called Datums. Maps using different da-
tums will show the same latitude/longitude in different locations. The
GPS system used in this unit is the WGS-84 datum, which covers the
entire world. Other datums may also cover the entire world or just a
small portion of it. It, however, can show your position using any of 191
datums To change the datum:
1. Press MENU|MENU|↓ to GPS SETUP|ENT|↓ to DATUM SELECTION|ENT.
2. Select the desired datum and press ENT.
3. To return to the main page display, press EXIT repeatedly.
Datum options for this unit are listed in the back of this manual.

In Track Up mode, map shows "N" and arrow to indicate north.
Map orientation (left) is shown in north up and track up (right).
This is fine if you're always traveling due north. What you see to your
left corresponds to the left side of the map, to your right is shown on
the right side of the map, and so on. However, if you travel any other
direction, the map doesn't line up with your view of the world.
To correct this problem, a track-up mode rotates the map as you turn.
Thus, what you see on the left side of the screen should always be to
your left, and so on. Another option is course-up mode, which keeps the
map at the same orientation as the initial bearing to the waypoint.
When either the track-up or course-up mode is on, a "N" shows on the
map screen to help you see which direction is north.
