affects the information available as well. A single wide beam has a large area of  
coverage but poor resolution of detail. A narrow beam has excellent detail, but only a  
limited area of coverage.  
900 SERIES™ INTRODUCTION  
Your 900 Series™ Ultra Wide Screen Fishing System comes in the following  
configuration:  
• Humminbird® 947c 3D Combo: Ultra Wide Screen Fishing System with  
Chartplotter (Maps) and Dual Frequency 455 kHz and 83 kHz Transducer, GPS  
Receiver included.  
3D SONAR  
Your 900 Series™ Fishing System uses a six-element transducer  
that transmits at 455 kHz and is capable of reaching depths of  
240 ft (75 m). Each transmitted beam is 16 degrees in width and  
is symmetrical. The six beams are lined up next to each other to  
provide a total coverage of 53 degrees from side to side, and 16  
degrees from front to back. Using multiple narrow beams  
together gives you a wide area of coverage for terrain  
interpretation and fish location, without sacrificing the detail  
only a narrow beam can provide. Your 900 Series™ Fishing  
System gathers information from a continuous series of these  
returned signals. It then interprets this information to create a  
detailed 3-dimensional view of the terrain passing beneath  
your boat as you travel across the water.  
HOW THE 900 SERIES™ WORKS  
Sonar uses sound waves to determine the presence and location of underwater  
objects. The time measured between the transmission of the sound wave and the  
reception of any reflection can be used to determine distance from an object. Analysis  
of the reflected signal can also be used to determine location, size, or composition of  
underwater objects.  
Humminbird® products consist of two main components: the sonar unit and the  
transducer. The sonar unit contains the transmitter and receiver, as well as the user  
controls and LCD display. The transducer is mounted beneath the water surface and  
converts electrical energy from the transmitter into mechanical pulses or sound  
waves. The transducer also receives reflected sound waves and converts them back  
into electrical signals for display on the sonar unit.  
2D SONAR  
The transmit and receive cycle is very fast. A sound wave can travel from the surface to  
a depth of 240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that  
your boat can "outrun" this sonar signal.  
Your 900 Series™ Fishing System also has the capability of  
displaying traditional 2-dimensional sonar information from  
either a 455 kHz beam or an 83 kHz beam. The 455 kHz single  
beam has the advantage of providing increased sonar  
resolution but is limited to a depth capability of 240 ft  
(75 m). The 83 kHz single beam sonar has the advantage of  
providing sonar information to 1000 ft (330 m) but the sonar  
resolution is not as great as with the 455 kHz single beam.  
A number of variables affect the nature of information which can be derived from the  
sonar return. Sonar signals generated at a higher frequency have the advantage of  
greatly increased sonar resolution, although the distance (depth) a high-frequency  
signal can travel is relatively short. A low frequency signal can travel great distances,  
but provides poor sonar resolution. The shape of the transmitted sonar signal greatly

Your 900 Series™ uses the GPS Receiver to determine the position of the boat  
automatically, and uses the zoom level settings on a particular view to select the best  
chart to display. See Viewing Cartography for more information.  
GPS AND CARTOGRAPHY  
Your 900 Series™ uses GPS and sonar to determine your position, display it on a grid,  
and provide detailed underwater information. The Global Positioning System (GPS) is  
a satellite navigation system designed and maintained by the U.S. Department of  
Defense. GPS was originally intended for military use; however, civilians may also take  
advantage of its highly accurate position capabilities, typically within +/- 10 meters,  
depending on conditions. This means that 95% of the time, the GPS receiver will read  
a location within 10 meters of your actual position. The GPS Receiver also uses  
information from WAAS (the Wide Area Augmentation System), EGNOS (the European  
Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite  
Augmentation System) satellites if they are available in your area.  
MULTI-MEDIA CARD (MMC)  
AND SD SLOT  
Your 900 Series™ supports cartography, and has two multi-  
media card (MMC)/SD slots. Optional-purchase MMC  
and/or SD cards can contain additional detailed maps. You  
can also export navigation data from your unit onto an  
MMC/SD card (see Navigation Main Menu: Export All  
Nav Data). If you insert an MMC or SD card that contains a  
more detailed chart for a particular location, your unit will  
GPS uses a constellation of satellites that continually send radio signals to the earth.  
Your present position is determined by receiving signals from up to 12 satellites and  
measuring the distance from the satellites. The GPS Receiver, when attached to your  
900 Series™, allows you to combine easy-to-use FishingGPS™ chartplotter and  
navigation capabilities with advanced fishfinding. The following GPS functionality is  
currently supported by the 900 Series™ when it is connected to a GPS Receiver:  
retrieve that chart and display it automatically.  
Multi-Media Card (MMC)  
and SD Slot  
Use the MMC/SD cards to update the software version of  
your control head. To update the software in your control head, plug in the appropriate  
MMC/SD card that contains a software update file; the unit will recognize it, will tell  
you what software version your control head is currently running, and will ask you if  
you want to update the software in the unit to match that on the MMC/SD card. You  
can obtain software updates from the www.humminbird.com website.

Use the illustration to locate the position of the MMC and SD slot cover, remove the  
cover, and then insert an MMC and/or an SD card into one or both slots - either slot can  
accept either an MMC or an SD card. The label on both types of cards should face  
down and away from you so that you’re looking at the back of the card. Press  
down on the card until it clicks into place, then replace the slot cover and tighten the  
screw snugly - do NOT overtighten, as this will not improve water resistance, and may  
damage the cover.  
NOTE: 900 Series™ supports Navionics® Gold Charts marine cartography and Navionics®  
HotMaps™ 2004 Gold for inland fishing. The 900 Series™ does not support Navionics®  
Classic Charts.  
Your 900 Series™ also comes with a built-in World map with a more detailed map of  
North America (Domestic models) or a more detailed map of Europe and Southeast  
Asia, including Australia and New Zealand (International models).

Basic installation tasks that you must perform include:  
GIMBAL MOUNTING THE CONTROL HEAD  
If you are gimbal mounting the Humminbird® 900 Series™, you can pre-assemble the  
unit in order to plan the best mounting location.  
• Installing the control head (choosing either gimbal or in-dash mounting)  
• Installing the transducer (choosing either the transom mount, inside the hull  
mount, or trolling motor mounting method)  
• Installing the GPS Receiver  
4
• Installing the Temperature Probe Accessory  
• Testing the complete installation and locking the transducer position.  
The supplied Humminbird® transducer uses a two piece kick-up mounting bracket. In  
addition, you will need to install the included GPS antenna and the included  
Temperature Probe accessory.

Gimbal Knob  
Gimbal Bracket  
• Gimbal mounting, where you use a surface on the boat, such as the dash, to  
Expansion ports - use for future accessories  
mount the control head so that it can be tilted up or down, or  
• In-dash mounting, where you cut a hole in the dash in order to allow the control  
head to be recessed into the dash, and the control head cannot be moved after  
mounting.  
Parts and tools specific to gimbal mounting are:  
• Gimbal mounting bracket and screws  
• Gimbal mounting knobs and washers  
• Phillips head screwdriver  
• 5/16" socket wrench or flat head screw driver  
• Hand drill with various drill bits  
• Marine-grade silicone sealant.

1. Place the control head into the gimbal bracket. Make sure that the straight side  
of the gimbal arm is against the back side of the control head.  
8.5"  
5"  
3.6"  
2. Place a 1" (25 mm) diameter black washer on the gimbal knob and then thread  
the knob and washer into the housing. Tighten the gimbal knob to secure the  
900 Series™ control head to the mount. Repeat step 2 for the other side.  
You can now place the control head in various locations to decide which is best for  
mounting. Rotating the mounting bracket to the top of the control head will allow for  
overhead mounting. The chosen mounting area should allow for sufficient room so the  
control head can pivot through the full tilt range and allow for easy removal and installation.  
1.25"  
NOTE: You can drill the cable pass hole underneath the gimbal bracket, allowing you to  
thread the cables through the knock-out holes in the mount; however, if you cannot drill the  
hole directly under the mounting bracket, then you will need to drill the cable pass hole  
behind the bracket, and will need to mount the hole cover there instead.  
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use  
progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.  
Fill all holes with marine grade silicone sealant.  
1
NOTE: You must have underside access to the mounting location to pass the cables through to  
the surface. Also make sure that the mounting surface is adequately supported to protect the  
control head from excessive wave shock and vibration and provide visibility while in operation.

3. After the mounting location has been determined, loosen the gimbal knobs and  
remove the control head from the gimbal bracket.  
NOTE: Alternate hole patterns are available underneath the gimbal mounting bracket, and  
may match existing holes on the boat. If you choose to use one of these alternate hole  
patterns, simply drill it out and use it to mount the bracket instead.  
4. Place the gimbal bracket in the chosen position on the mounting surface and  
mark the four mounting screw locations using a pencil or center punch.

5. Set the gimbal bracket aside and drill the four mounting screw holes using a  
5/32" (4.0 mm) drill bit.  
Cables Routed Directly Beneath Mounting Bracket  
1
6a. If the cables must pass through a hole directly beneath the mounting bracket,  
mark and drill an additional 1" (25 mm) hole centered between the four  
mounting holes. Route the cables through the grommet, then press the grom-  
met in place around the cables and into the 1" (25 mm) hole. Pass the cables out  
of the back of the mounting bracket. Using needle-nose pliers, break out the  
tabs on the rear of the mounting base. You will need to break out the cable tabs  
for the number of cables you want to run to your control head.  
6b. If the cables cannot be routed directly beneath the mounting bracket, mark and  
drill a 1" (25 mm) hole that will allow you to run the cables close to the bracket.  
Pass the cables through the 1" (25 mm) hole, routing the cables through the  
grommet and pressing the grommet into place. Place the hole cover over the  
mounting surface hole, then use it to mark the position of the two mounting  
screws. Remove the hole cover, drill the two mounting holes using a 9/64" (3.5  
mm) bit, fill them with marine-grade silicone, then replace the hole cover and  
insert the #8 Phillips countersink wood screws. Hand-tighten only.

NOTE: Be sure that the cables pass through the slots on the hole cover or gimbal bracket  
break out tabs and there is enough cable slack to allow for the control head to pivot through  
its full tilt range. Extra cable slack will also help when connecting/disconnecting the cables.

8. Insert cable connectors into the proper recesses on the cable collector insert.  
The cable connectors are keyed to prevent reverse installation, so be careful not  
to force the connectors into the wrong slots. If you don’t have a cable for every  
hole in the insert, install the blank plugs to protect the control head from the  
weather.

CONNECTING THE CONTROL HEAD POWER CABLE TO THE BOAT  
TRANSDUCER INSTALLATION  
A 6' (2 m) long power cable is included to supply power to the control head. You may  
shorten or lengthen the cable using 18 gauge multi-stranded copper wire.  
There are three different installation methods for your transducer:  
• Transom Transducer  
CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head MUST be  
connected to a 12 VDC power supply.  
• Inside the Hull Transducer  
• Trolling Motor Transducer.  
The control head power cable can be connected to the electrical system of the boat at one  
of two places: a fuse panel usually located near the console, or directly to the battery.  
Find the section that describes the method of installation you will be using.  
NOTE: If the included transducer will not work for your application, you may exchange it,  
NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate  
for your application - often at very little or no charge, depending on the transducer. Call the  
Humminbird® Customer Resource Center (1-800-633-1468) for details and pricing, or visit  
www.humminbird.com, Product Support/Transducer Exchange for more information.  
NOTE: Due to the wide variety of hulls, only general instructions are presented in this  
installation guide. Each boat hull represents a unique set of requirements that should be  
evaluated prior to installation. In addition to the parts supplied, you will need a hand drill  
with various bits, a socket wrench (5/16"), a Phillips head screwdriver, and marine-grade  
silicone sealant.  
GROUND  
NOTE: Make sure that the power cable is disconnected from the control head at the  
beginning of this procedure.  
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use  
progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.  
Fill all holes with marine grade silicone sealant.  
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not  
included) that match the terminal on the fuse panel. Attach the black wire to  
ground (-), and the red wire to positive (+) 12 VDC power.  
WARNING: Do not touch an active transducer during operation, as this may cause physical  
discomfort and may result in personal injury in the form of tissue damage. Handle the  
transducer only when the power to the control head is off.  
1b. If you need to wire the control head directly to a battery, obtain and install an  
inline fuse holder and a 2.5 to 3 Amp fuse (not included) for the protection of the  
unit. Humminbird® is not responsible for over-voltage or over-current failures.  
NOTE: In order to minimize the potential for interference with other marine electronics, a  
separate power source (such as a second battery) may be necessary.  
You are now ready to install the transducer. Find the section that refers to your specific  
transducer installation method.

• It is very important to locate the transducer in an area which is relatively free of  
turbulent water. As a boat moves through the water, turbulence is generated by  
the weight of the boat, and the thrust of the propeller(s) - either clockwise or  
counter-clockwise. This turbulent water is normally confined to areas immediately  
aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immed-  
iate area of the propeller(s). Clockwise propellers create more turbulence on the  
port side. On outboard or inboard/outboard boats, it is best to locate the  
transducer at least 15" (380 mm) to the side of the propeller(s).  
TRANSOM TRANSDUCER INSTALLATION  
If you will be installing a transom mounted transducer, use the procedures in this  
section. There are several procedures you will have to perform in order to install a  
transom-mounted transducer. They are:  
• Determine transducer mounting location  
• Mount the bracket to the boat  
• Attach the pivot to the transducer  
• The best way to locate turbulence-free water is to view the transom while the boat  
is moving. This method is recommended if maximum high-speed operation is a  
high priority. If this is not possible, select a location on the transom where the hull  
forward of this location is smooth, flat and free of protrusions or ribs.  
• Mount the transducer pivot assembly to the bracket  
• Adjust the running position of the transducer  
• Route the transducer cable  
• Perform a final test of the transom transducer installation.  
• The hydrodynamic shape of your transducer allows it to point straight down  
without deadrise adjustment.  
Stepped Hull  
• On boats with stepped hulls, it may be possible to mount the transducer on the  
step. Do not mount the transducer on the transom behind a step to avoid popping  
the transducer out of the water at higher speeds; the transducer must remain in  
the water for the control head to maintain the sonar signal.  
3

• If the transom is behind the propeller(s), it may be impossible to find an area clear  
from turbulence, and a different mounting technique or transducer type should  
be considered (see Inside the Hull Transducer Installation).

you have a single layer fiberglass hull, In-hull installation is an option. See Inside the Hull  
Transducer Installation for more information.  
1. First, determine the best location on the transom to install the transducer.  
Consider the following to find the best location:

5. Align the metal mounting bracket with the  
mounting holes. The center slot should be above the  
two outer slots. (This bracket and all other hardware  
supplied is top quality stainless steel for maximum  
strength and corrosion protection.) Insert the three 1"  
(25 mm) flat head wood screws into the drilled holes,  
but do not completely tighten.  
To mount the transducer bracket to the boat:  
1. Remove the transducer mounting template from this manual. (See Appendix A,  
Transducer Mounting Template: SHS 7W).  
2. Hold the template on the transom of the  
boat in the location where the transducer  
will be installed. Align the template  
vertically, matching the lower edge of the  
transom with the bottom corner of the  
template. If your propeller moves

machine screws, toothed washers, and square nuts. The toothed washers must  
fit on the inside of the transducer ears, between the pivot and the ears. The  
square nuts will be prevented from rotating by the pocket in the back of the  
pivot. An Allen wrench is provided which fits all the 1/4"-20 screws, but do not

To mount the transducer pivot assembly to the bracket:  
To adjust the running position of the transducer:  
1. Slide the assembled transducer into the metal bracket from the bottom,  
aligning the large hole at the top of the bracket with the hole in the pivot.  
The transducer mounting bracket allows height and tilt adjustment, while the pivot  
bolt allows angular adjustment. These adjustments will help reduce cavitation.  
Initially, adjust the transducer as described in the following paragraphs. Further  
adjustment may be necessary to refine the installation after high-speed testing.  
2. Insert the headed pin through the pivot holes in the bracket and pivot. The  
headed pin can be inserted from either side of the bracket.  
3. Place the nylon washer over the opposite end of the headed pin. Place the  
stainless washer over the ¹⁄₄"-20 x ⁵⁄₈" screw threads, then insert into the  
opposite end of the headed pin and finger tighten only. The screw has a thread  
locking compound on the threads to prevent loosening, and should not be fully  
tightened until all adjustments are made.

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation.  
Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to  
reduce the possibility of interference. If the cable is too short, extension cables are available to  
extend the transducer cable up to a total of 50' (15 m). For assistance, contact the Customer  
Resource Center at www.humminbird.com or call 1-800-633-1468 for more information.  
NOTE: Since the transducer may need to pivot up to 90 degrees in the bracket if it strikes an object,  
make sure there is sufficient cable slack to accommodate this motion. It is best to route the cable  
to the side of the transducer so the cable will not be damaged by the rotation of the transducer.  
Tighten the Pivot Screws  
Tighten the Mounting Screws  
2. If you will be routing the cable through a hole in the transom, drill a 5/8"  
diameter (16 mm) hole above the waterline. Route the cable through this hole,  
then fill the hole with marine-grade silicone sealant and proceed to the next  
step immediately.  
5. If access to the top mounting hole is not possible due to the selected height of  
the transducer, fully tighten the two lower screws, then simply remove the  
headed pivot pin and the transducer assembly, and tighten the top screw, then  
reassemble.  
Routing the Cable  
3. Place the escutcheon plate over the cable hole and  
use it as a guide to mark the two escutcheon plate  
mounting holes. Remove the plate, drill two 9/64" (3.6  
mm) holes, then fill both holes with marine-grade  
silicone sealant. Place the escutcheon plate over the  
cable hole and attach with two #8 x 5/8" (16 mm)  
wood screws.

To route the transom transducer cable:  
The transducer cable has a low profile connector that must be routed to the point  
where the control head is mounted. There are several ways to route the transducer  
cable to the area where the control head will be installed. The most common  
procedure routes the cable through the transom into the boat.  
4. Route and secure the cable by attaching the cable  
clamp to the transom; drill one 9/64" dia. (3.5 mm) x  
5/8" deep (16 mm) hole, then fill hole with marine-  
grade silicone sealant, then attach the cable clamp  
using a #8 x 5/8" (16 mm) screw.  
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the  
transducer cable.

To perform a final test of the transom transducer installation:  
Determine the transducer mounting location:  
After transom transducer installation, please perform the final testing and then  
finalize the installation (see Test and Finish the Transducer Installation).  
Decide where to install the transducer on the inside of the hull. Consider the following  
to find the best location:  
• Observe the outside of the boat hull to find the areas that are mostly free from  
turbulent water. Avoid ribs, strakes and other protrusions, as these create  
turbulence.  
INSIDE THE HULL TRANSDUCER INSTALLATION  
If you choose to mount your transducer inside the hull of your boat, perform the  
procedures in this section. In-hull mounting generally produces good results in single  
thickness fiberglass-hulled boats. Humminbird® cannot guarantee depth performance  
when transmitting and receiving through the hull of the boat, since some signal loss  
occurs. The amount of loss depends on hull construction and thickness, as well as the  
installation position and process.  
• As a general rule, the faster the boat can travel, the further aft and closer to the  
centerline of the hull the transducer has to be located in order to remain in contact  
with the water at high speeds.  
Trial installation:  
This installation requires slow-cure two-part epoxy. Do not use silicone or any other  
soft adhesive to install the transducer, as this material reduces the sensitivity of the  
unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air  
bubbles can be purged, thus reducing signal strength.  
You will not be able to adjust the mounting after an inside the hull transducer is  
installed. It is best, therefore, to perform a trial installation first that includes running  
the boat at various speeds, in order to determine the best mounting area before  
permanently mounting the transducer.  
NOTE: In-hull mounting requires an installed and operational control head.  
1. Plug the transducer into the control head, then power up the control head.  
When the control head detects a functioning transducer, it will automatically  
enter Normal operating mode.  
Preferred Mounting Area  
2. View the sonar signal at its best by holding the transducer over the side,  
immersed in the water, so that it is pointing straight down over a known flat  
bottom. Use the display to benchmark against the sonar signal that will be  
detected once the transducer is placed in the hull.  
3. Place the transducer body face down at the identified mounting location inside  
the hull, with the end that has the mounting ears pointed towards the bow of  
the boat.

Transducer Mounted  
Inside the Hull  
4. Fill the hull with enough water to submerge the  
Permanently mount the transducer:  
transducer body. Use a sand-filled bag or other heavy  
object to hold the transducer in position. The  
transducer cannot transmit through air, and the water  
purges any air from between the transducer and the  
hull, and fills any voids in the coarse fiberglass surface.  
1. Make sure the position of the transducer is marked.  
2. Remove the water from inside the hull and thoroughly dry the mounting  
surface. If the surface is excessively rough, it may be necessary to sand the area  
to create a smooth mounting surface.  
3. Slowly and thoroughly mix an ample quantity of two-part slow cure epoxy.  
Avoid trapping air bubbles.  
5. View the sonar signal on the display and compare  
against what you observed in Step 2, making sure that  
the boat is in the same location as it was during your  
observations in Step 2. If the results are comparable,  
move on to Step 6. Otherwise, locate a new position in  
the hull and repeat Steps 3 through 5.  
6. Run the boat at various speeds and water depths while observing the screen on  
the control head. If depth performance is required, test the transducer in water  
at the desired depth. If the performance is acceptable, move on to Step 7. If the  
performance is not acceptable, repeat Steps 3 through 6.  
7. Once you have determined the best mounting location using the above steps,  
mark the position of the transducer.  
4. Coat the face of the transducer and the inside of the hull with epoxy.  
5. Press the transducer into place with a slight twisting motion to purge any  
trapped air from underneath, keeping the end of the transducer that has the  
mounting ears pointed forward, towards the bow of the boat.  
Route the cable:  
1. Once the mounting location is determined and you have marked the position of  
the transducer, route the cable from the transducer to the control head.  
NOTE: Proper operation requires the end of the transducer that has the mounting ears to  
face towards the bow of the boat.  
6. Weight the transducer so that it will not move while the epoxy is curing.  
NOTE: When the epoxy cures, no water is necessary inside the hull.  
7. If you unplugged the transducer cable at the beginning of this procedure, plug  
it back into the control head.  
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the transducer.

TROLLING MOTOR TRANSDUCER INSTALLATION  
TEST AND FINISH THE TRANSDUCER INSTALLATION  
If you want to install the transducer on a trolling motor, use this procedure. Several  
styles of the transducer are compatible with trolling motor mounting. If you have a  
trolling motor bracket, refer to the separate installation instructions that are included  
with the bracket.  
When you have installed both the control head, the transom transducer, and  
accessories and have routed all the cables, you must perform a final test before locking  
the transducer in place. Testing should be performed with the boat in the water,  
although you can initially confirm basic operation with the boat out of the water.  
NOTE: If you have installed an in-hull mount transducer, this procedure does not apply, as  
the transducer is already locked in place.  
NOTE: After trolling motor transducer installation, please perform the final testing and then  
finalize the installation (see Test and Finish the Transducer Installation).  
1. Press POWER once to turn the control head on. There will be an audible chirp  
when the button is pressed correctly. If the unit does not power-up, make sure  
that the connector holder is fully seated and that power is available.  
If you don’t have a trolling motor transducer, there are  
several options:  
• You may purchase a Trolling Motor Adapter kit that  
will allow you to mount the transducer on the trolling  
motor.  
2. If all connections are correct and power is available, the control head will enter  
Normal operation. If no transducer is detected (or one is not connected), the  
unit will go into Simulator mode and will indicate this by displaying the word  
Simulator on the control head display.  
• You may also exchange your NEW and UNASSEMBLED  
transducer (with mounting hardware included) for a  
trolling motor transducer.  
NOTE: The transducer must be submerged in water for reliable transducer detection.  
3. If the bottom is visible on-screen with a digital depth readout, the unit is  
working properly. Make sure that the boat is in water greater than 2 ft (.6 m) but  
less than the depth capability of the unit, and that the transducer is fully  
submerged, since the sonar signal cannot pass through air.  
There are also several transducer switches available that support the following  
configurations:  
• Two control heads with one transducer  
• Two transducers with one control head.  
4. If the unit is working properly, gradually increase the boat speed to test high-  
speed performance. If the unit functions well at low speeds but begins to skip  
or miss the bottom at higher speeds, the transducer requires adjustment.  
Angling the rear of the transducer downward and/or lowering the transducer  
farther into the water will help achieve depth readings at high speeds.  
NOTE: Call the Humminbird® Customer Resource Center (1-800-633-1468) for details and  
pricing, or visit www.humminbird.com for more information.

NOTE: Due to the wide variety of boat hulls, it is not always possible to obtain high speed  
depth readings.  
GPS RECEIVER INSTALLATION  
To optimize performance of the GPS receiver, mount it in an area that has full exposure  
to the sky. The effective area of reception is 10° above the horizon. Different  
circumstances determine the mounting method appropriate for your GPS receiver.  
NOTE: It is often necessary to make several incremental transducer adjustments before  
optimum high speed performance is achieved.  
Once you have reached a consistently good sonar signal at the desired speeds, you are  
ready to lock down the transducer settings.  
If you have…

1. Determine the best location to mount your GPS receiver. Preplan and test the  
cable routing to your control head before any drilling or cutting of your boat  
surfaces. If you have purchased hardware to stem mount your GPS receiver,  
follow the instructions included with that hardware to mount the stem  
(antenna pole).  
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing  
exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).  
NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your  
boat from water damage.

NO ACCESS UNDER MOUNTING LOCATION  
Follow these steps to deck mount the GPS receiver in a situation where you must route  
the cable to the side because there is no space for a cable underneath the  
mounting location.  
FINISH ROUTING THE CABLE AND CHECK  
GPS RECEIVER OPERATION  
After installing a GPS receiver, you should perform the following procedure to finish  
routing the GPS cable to the control head and to check to make sure that the control  
head is working correctly.  
1. Determine the best location, then test route the cable from the mounting  
location to the control head.  
1. Secure the cable along its path to the control head as needed with cable ties.  
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing  
exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).  
2. Plug in the GPS receiver cable into the Communications port on the control  
head. See Testing the System Installation to use the System Status start-up  
option and/or the GPS Diagnostic View to confirm a good installation.  
2. Confirm the cable length is good and route the cable from the receiver to the  
control head. If holes are required to route the cable, they must be 3/4" (19 mm)  
to allow for the cable connector. Secure the NMEA pigtail with electrical tape.

Install the temperature probe accessory:  
TEMPERATURE PROBE ACCESSORY INSTALLATION  
1. Locate an area on the transom of your boat that will be 6” to 8” or farther from  
the transducer(s). This area must also maintain contact with the water, even at  
high speeds. Do not mount the sensor directly in front of the propeller or  
outdrive, and make sure that there are no protrusions such as ribs, rows of  
rivets, or transducers directly forward of the mounting location, as these may  
affect the flow of water over the temperature probe.  
The Temperature Probe incorporates a  
temperature sensitive probe in a high-  
impact plastic housing. The module is  
intended for installation on the transom,  
and will work well on almost any boat.  
1
In addition to the parts supplied, you will  
need a hand drill with various bits,  
marine-grade silicone sealant, and a  
Phillips head screwdriver.  
2. Align the sensor in the clamp, and align it on the transom so that the lower edge  
is flush with the hull of the boat, and mark the hole location.  
3. On fiberglass hulls, it is best to start with a smaller drill bit and use progressively  
larger bits to reduce the chance of chipping or flaking the outer coating. Drill a  
1/8” (3 mm) mounting hole approximately 3/4” (19 mm) deep.  
2
4. Seal the mounting holes with marine-grade silicone sealant, and attach the  
sensor to the transom using the screw provided. Hand tighten only!  
Routing the cable to the control head:  
1. You may route the cable over the top of the transom, or drill a 5/8” (16 mm)  
diameter hole in the transom directly above the sensor and above the waterline  
to route cable through. Use the cable clamps provided to secure the cable to the  
transom of the boat. If you use a through-hole, then also use the included  
escutcheon plate to dress the hole.  
NOTE: On fiberglass hulls, it is best to start with a smaller drill bit and use progressively  
larger drill bits to reduce the chance of chipping or flaking the outer coating.  
3
2. All mounting screws not specified require a 9/64” (3.5 mm) pilot hole drilled  
approximately 5/8” (16 mm) deep. Additionally, seal any hole drilled in the  
transom of the boat with marine-grade silicone sealant (not included).

3. Route the cable to the Control Head, and insert the connector into the  
appropriate slot. Use the connector designated for accessories on the control  
head.  
2. Self Test displays results from the internal diagnostic self test, including unit  
serial number, Printed Circuit Board (PCB) serial number, software revision, total  
hours of operation and the input voltage. See System Status for more  
information about the Self Test.  
4. If the connections are correct, the Control Head will begin displaying water  
temperature information immediately (assuming that the control head is  
powered on). If the gauge fails to read properly at high speeds, adjust the height  
of the sensor on the transom.  
3. From the System Status screen, view accessory connections by pressing the  
VIEW key. See System Status for more information about the Accessory Test.  
4. From the System Status screen, see a GPS Diagnostic View by pressing the View  
key. GPS Diagnostic View shows a sky chart and numerical data from the GPS  
receiver. The sky chart shows the location of each visible GPS satellite with its  
satellite number and a signal strength bar. A dark grey bar indicates that the  
satellite is being used to determine your current position. A light gray bar  
indicates that the satellite is being monitored, but is not yet being used. See  
System Status for more information about the GPS Diagnostic View.  
TESTING THE SYSTEM INSTALLATION  
After you have completed the installation of the control head, transducer, and any  
other accessories such as the GPS receiver, and have made all the cabling connections  
required, you must test the installation before using the system. Thorough testing  
should be performed with the boat in the water; however, you can confirm basic  
operation initially with the boat out of the water as well.  
To test the installation:  
1. Press the POWER/LIGHT key on the control head once to turn on the control  
head. (There will be an audible chirp to let you know that you pressed the key,  
and the initial Title screen will appear.) If the unit does not power up, make sure  
that power is available. While the Title screen is shown on the display, press the  
MENU key to display the Start-Up Options menu. Use the UP or DOWN 4-WAY  
Cursor keys to position the cursor, then the RIGHT Cursor key to select System  
Status from the Start-Up Options menu (see the Start-Up Options Menu section  
for more information about these menu choices). The System Status Self Test  
screen will appear.  
NOTE: If you wait too long, the system will default to whichever menu mode happens to be  
highlighted, and you will have to start again.

The sonar returns from the bottom, structure and fish can be represented as either  
Structure ID® or WhiteLine®. See Sonar Menu: Bottom View for details on how to set  
the bottom view.  
REAL TIME SONAR (RTS®) WINDOW  
A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar  
View only. The RTS® Window always updates at the fastest rate possible for depth  
conditions and shows only the returns from the bottom, structure and fish that are  
within the transducer beam. The RTS® Window plots the depth and intensity of a  
sonar return. (See Sonar Menu: RTS® Window).  
The Narrow RTS® Window  
indicates the sonar intensity  
through the use of colors. Red  
indicates a strong return and  
blue indicates a weak return.  
The depth of the sonar return  
is indicated by the vertical  
placement of the return on  
the display depth scale.  
The Wide RTS® Window  
indicates the sonar intensity  
through the use of a bar  
graph. The length of the  
plotted return provides an  
indication of whether the  
return is weak or strong. The  
depth of the sonar return is  
indicated by the vertical  
placement of the return on  
the display depth scale.  
Structure ID® represents weak returns in blue and strong returns in red.  
BOTTOM PRESENTATION  
As the boat moves, the unit charts the changes in depth on the display to create a  
profile of the Bottom Contour. The type of bottom can be determined from the return  
charted on the display. A Hard Bottom such as compacted sediment or flat rock  
appears as a thinner line across the display. A Soft Bottom such as mud or sand  
appears as a thicker line across the display. Rocky Bottoms have a broken, random  
appearance.  
NOTE: A sloping bottom will be represented as a thicker line across the display. Harder  
bottoms typically will be displayed with red and softer bottoms typically will be displayed  
with blue.  
WhiteLine® highlights the strongest sonar returns in white, resulting in a distinctive  
outline. This has the benefit of clearly defining the bottom on the display.

approximately equal to the depth. Depth range is automatically selected to keep the  
bottom visible on the display. In some situations, the selected point of view may  
prevent the display of some information due to the slope of the terrain. An option is  
available to change the perspective, or viewpoint, in order to let you see information  
that would otherwise be masked by the terrain. Use the 4-WAY Cursor Control key to

2D Sonar View  
2D SONAR VIEW  
8
1
2D Sonar View is a 2-dimensional view that presents a historical log of 2D sonar  
returns. When in 2D Sonar View, your unit operates like a typical depthsounder. The  
most recent sonar returns are charted on the right side of the window; as new  
information is received, the older information is moved across the display to the left.  
There are, however, several exceptions. The 6-beam, 53 degree transducer allows you  
to search for fish with a much wider area of coverage. Only the two center beams  
provide sonar returns for the bottom contour shown on the display. The fish symbols  
shown in the 2D Sonar View are the same as those used in the 3D Sonar View, and  
provide information on the location of the fish relative to the boat (see Sonar Menu  
Tab, Fish ID+). Use the 2D Sonar View for identifying structure and bottom hardness.

NOTE: If the Depth number is flashing, it means that the unit is having trouble locating the  
bottom. This usually happens if the water is too deep, the transducer is out of the water, the  
boat is moving too fast, or for any other reason that the unit can’t accurately receive  
continuous data.

2D Zoom View increases the displayed resolution to separate sonar returns that  
are very close together, such as those caused by fish suspended close to the bottom  
or within structure. In 2D Zoom View, the display is split to show the full range view  
on the right and the zoomed view on the left. The full range view on the right also  
contains the Zoom Preview Box that shows what part of the full range view is  
shown in zoom view on the left; the Zoom Preview Box tracks the bottom in the full  
range view.

relation to the full range view. The Zoom Level, or magnification, is displayed in the  
lower left corner and can be changed to suit conditions (see 2D Sonar X-Press™ Menu:  
Zoom Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the

6-BEAM SONAR VIEW  
BIRD’S EYE VIEW  
Bird's Eye View shows a 3D perspective view of the track and the chart land contour  
from a point above and behind the boat (the eye point). As the boat turns, the eye  
point moves to follow the boat. Big Digits on this view provide digital data in a large,  
easy-to-see format.  
6-Beam Sonar View displays information from each of the six 455 kHz beams in a  
traditional 2D representation. This view displays the raw sonar returns from each  
of the beams that are used to create the 3-dimensional wire frame representation  
of the bottom in the 3D Sonar View. The 6-Beam Sonar View can be used for  
identifying structure on the bottom and sonar returns in the water column. The  
6-Beam Sonar View also provides information on sonar targets relative to the boat.  
The far right window displays sonar targets which are to the far right of the boat  
and the far left window displays sonar targets which are to the far left of the boat.  
The remaining windows display sonar targets which are successively closer to the  
boat. The width of coverage is approximately equal to the current depth.  
When you press the 4-WAY Cursor key in the Bird’s Eye View, the position of the eye point  
will shift. This allows you to move and turn the eye point so that you can look off to the  
sides, or even behind the boat. Pressing the RIGHT or LEFT arrow keys on the 4-WAY  
Cursor key turns the eye point right or left, while pressing the UP arrow key moves the  
eye point forward, and pressing the DOWN arrow key moves the eye point backward.  
Pressing the EXIT key moves the eye point back to its original position behind and  
above the boat.

CHART/BIRD’S EYE COMBO VIEW  
CHART VIEW  
Chart/Bird’s Eye Combo View shows both the Chart and Bird’s Eye views in a  
combination split screen. You can perform any of the functions for either of these  
views, but only when the view you want to control is selected as the active side  
(see Sonar X-Press™ Menu: Active Side or Navigation X-Press™ Menu: Active Side for  
more information). A green arrow points to the side that is active. You can also  
adjust the size of the left side of a split screen (see Sonar X-Press™ Menu: Split  
Position or Navigation X-Press™ Menu: Split Position for more information).  
Chart View shows cartography from the built-in UniMap™ or an optional MMC map  
for the area surrounding your current position. The current track (also known as the  
position history or breadcrumb trail) showing where the boat has been, along with  
saved tracks, waypoints, and the current route (when navigating), are overlaid on the  
chart. You can use the 4-WAY Cursor Control key to shift/pan the chart to another area.  
You can use the ZOOM (+/-) keys to zoom in and out. You can use the INFO key to get  
information on the chart objects near the cursor.

Chart View with Cursor Present  
CHART ORIENTATION  
All the chart views allow you to choose the orientation of the chart. When North-Up  
orientation is selected, True North is shown at the top of the display. In other words,  
objects located to the north of the boat are drawn above the boat. When Course-Up  
orientation is selected, the direction of motion of the boat is shown at the top of the  
display. In other words, objects ahead of the boat are drawn above the boat. In both  
orientations, the view pans automatically, so that the boat is always centered on the  
display. When the boat is stationary, it is drawn as a circle. When the boat is in motion,  
it takes on a boat shape, pointed in the direction of motion (always Up in the Course-  
Up orientation). See Navigation Menu Tab: Chart Orientation for more information.  
VIEWING CARTOGRAPHY  
In the Chart or Combo Views, there are several cartography-related functions that you  
can access using various keys.  
Zooming: Use the Plus (+) key to Zoom In and the Minus (-) key to Zoom Out showing  
the cartography at different scales. The scale is indicated on the left side of the display.  
If you zoom in beyond the available chart data, the display will go into Overzoom mode  
whereby the last available chart data is amplified to reflect the scale selected. If you  
zoom in so far that no cartography is available, a lat/lon grid will be drawn instead.  
Panning: Use the 4-WAY Cursor keys to move the chart around on the display in the  
direction of the key being pressed. When you do this, a Bullseye Cursor is drawn at the  
top of the screen and is linked to the boat by a yellow line, even if the boat is off the  
screen. At the same time, a cursor dialog box is displayed at the top of the screen with  
the distance and bearing from the boat to the cursor position and the  
latitude/longitude coordinates of the cursor. When the cursor is active on the display,  
you can also use the 4-WAY Cursor Control key to move the cursor diagonally.  
Chart Info: Use the INFO key to get detailed information about the chart. If the cursor  
is active, you will see information about the chart objects located near the cursor. If the  
cursor is not active, the Chart Info menu will appear. You can select the nearest port,  
the nearest tide station, or the nearest current station to see information about any of  
these objects.  
NOTE: The built-in UniMap™ does not contain any Port, Tide or Current information. This  
information is only available from optional-purchase MMC/SD cards.

Waypoints are stored positions that allow you to mark areas of interest or navigation  
points. Your 900 Series™ can store up to 3000 waypoints.  
Waypoints, Routes and Tracks  
Nearest Tide Station: Tide information for the nearest tide station to your present  
position will be displayed. This includes the position of the station and the times of the  
high and low tides for today’s date. A tide graph is also displayed showing the rise and  
fall of the tides for the 24 hour time period encompassing the date. You can change the  
date to look at tide information before or after the date displayed by pressing the LEFT  
or RIGHT Cursor key respectively. Press the EXIT key to remove the information box and  
the Bullseye Cursor will be centered over the tide station position. The cursor  
information boxes will indicate the distance and bearing to the tide station from your

Routes link two or more waypoints together to create a path for navigation, and are  
used in trip planning. You can link individual waypoints together by using the GOTO  
key. A route represents your intended navigation and shows the shortest path from  
each waypoint to the next. As you travel a route, staying on the route line is the most  
efficient way to get to your destination, although you should always look out for  
obstacles not shown on the chart. Your 900 Series™ can store up to 50 routes that can  
each contain up to 50 waypoints.  
Display the Waypoints Submenu: From any view, press the MENU key twice to display  
the Main Menu System, then use the RIGHT Cursor key to select the Navigation tab.

longitude, and icon before selecting Save.  
Tracks consist of detailed position history, and are displayed as a breadcrumb trail of  
trackpoints. The Current Track shows the position history since the unit was powered  
up (maximum of 20,000 trackpoints displayed). You can clear the Current Track or save  
it at any time. Your 900 Series™ can store up to 50 saved tracks, each containing  
20,000 trackpoints. The current track represents your actual path so far.  
Edit a waypoint: From the Waypoints submenu, select Edit and press the RIGHT Cursor  
key to display a list of saved waypoints. Select the waypoint you want to edit and press  
the RIGHT Cursor key. Use the 4-WAY Cursor Control key to move from field to field, and

SIMULATOR  
SYSTEM STATUS  
Use the Simulator to learn how to use your 900 Series™ before taking your boat on the  
water. The Simulator is a very powerful tool that simulates on-the-water operation,  
providing a randomly-updated display. We recommend going through this manual  
while using the Simulator, since all of the menus function and affect the display the  
way they actually do when in Normal operation.  
Use System Status to view system connections and to conduct a unit self-test. Exit  
System Status by powering your 900 Series™ off.  
The following screens are displayed in turn when you press the VIEW button when  
using System Status:  
• Self Test  
• Accessory Test  
• GPS Diagnostic View.  
SELF TEST  
Self Test displays results from the internal diagnostic self test, including unit serial  
number, Printed Circuit Board (PCB) serial number, software revision, total hours of  
operation and the input voltage.  
Simulator  
NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually  
from the Start-Up Options menu as opposed to letting the 900 Series™ enter Simulator  
automatically (as it will if a transducer is not connected and you do nothing during power  
up). Manually selecting Simulator from the Start-Up Options menu allows you to pre-  
configure your 900 Series™ for on-the-water operation. Any menu changes you make will be  
saved for later use.  
A Simulation message will appear on the display periodically to remind you that you  
are using the Simulator.

2D SONAR X-PRESS™ MENU  
ACTIVE SIDE  
(2D Sonar Views only)  
Active Side allows you to select which side of a  
Combo View will be active; key presses will only affect the active side of the screen.  
When a menu is displayed, the non-active side of the screen will be grayed out; at any  
other time, a green arrow will point to the active side. Combo Views usually display  
sonar on the left, with Chart or Bird’s Eye usually on the right. The Active Side menu  
choice is only available when a Combo View is active.  
The 2D Sonar X-Press™ Menu provides access to  
the settings most frequently used. Press the  
MENU key once while in any of the 2D Sonar  
Views to access the 2D Sonar X-Press™ Menu.  
NOTE: Menu choices will vary depending on system

SENSITIVITY  
Sensitivity controls how much detail is shown on  
UPPER RANGE  
(Advanced)  
the display. Increasing the sensitivity shows more sonar returns from small baitfish and  
suspended debris in the water; however, the display may become too cluttered. When  
operating in very clear water or greater depths, increased sensitivity shows weaker  
returns that may be of interest. Decreasing the sensitivity eliminates the clutter from  
the display that is sometimes present in murky or muddy water. If Sensitivity is  
adjusted too low, the display may not show many sonar returns that could be fish.  
Upper Range sets the shallowest depth range that will be displayed on the 2D Sonar  
View, or 3D/2D Combo View when the 2D Sonar side is active. The Upper Range menu  
choice is available when User Mode is set to Advanced (see Setup Menu Tab: User  
Mode) and can only be accessed from the 2D Sonar View, or 3D/2D Combo View when  
the 2D Sonar side is active. Upper Range is often used with Lower Range.  
For example, if you are only interested in the area between 20 and 50 feet deep, you should  
set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will  
then show the 30 foot area between 20 and 50, and will not show the surface or the bottom  
(assuming the bottom is deeper than 50 feet), and will show greater detail for that area  
between 20 and 50 feet.  
To adjust the Sensitivity:  
1. Highlight Sensitivity on the 2D Sonar  
X-Press™ menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control  
keys to increase or decrease the Sensitivity  
setting. (Low = 1, High = 20, Default = 10)  
NOTE: A minimum distance of 10 feet will be maintained between the Upper and  
Lower Range regardless of the manual settings entered.  
Sensitivity at Low  
To adjust the Upper Range:  
1. Make sure you are in Advanced Mode, then highlight Upper Range on the 2D  
Sonar X-Press™ Menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the  
Upper Range setting. (0 to 990 feet or 0 to 301 meters [International Models  
Only], Default = 0)

LOWER RANGE  
CHART SPEED  
Lower Range sets the deepest depth range that  
Chart Speed determines the speed at which the  
sonar information moves across the display, and consequently the amount of detail  
shown. A faster speed shows more information in the Sonar Views and is preferred by  
most anglers; however, the sonar information moves across the display quickly. A  
slower speed keeps the information on the display longer, but the bottom and fish  
details become compressed and may be difficult to interpret. Regardless of the Chart  
Speed setting, the RTS® Window will update at the maximum rate possible for the  
depth conditions. Adjust Chart Speed to your personal preference.  
will be displayed. Automatic is the default setting. When in automatic mode, the lower  
range will be adjusted by the unit to follow the bottom. Selecting a specific setting  
locks the depth range into Manual mode. Use both Upper and Lower Range together  
to view a specific depth range manually when looking for fish or bottom structure.  
will be displayed in the lower right corner of the screen when you start manually  
adjusting the Lower Range to indicate that you are in Manual mode.  
M
For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet  
(surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display  
will show the 0 to 30 foot range, allowing you to see a more detailed view than you would  
see if the display went all the way to the bottom.  
To adjust the Chart Speed:  
1. Highlight Chart Speed on the 2D Sonar X-Press™ Menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart  
Speed setting. (1-10, where 1 = Slow, 10 = Fastest, Default = 5)  
NOTE: A minimum distance of 10 feet will be maintained between the Upper and  
Lower Range regardless of the settings entered manually.  
BOTTOM LOCK  
To adjust the Lower Range:  
(2D Zoom View only)  
1. Highlight Lower Range on the 2D Sonar X-Press™ Menu.  
Bottom Lock changes the mode of the Zoomed view in the 2D View.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the  
Lower Range setting. (AUTO, 10 to 1000 feet, 3 to 330 meters [International

2D BEAM SELECT  
FISH ID+™  
2D Beam Select sets which sonar returns  
from the transducer will be displayed on the screen.  
Fish ID+™ uses advanced signal processing  
to interpret sonar returns, and will display a Fish Symbol when very selective  
requirements are met. When a fish is detected, a fish icon and its depth are displayed  
above the return that has been classified as being a fish. Fish symbols come in three  
different sizes to indicate the intensity of the return; in addition, there is a unique  
symbol set associated with each of the six beams, for a total of 18 possible fish symbols  
which can be displayed. The following graphic illustrates the different Fish ID+™  
symbols and shows the beams with which they are associated. For instance, a hollow  
fish facing left indicates it was detected in the far left beam and a hollow fish facing  
right indicates it was detected in the far right beam.  
When Beam Select is set to 455 kHz, the returns from the 455 kHz narrow beams will  
be displayed in all views, and the maximum depth capability of your unit will be 240  
ft (75 m).  
When set to 83 kHz, the returns from the 83 kHz wide beam will be displayed in all  
views, except for the 3D/2D Combo View, which will continue to display returns from  
both beams in their respective windows. The RTS® Window will display the returns  
from the 83 kHz wide beam.  
When Fish ID+™ is turned off, and 83 kHz returns are displayed, the 900 series™ shows  
only the raw sonar returns on the display.  
NOTE: It is important to re-set 2D Beam Select to 455 kHz when returning to water  
shallower than 240 ft (75 m) for maximum performance in the 3D views.  
To change Beam Select:  
1. Highlight Beam Select on the Sonar main menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 455 kHz  
beam or the 83kHz beam. (455 kHz, 83 kHz, Default = 455 kHz)

FISH ID SENSITIVITY  
REAL TIME SONAR  
(RTS®) WINDOW  
RTS® Window sets the RTS® Window to either Wide or Narrow, or turns it off in the  
Sonar View. The RTS® Window always updates at the fastest rate possible and only  
displays returns that are within the transducer beam. (See Getting Started - Using Your  
900 Series™: Real Time Sonar [RTS®] Window for more information.)  
Fish ID Sensitivity adjusts the threshold of  
the Fish ID+™ detection algorithms. Selecting a higher setting allows weaker returns  
to be displayed as fish. This is useful for identifying smaller fish species or baitfish.  
Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful  
when seeking larger species of fish. Fish Sensitivity is used in conjunction with Fish  
ID+™. Fish ID+™ must be On for Fish Sensitivity to affect the ability of the 900 Series™  
to identify sonar returns as fish.  
To change the RTS® Window setting:  
1. Highlight RTS® Window on the Sonar main  
menu.

900 Series™ Defaults to Simulator with a Transducer Attached  
A connected and functioning transducer will cause the newly-started 900 Series™ to  
go into Normal operating mode automatically. If, when you power up the 900 Series™,  
it goes into Simulator mode automatically, even though a transducer is already  
connected, this means that the control head is not detecting the transducer. Perform  
the following troubleshooting tasks:  
• Using the Installation Guide that also comes with your 900 Series™, check to make  
sure that the transducer cable is securely connected to the 900 Series. Reconnect  
if necessary, and power up the 900 Series™ again to see if this fixes the problem.  
• Replace the non-functioning transducer with a known good transducer if available  
and power up the control head again.  
• Check the transducer cable. Replace the transducer if the cable is damaged or  
corroded.

DISPLAY PROBLEMS  
There are several main conditions or sources of possible interference that may cause problems with the quality of the information displayed on the control head. Look in the  
following table for some symptoms of display problems and possible solutions:  
Problem  
Possible Cause  
The control head loses power at high  
speeds.  
If the power output of your boat’s engine is unregulated, the control head may be protecting itself using its over-voltage  
protection feature. Make sure the input voltage does not exceed 20 Volts.  
When the boat moves at higher speeds, the  
bottom disappears or suddenly weakens, or  
the display contains gaps.  
The transducer position may need to be adjusted. A mix of air and water flowing around the transducer (cavitation) may  
be interfering with the interpretation of sonar data. See your Installation Guide for suggestions on adjusting the  
transducer position.  
Electrical noise from the boat’s engine may be interfering with sonar reception. See Finding the Cause of Noise for more  
information.  
There are no fish detected, even when you  
know they are in the water under the boat,  
or sonar readings seem weak or faulty.  
Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down),  
or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper  
sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty.  
Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean.  
Low battery voltage may be affecting the power of signal transmission.  
Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more  
information.

531374-1_A - 947 Man.qxd 2/15/2005 7:54 PM Page 86  
FINDING THE CAUSE OF NOISE  
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference:  
Possible Source of Noise  
Isolation  
Other electronic devices  
Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the  
noise re-appears.  
The boat’s engine  
To determine whether the boat’s engine is the source of the noise, increase the RPMs while the boat is in neutral and  
stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could  
be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator  
filter, or route the control head power and transducer cables away from the engine wiring.  
Cavitation from the boat’s propeller  
Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15” (38 cm) from the  
propeller, and that the water flows smoothly over the face of the transducer at all times.
