TRANSDUCER MOUNTING PROCEDURE  
Humminbird’s high-speed transducer is supplied with your LCR. This transducer has  
been designed to give good high speed readings on most all boat designs, including  
aluminum.  
Please carefully consider the following before installing your transducer.  
TRANSDUCER MOUNTING OPTIONS  
A. Transom Mount- The Humminbird high speed transducer allows the transducer  
element to be mounted below the bottom of the boat hull keeping the transducer out  
of turbulent water and insuring good high speed operation. The transducer will

absorb the blow of any obstruction by rotating up out of the metal spring bracket  
without harming the transducer, or your boat. The transducer can be re-engaged by  
simply rotating the transducer down and snapping it back in place. (See Figure A)  
B. Inside Hull Mount- The high speed transducer can be mounted inside the hull  
(without pivot assembly) using the proper two-part epoxy, such as Humminbird’s  
epoxy kit. Even though there is some loss of signal in shooting through the hull, your  
LCR will perform well with this type of installation. You cannot shoot through the hull  
of an aluminum boat.  
C. Trolling motor Mount- This type of transducer is not supplied with your LCR. It is  
designed to mount on the foot of a trolling motor. You may exchange your un-used  
high speed transducer for a trolling motor transducer. Call the Humminbird  
Customer Service Department.  
D. Bronz Thru-Hull Mount- This transducer is not supplied with your LCR but for an  
additional cost you may exchange your un-used high speed transducer for a bronz  
thru-hull. The bronz thru-hull transducer has a threaded stem which installs through  
a hole drilled in the boat hull, leaving the housing exposed under the boat. This type  
of installation must be used for many boats with in-board engines, because there is  
no suitable location on the transom away from the noise and turbulence created by  
the prop. A bronz thru-hull transducer should be installed by qualified personnel  
only.  
The LCR will operate well at high speeds with a properly mounted transducer.  
Remember, a transducer will not work transmitting through air or through air  
bubbles.  
1. TRANSOM MOUNTING PROCEDURE  
Step 1.  
MOUNTING LOCATION- It is important that the transducer be mounted on the transom  
where water flow is in constant contact with the transducer. You may wish to observe  
the rear of the boat while it is moving through the water to determine the best mounting  
location.  
Step 2.  
BRACKET INSTALLATION (Aluminum Boats)- To install the metal bracket on an  
Download from Www.Somanuals.com. All Manuals Search And Download.  
aluminum boat locate the template on the transom between rows of rivets, or ribs that  
are on the bottom of the boat. Align the template so that the bottom corner of the  
template nearest the center of the transom is on the bottom edge of the transom.  
Once the location is determined mark and drill three 7/64” dia.. holes noted on the  
template. Attach the metal bracket using three #10 self threading screws supplied. Be  
sure to align holes in the center of the  
Bracket slots. On some aluminum boats it may be necessary to use a wood back-up  
plate. It is important to use a silicone sealant between the screwhead and bracket in  
order to prevent leaking. (See Figure C)  
Step 2.  
BRACKET INSTALLATION (Fiberglass Boats)- If your boat has a stepped transom  
located below and under the main transom, the compact transducer design allows  
mounting in this area. This mounting location is recommended for good reading at very  
high speeds. (See Figure D)  
To install the metal bracket on a fiberglass boat, locate the template on the transom in  
the same manner as for an aluminum boat. (See Figure C)  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NOTE: On boats with more than 15 degree deadrise angle it may be necessary to  
mount the transducer slightly off parallel with the water level. (See Figure E)  
Mark and drill the three 9/64” dia. holes as shown on the template. Attach the metal  
bracket using the three #10 self threading screws supplied. Be sure to align the holes so  
that they are centered vertically in the three slots found in the bracket. It is important to  
use a silicone sealant between the screwhead and bracket in order to prevent leaking.  
Step 3.  
TRANSDUCER PIVOT ASSEMBLY- Assemble the pivot to the transducer main body  
using the two ¼”x5/8” allen head screws, two 3/8” tooth washers and two, ¼” square  
nuts. Make sure the tooth washers are sandwiched between the transducer main body  
and the pivot. The square nuts are trapped inside the pivot and will not rotate as the  
allen head screws are tightened. HOWEVER, DO NOT TIGHTEN AT THIS POINT.  
(See Figure F)  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Step 4  
TRANSDUCER ASSEMBLY- Insert the transducer assembly into the metal bracket  
from the bottom. Push up until the holes in the plastic pivot align with the uppermost  
holes in the bracket. Slide the O-ring on to the headed pin and insert it through the two  
parts. Assemble by screwing the ¼”x3/8” allen head screw into the end of the pin and  
tighten. (See Figure G)  
Step 5  
ANGLE ALLIGHMENT- Set the transducer angle so that it is parallel with the bottom of  
the boat hull. Once proper alignment is achieved, tighten the two allen head screws  
Download from Www.Somanuals.com. All Manuals Search And Download.  
using the 5/32” allen wrench provided. The screws are visible through the access holes  
on each side of the metal bracket. Check to make sure the transducer main body is  
rigidly fastened to the pivot. (See Figure H)  
Step 6  
CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of  
the transducer is a minimum of ¼” below the bottom of the transom. (However, as noted  
in STEP 2, the top of the transducer cannot fall below the bottom of the transom). If it is  
not, remove the transducer assembly from the metal bracket by removing the pin  
installed during STEP 3. Loosen the metal bracket mounting screws, re-position the  
bracket utilizing it’s slotted holes, tighten and re-assemble. It may be necessary to  
replace the silicone sealant after this adjustment is made.  
NOTE: It may be necessary to make several high speed runs to adjust transducer  
either UP/DOWN or to re-adjust the angle to achieve optimum results.  
Step 7  
CABLE CLAMPS- Install cable clamps as necessary by drilling a 1/8” dia. hole for the #  
8 screw supplied.  
2. INSIDE HULL MOUNTING PROCEDURE  
Warning: In order to achieve proper results with this type installation, it is important that  
the transducer be mounted by someone familiar with the use of two part epoxy  
adhesives. For this reason, Techsonic Industries, Inc. will not be responsible for any  
damage due to the mounting of your transducer in this manner.  
NOTE: An Epoxy Kit (Part N. EPK) is available from Humminbird. This Epoxy Kit has  
been formulated for Inside Hull Transducer Installation.  
1. Select as flat an area as possible near the aft end and center of boat where the hull  
is thin and not double. If the bottom has a runner down the center of boat, select an  
area to one side of the runner, but as close to the runner as possible.  
2. Clean the inside of the boat with lacquer thinner in the area transducer is to be  
mounted. Outside of boat in this area should also be cleaned. (Not with lacquer  
thinner).  
3. Put approximately one inch of water in the bottom of the boat.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
4. Put transducer in the water. The bottom of the transducer should be in a flat area  
and should be in good contact with the bottom of the boat.  
5. Operate the LCR with the boat operating at high speed. The transducer may have to  
be moved in order to find an area where satisfactory operation is observed.  
6. When an area is found that produces satisfactory operation, mark the location of the  
transducer.  
7. Remove the water and transducer and clean the marked area and the bottom of the  
transducer thoroughly.  
8. Using the Humminbird Epoxy Kit or equivalent, mix an ample amount of epoxy  
without causing it to bubble and pour it in the area the transducer is to be mounted.  
The puddle should be larger than the bottom of the transducer.  
9. Coat the bottom of the transducer with epoxy, then put it in the center of the puddle  
and push down on the transducer while moving it around in a circular motion. This  
forces out any air bubbles that may be trapped between the bottom of the transducer  
and the hull of the boat.  
10.Let epoxy cure then the transducer is ready to operate. No water is now required in  
the bottom of the boat and gas and oil that is spilled inside of the boat will not  
degrade performance as it will if the transducer is placed only in water.  
CAUTION: Do not use the silicone seal or any soft adhesive to bond the transducer  
to the hull. This will reduce the sensitivity of the unit.  
CAUTIONS  
1. Occasionally the “eye“ of your transducer may become dirty from storage or from  
contact with oils present in boats or marina environments. (Oil will cause the “eye” to  
lose the intimate contact with the water which is necessary for efficient operation.)  
The “eye” may be cleaned with liquid detergent.  
2. Improper installation of the transducer can alter the efficiency and accuracy of the  
entire system.  
3. If your boat of transducer is out of the water for a period of time, it may take a short  
period of time for the transducer to become thoroughly “wetted” when returned to the  
water. Also, re-entry may cause turbulence, which will create air bubbles in the “eye”  
of the transducer. The bubbles will disappear in a short time or can be removed by  
rubbing the transducer “eye” with your fingers while the transducer is in the water.  
4. If your instrument should fail to function, be sure to check all the electrical  
connections before removing the transducer or calling a serviceman.  
5. Inspect your transducer cable and make sure that it has not been cut or damaged to  
the point where it will affect the performance of the transducer. A slight nick or cut,  
exposing the outer cable, can be repaired by wrapping with electrical tape. A  
transducer can be damaged if the inner cable and outer cable are allowed to make  
contact. Such a problem can sometimes be corrected by properly splicing the  
coaxial cable. This should only be attempted by a qualified service technician.  
6. If your LCR is not working properly and you suspect the problem might be in your  
transducer, we would recommend you borrow a unit from a friend and try it on your  
boat. If the symptoms are the same, you can almost be certain that the problem is in  
the transducer.

INSTALLING THE LCR  
The LCR should be mounted on a flat, solid surface for maximum stability. The low  
profile swivel mount has four holes drilled in the base. It is recommended that all four  
holes be used.  
Position the swivel base and drill four ¼” diameter holes. Note: The LCR hole pattern Is  
the same as for all Humminbird flasher units. Use hardware provided to mount this base  
to the boat.  
Next place the gimbal bracket on the swivel base and attach with four small machine  
screws, provided.  
Place the LCR in the gimbal mount and make certain the rubber washers provided are  
placed between the unit and the gimbal bracket Important: Note which side of the  
gimbal faces forward. (Slots on gimbal bracket go towards rear). Also, rubber washer  
must be located between the unit and the gimbal bracket.  
Install the mounting knobs and tighten snugly. The unit can now be swiveled and tilted  
to any desired position.

OTHER MOUNTING OPTIONS  
1. The LCR gimbal bracket can also be mounted on the SM-4, quick disconnect swivel  
mount.  
2. The LCR gimbal bracket can also be mounted directly to the dash without the swivel  
mount, however, this method is not recommended since the unit cannot be rotated.  
INSTALLING THE CABLES  
Your LCR comes equipped with Humminbird’s new Angle-Lock power and transducer  
connectors. The power connector is identified with the letter P on the back of the plug.  
It plugs into the outlet on the back of the unit marked “Power”. The transducer connector  
is identified with the letter T and plugs into the outlet on the back of the unit marked  
Download from Www.Somanuals.com. All Manuals Search And Download.  
“Transducer”. Note: An adapter (AD-4) is available to allow use of an old waterproof  
(BNC) transducer with the LCR, but be sure that the transducer is a 16degree. A 32-  
degree transducer cannot be used.  
A 11/8” hole must be drilled to pull through the transducer connector. After drilling the  
hole, pull the transducer connector up through the hole. If you are installing two units,  
both transducer connectors can be pulled through this 1 1/8” inch hole. Next, push the  
power cable wires down through the hole. A hole cover has been provided which will  
dress and hold the wires. Install the hole cover after determining the necessary wire  
length from the hole.  
The power cable has a red lead to the positive (+) post and the black lead to the  
negative (-) post. Install a 1 amp fuse between the red cable and positive post of your  
12-volt battery.  
If a fuse panel is available, we recommend wiring the power cable into the fuse panel.  
Note: The LCR must be fused separately from any other accessory.  
Your Angle-Lock connectors can only be plugged in one way. Position the connector so  
the letter P or T can be read and the 90 degree bend is pointed downward. Push the  
connector in as far as it will go. Turn the positive locking ring as far as it will go  
clockwise until you feel it lock. Locking ring as far as it will go clockwise until you feel it  
lock. Your connector is now locked into place.  
Note: For easy access to the connectors, simply loosen the mounting knobs and tilt your  
LCR forward. The connectors are now in full view and easy to plug or unplug.

INSTALLATION  
TEST THE INSTALLATION  
TEST THE INSTALLATION  
Testing should be performed with the boat in the water, however you can initially  
confirm basic operation with the boat trailered.  
Press POWER once to turn the unit on. There will be an audible chirp when any button  
is pressed to confirm the button press. If the unit does not power-up, ensure the unit is  
fully seated on the mount and that power is available.  
The first screen provides four options: Start-up, Options, Simulator, and Diagnostic. A  
message at the bottom of the screen indicates the transducer connection. If no  
transducer is detected (or one is not connected), the message will indicate this and the  
unit will go into simulator after the initial screen times out.  
Note: the transducer must be submerged in water for reliable transducer  
detection.  
If a transducer is detected, the unit will enter “Start Up” or normal operation unless you  
choose another option. If you do not press any button before the timer reaches “0”, the  
normal operation screen is displayed. If the boat is in water, sonar data appears.  
If the bottom is visible on screen with a digital depth readout, the unit is working  
properly. Ensure the boat is in water greater than 2’ but less than the depth  
capability of the unit and the transducer is fully submerged. Remember the sonar signal  
cannot pass through air.  
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. Refer to the appropriate  
transducer installation section for more detail.  
Note: it is often necessary to make several incremental transducer adjustments  
before optimum high-speed performance is achieved.  
Important: For Transom Mount transducer installations, install the third mounting screw  
after the final transducer adjustments.

FEATURES AND FUNCTIONS

USING THE TCR ID-1  
HOW SONAR WORKS  
HOW SONAR WORKS  
Humminbird depth sounders work on the basic principles of sonar. An electronic signal  
generated in the unit is changed to an ultrasonic signal by the transducer or Sensor,  
which sends the signal toward the bottom. The signal travels downward until it strikes  
either the bottom or an object above the bottom. Then, signals or echoes bounce back  
to the Sensor, which receives them and changes them back to electronic signals that  
can be displayed on the unit’s screen.  
Why 455KHz?  
Deepwater depth sounders have long used 50KHz for best deepwater performance, but  
they suffer with poor definition. Shallow-water units use a higher frequeney 200KHz  
system for better target separation and detail. But TCR technology takes high definition  
to a new level with its exclusive 455KHz operation.  
What does that mean to the fisherman? TCRs have twice the frequency, three times the  
power (1600 watts, peak to peak) and twice the detail of other units. You can clearly  
separate fish from the bottom and from structure, and you can see individual fish in a  
way that ordinary depth sounders just can’t show them. Quite simply you see more fish  
with more detail!  
WHAT IS A HIGH-DEFINITION DEPTH SOUNDER?  
The TCR ID-I features our exclusive 455KHz high-definition performance system - twice  
the frequency, three times the power (1600 walls peak to peak) and twice the detail of  
other units.

USING THE TCR ID-1  
HOW SONAR WORKS  
Compact, High-Definition Sensor.  
To send and receive this higher-frequency signal, we developed a new High-Definition  
Sensor. You can immediately see the difference between our 455KHz Sensor and older  
200KHz transducers. This unique new Sensor makes bulky low-definition transducers a  
thing of the past.  
Our new Sensor is so compact, it’s a snap to install. It’s designed for superior high-  
speed performance, and because of its small size you'll have less problem with drag,  
turbulence, or rooster-tails. This new Sensor is actually less likely to be damaged by  
debris, yet performs with all the accuracy you expect from Humminbird.

BUILT-IN SIMULATOR  
BUILT-IN SIMULATOR  
To help you learn to use your new unit, Humminbird has built a simulator into the TCR  
ID-1.The simulator will display a typical underwater scene, and allow you to use the  
controls for practice.  
Activating the simulator is easy - with the unit turned off, hold down the power button for  
about 2 seconds, until a chirping sound begins. When you release the button, the built-  
in simulator will be on and ready for your practice session. Turning your unit off and  
back on again will disengage the simulator, for operating the TCR ID-1 in actual  
conditions.  
NOTE: The built-in simulator will allow you to practice adjusting the sensitivity,  
but your adjustments will not change the readings being displayed on the screen.

USING THE TCR ID-1  
READING THE TCR ID-1 SCREEN  
READING THE TCR ID-1 SCREEN  
Your TCR has a liquid crystal display, or LCD. The liquid crystal material in the display  
aligns itself to either block light or let light pass through. This blocking of light creates  
images on the screen. Since the display depends on light to form its images, increasing  
the light source makes it easier to see. This is why your TCR can be seen so well in  
bright, direct sunlight.  
You will also notice that the display can be seen better at certain angles. The TCR  
mounting system has been designed for tilting and pivoting so that you can easily  
maintain a good angle for viewing. Another characteristic of the display is that some  
polarized glasses can affect your view by causing a rainbow or prism to appear. This  
can be improved by slightly tilting the unit.  
Fish Identification  
The TCR ID-1 uses Humminbird’s exclusive double-layer LCD. Ordinary LCD units have  
2 colors - black and white. But the TCR ID-1 adds a third color - red - by using a second  
layer on the display. This double-layer display gives you more information than ordinary  
black and white units:  
1. Objects close to the bottom are displayed in red. The bottom and any structure  
attached to it are displayed in black. The microcomputer within the TCR ID-1 will detect  
objects close to the bottom and display them in red no matter what depth range you're  
in. This is especially helpful if you're bottom-fishing  
2. Stronger signals are displayed as a black dot behind a red dot. The TCR ID-1's  
microcomputer also helps you identify stronger signals, such as those from larger fish,  
because they are displayed as a black dot behind a red dot. It's easy to separate them  
from the weaker returns displayed in red only.

READING THE TCR ID-1 SCREEN  
Total Screen UpdateÒ  
Humminbird’s exclusive Total Screen Update instantly updates the entire TCR screen to  
include new information each time a function is changed no waiting for the changes to  
“march” onto the screen. This feature is valuable in 2 ways:  
1. Changing depth ranges. When the depth range changes to a deeper or shallower  
scale, the entire screen changes to display the new depth scale. For example, if you’re  
in the 0-60’ scale and it changes to the 0-30’ scale, the entire screen will look as if you  
had been in the 0-30’ range all along.  
2. Using zoom and bottom-lock. Through Pixel Memory Capacity, the memory in the  
TCR ID-1 stores readings in much finer detail than is displayed in the “regular” mode.  
So when you activate the zoom or bottom-lock functions, the entire screen changes to  
display the up-close detail that is stored in memory. Then when you turn on the zoom or  
bottom-lock, the whole screen will change back to the full depth scale.

READING THE TCR ID-1 SCREEN  
Of course, the best way to learn to read your TCR ID-1 is to use it, especially in familiar  
locations. If you know what's underwater and can see it displayed on the screen, then  
you're on your way to being an experienced TCR user.

USING THE TCR ID-1  
OPERATING THE TCR ID-1  
OPERATING THE TCR ID-1  
Your new TCR ID-1 offers unique automatic features, as well as many adjustable ones.  
If you're learning to operate the TCR ID-1 with its simulator, follow the directions listed  
at “Built-In Simulator” on page 16, and then come back to this page. If you’re learning to  
use your TCR ID-1 using actual on-the-water readings, proceed with the following  
instructions.  
Power:  
Pressing this button once turns the TCR ID-1 on. Pressing it once again  
turns it off. When the unit is turned off, holding this button down for about 2  
seconds activates the built-in simulator.  
Stop:  
By pressing this button once, you can stop or “freeze” the display. Pressing  
the button once again re-starts the display at its previous speed setting.  
Light:  
The TCR ID-1 features a 2-level backlight that evenly lights up the display  
from behind the screen. Pressing the “light” button once gives you a soft  
glow that is ideal for night fishing because it won’t interfere with your night  
vision. Press the button again for a brighter light, making the display easy to  
read at dusk when it can be harder to see. Pressing the button a third time  
turns off the backIight.  
Select System:  
The TCR ID-1 Select System commands an amazing number of functions with only four  
buttons: Select, Up and Down arrows, and On/Off.  
When you press the Select button, each function appears in a block on the screen with  
easy-to-understand instructions for using the function. You use the Up and Down  
arrows and the On/Off button to adjust the functions. Then, the Instructions disappear,  
returning the display to its full screen reading.  
Select System functions are “active”; that is, the last function displayed on the screen  
can be adjusted without pressing the select button again. This is valuable in 2 ways.  
Example 1: Readjusting a function.  
If bottom alarm was the last function used, you can adjust it again by pressing one of  
the arrow buttons or the On/Off button.

USING THE TCR ID-1  
OPERATING THE TCR ID-1  
Example 2: Often-used function.  
If you think you'll be using zoom often, you can go to the zoom function, let the  
instructions disappear, and then activate the zoom when you need it simply by pressing  
On/Off.  
The following describes the functions and how to use them,  
in order of appearance after you turn the unit on.  
1. Sensitivity  
Automatic setting: on, "0" or normal  
As conditions change, the computer will automatically in-  
crease or decrease the sensitivity setting. You can manually  
increase or decrease the automatic setting from a range of  
“+5” to “-5.” This level will maintain itself as long as you  
have the unit on, automatically, as a result of the TCR's  
Sensitivity Bias feature. For example, if you set the  
sensitivity at “+2,” the sensitivity will remain 2 settings  
higher than the normal automatic settings until you turn the  
TCR off.  
2. Bottom Alarm  
Automatic setting: off  
Use the On/Off button to activate the alarm, and the alarm  
cursor appears on the screen. Then use the arrow keys to  
adjust the depth at which the alarm will sound. You'll hear a  
continuous chirping sound when the bottom is within the  
area that you've defined with the alarm cursor. This is a  
great feature to use to alert you to shallow  
water, or to maintain your position over structure.  
3. Fish Alarm  
Automatic setting: off  
The fish alarm is easily activated by pressing the On/Off button. This 2-level alarm can  
be set to sound for all fish, or to ignore weaker signals and alarm only for stronger  
signals, such as those from larger fish. You can also adjust the volume of the fish alarm.  
The controls for this function are a little different. Pressing the Up arrow lets you switch  
between alarms for all fish and large fish. The Down arrow controls volume of the alarm.

USING THE TCR ID-1  
OPERATING THE TCR ID-1  
Once the instructions have disappeared from the screen, it's easy to tell which alarm  
you have activated - the alarm for all fish shows both small and large fish symbols at the  
bottom of the screen, while the “large only” alarm displays only a large fish symbol.  
4. Zoom  
Automatic setting: off  
When zoom is activated by pressing On/Off, it creates a “window” of expanded, up-  
close information. This window is marked by a cursor at the right of the screen and can  
be moved up or down with the arrow buttons. The exact depths of the upper and lower  
limits of the window are displayed as depth scales while you are in zoom.  
The size of the zoom window changes as the depth range changes. The window  
displays 7½ feet of up-close readings in the 15’ and 30’ ranges, and 15 feet in the 60'  
and 120’ ranges. Keep in mind that, using your arrow buttons,  
you can move the zoom window while the zoom is activated,  
without having to press Select again.  
5. Bottom-Lock  
Automatic setting: off  
You can easily turn on the bottom-lock with the On/Off button.  
When on, this function shows up-close zoom readings in  
reference to the bottom. The size of the zoom window  
depends on the depth range - 7½ feet in the 15' and 30'  
ranges, and 15 feet in the 60’ and 120' ranges. The zoom  
window will automatically move up or down to stay on the  
bottom, with the cursor showing you the portion of the total  
depth range that is being displayed. This is an ideal feature for  
finding structure or locating fish near the bottom.  
6. Display Speed  
Automatic setting: one setting less than highest speed  
The speed at which the TCR display moves depends on the  
display speed setting, and it is easily changed by pressing the  
Up arrow for a faster setting and the Down arrow for a slower  
setting. Generally speaking, the higher speed settings allow  
faster updates while slower display speeds provide more  
information.

USING THE TCR ID-1  
OPERATING THE TCR ID-1  
7. Depth Range  
Automatic setting: on  
The TCR automatically finds the bottom and then sets and displays the ideal depth  
range when you turn the unit on. If you choose to leave the auto range change on, the  
bottom will remain "blacked in" for easy-to-understand readings, and the depth ranges  
will change automatically.  
Or, you can turn the auto change off, allowing you to change the depth range manually.  
In this mode, the bottom is not blacked in. This lets you see a double bottom echo,  
which is preferred by some fishermen because the width of the second echo can  
indicate bottom texture (see “Reading The TCR ID-I Screen” for details on using the  
double echo).

If the unit comes into contact with salt spray simply wipe the affected surfaces with a  
cloth dampened in fresh water. Do not use a chemical glass cleaner on the lens.  
Chemicals in the solution may cause cracking in the lens of the unit.  
When cleaning the LCD protective lens, use a chamois and non-abrasive, mild  
cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid  
scratching the lens.  
If your boat remains in the water for long periods of time, algae and other marine  
growth can reduce the effectiveness of the transducer. Periodically clean the face of  
the transducer with liquid detergent. Pivoting the transducer up in the bracket may  
allow better access for inspection or cleaning.

If your boat remains out of the water for a long period of time, it may take some time  
to wet the transducer when returned to the water. Small air bubbles can climb to the  
surface of the transducer and interfere with proper operation. These bubbles  
dissipate with time, or you can wipe the face of the transducer with your fingers after  
the transducer is in the water.  
Never leave the fishfinder in a closed car or trunk - the extremely high temperatures  
generated in hot weather can damage the electronics.

TROUBLESHOOTING  
TROUBLESHOOTING  
Do not attempt to repair the fishfinder yourself. There are no user serviceable parts  
inside, and special tools and techniques are required for reassembly to ensure the  
waterproof integrity of the housing. Repairs should be performed only by authorized  
Humminbird technicians.  
Many requests for repair received by Humminbird involve units that do not actually reed  
repair. These units are returned “no problem found.” If you have a problem with your  
Humminbird, use the following troubleshooting guide before calling Customer Support  
or sending your unit in for repair. Your Humminbird fishfinder contains several tools that  
can aid in determining if there is a problem and how to isolate and repair the problem in  
many cases.  
1. Nothing happens when I turn the unit on.  
Check the power cable connection at both ends. Be sure the cable is connected  
correctly to a reliable power source - red lead to positive, black lead to negative or  
ground. Ensure the power available at the mount is between 10 and 20 VDC. If the unit  
is wired through a fuse panel, ensure the panel is powered. Often accessory fuse  
panels are controlled by a separate switch or the ignition switch. Also, often a fuse can  
appear to be good when in fact it is not. Check the fuse with a tester or replace it with a  
fuse known to be good.  
Check the power connection to the unit. It is possible to force the power cable connector  
into the cable holder incorrectly. If the connector is reversed, the unit will not work.  
Examine the contacts on the back of the unit to ensure there is no corrosion. Finally,  
ensure the unit is firmly seated on the mount. The electrical contacts are not made until  
the unit is fully seated.  
Ensure the metal cable retainer is properly installed in the mount. If not, the power  
connected may push out when the unit is put on the mount.  
2. There is no transducer detected.  
Most Humminbird fishfinders have the ability to detect and identify that a transducer is  
connected. If at power up, a message indicates "transducer not connected,” only  
simulator operation is possible. First, ensure that an appropriate transducer connector is  
positioned correctly in the connector holder, and that the unit is fully seated on the  
mount. Your Humminbird fishfinder will work only with an appropriate transducer; check  
the accessory guide for compatibility.

TROUBLESHOOTING  
Second, inspect the transducer cable from end to end for breaks, kinks, or cuts in the  
outer casing of the cable. Also ensure the transducer is fully submerged in water. If the  
transducer is connected to the unit through a switch, temporarily connect it directly to  
the unit and try again. If none of these items identifies an obvious problem, the  
transducer itself is probably the problem. Be sure to include the transducer if returning  
the unit for repair.  
3. There is no bottom reading visible on the display.  
There are a number of possible causes for this condition. If the loss of bottom  
information occurs only at high boat speeds, the transducer needs adjusting. If the  
digital depth readout is working but there is no bottom visible on-screen, it is possible  
the depth range has been adjusted manually to a range lower than what is needed to  
display the bottom. Also, in very deep water, it may be necessary to manually increase  
the sensitivity setting to maintain a graphic depiction of the bottom.  
If you are using a transducer switch to connect two transducers to the unit, ensure the  
switch is in the correct position to connect a transducer that is in water. (If a trolling  
motor transducer is selected and the trolling motor is out of water, no sonar information  
appears.)  
It none of the above solve the problem, inspect the transducer cable from end to end for  
breaks, kinks, or cuts in the outer casing of the cable. If the transducer is connected to  
the unit through a switch, temporarily connect it directly to the unit and try again. If none  
of these items identifies an obvious problem, the transducer itself may be the problem.  
Be sure to include the transducer if returning the unit for repair.  
4. When in very shallow water, I get gaps in the bottom reading and inconsistent  
digital depth indication.  
Your Humminbird fishfinder will work reliably in water 2’ (.6m) or deeper. The depth is  
measured from the transducer, not necessarily from the surface.

5. The unit comes on before I press POWER, and won't turn off.  
Check the transducer cable. If the outer jacket of the cable has been cut and the cable  
is in contact with bare metal, you need to repair the cut with electrical tape. If there is no  
problem with the cable, disconnect the transducer from the unit and see if the problem  
is corrected, to confirm the source of the problem.  
6. I get gaps in the reading at high speeds.  
Your transducer needs adjusting. If the transducer is transom-mounted, there are two  
adjustments available to you - height and running angle. Make small adjustments and  
run the boat at high speeds to determine the effect. It may take several tries to optimize  
high speed operation. This can also be a result of air or turbulence in the transducer  
location caused by rivets, ribs, etc.  
7. My unit loses power at high speeds.  
Most Humminbird fishfinders have over-voltage protection that turns the unit off when  
input voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the  
power output of the engine's alternator and can produce voltage in excess of 20 volts  
when running at high RPMs. Your fishfinder displays input voltage in the Diagnostic  
screen. Use this readout to determine if the voltage exceeds 20 VDC.  
8. The screen begins to fadeout. Images are not as sharp as normal.  
Check the input voltage using Diagnostic. The fishfinder will not operate on input  
voltages below 10 VDC.  
9. The display shows many black dots at high speeds and high sensitivity  
settings.  
You are seeing noise or interference caused by one of several sources. Noise can be  
caused by other electronic devices. Turn off any nearby electronics and see if the  
problem goes away. Noise can also be caused by the engine. If engine noise is causing  
the interference, the problem will intensify at higher RPMs. Increase the engine speed  
with the boat stationary to isolate this cause. Propeller cavitation can appear as noise  
on-screen. If the transducer is mounted too close to the propeller, the turbulence  
generated can interfere with the sonar signal. Ensure that the transducer is mounted at  
least 15" (38cm) from the prop.
