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 x5/8 allen head screws, two 3/8 tooth washers and two, 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)
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 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
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 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 its 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.

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 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 Humminbirds 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
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 32degree 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.

THEORY OF OPERATION Your new LCR is covered by our Lifetime Guaranteed Service policy. We wish you good luck, good fishing, and many hours of pleasure with your new Humminbird LCR. THEORY OF OPERATION Your Humminbird LCR works on the basic principals of sonar. An electronic signal is generated within the control head of the unit. When coupled to the transducer, this signal is converted to an ultrasonic signal and is transmitted toward the bottom. The speed of the ultrasonic signal traveling through the waters is approximately 4800 feet per second. The signal travels through the water until it strikes an object or the bottom. At this instant it is reflected back, picked up by the transducer, reconverted to an electronic signal and is recorded on the display of the LCR. The reading at the far right hand position of the display illustrates that which is being passed over at that time. If you are familiar with a flasher unit, you might think of the information coming on the right side of the screen as the information that would be seen at one instant on a flasher (see Figure 1). However, unlike a flasher, this information is not lost but it is shifted or moved to the left as new information comes on. Therefore, the information is retained until it disappears from the left hand position of the display. The display used on the LCR is a Liquid Crystal Display. The material in the display is a liquid that can be aligned such that it either "blocks" light or it lets light pass through. This blocking of light is what makes the dots on the screen. Since the LCRs display depends on light passing through it to make the images, increasing the light source will make it easier to see. This is why your LCR can be seen so well in direct sunlight. You will also notice that the display can be seen better at certain angles. The LCR mounting has been designed for tilting and pivoting so that you can easily maintain a good angle for viewing. Another characteristic of an LCR display is that you may find that some polarized glasses might affect the view by causing a rainbow prism to appear. This condition can possibly be improved by a slight adjustment in tint. The high visibility readout of the LCR allows you to see fish, bottom contour and underwater structure. Targets as close as three inches apart can be separated on the 15 foot setting.

THEORY OF OPERATION The LCR 4000 is designed to operate with a standard 16 transducer included with the unit. Other transducers, such as 32, cannot be used. In order for your LCR to operate well at high speeds, you must have a properly mounted transducer. Please read the transducer mounting procedure carefully.
TOTAL SCREEN UPDATE TOTAL SCREEN UPDATE What is Total Screen Update? Total screen update is a unique feature of the LCR4000. It will allow you, when changing depth scales, to totally change or update the screen to the new depth scale. It will allow you to zoom in and look at information in much finer detail even after youve already gone over the area. It will allow you to reverse or bring back information that has gone off the display (up to three full screens). How Does Total Screen Update Work? Inside the LCR4000 are memory devices which can store approximately 60,000 bits of information. Automatically, while you're operating the LCR4000, the computer is putting information into the LCR'S memory. This stored information is all the data from zero to 120 feet for four entire screens. All this information (from 0 to 120 ft.) is being recorded no matter what depth scale youre using. Also, the information is being put into memory in much smaller increments (pieces) than is being displayed on the normal 0 to 15, 0 to 30, 0 to 60, or 0 to 120 foot scales. For example, on the 0 to 60 foot scale each dot is equal to one foot of depth, but the computer is putting information into memory such that each dot equals 3 inches.
If after reading this, you don't understand all about how the LCR4000s Total Screen Update works, dont worry. The important thing is that you understand how to use Total Screen Update. Read on
TOTAL SCREEN UPDATE How To Use Total Screen Update This is the easiest part. Since the LCRs computer is doing all the work, you will find the LCR4000s Total Screen Update very easy to use. There are three ways that you will use Total Screen Update: 1. When changing a depth scale, the LCRs computer will automatically change or update the entire screen to the new depth scale. In Figure 12 the depth scale is being changed from the 0 to 30 foot scale to the 0 to 60 foot scale. Note that the display was changed to show the entire screen on the 0 to 60 foot scale. This Total Screen Update feature works when changing to shallower scales, too. For example, suppose you are in the 0 to 120 foot scale but the bottom depth is only 10 feet. When you change to the 0 to 15 foot scale, the entire screen will look just as if you had gone over the area on the 0 to 15 foot scale. 2. Total Screen Update allows you to reverse or bring back onto the display three full screens past information. This, in effect, multiplies by four the size of the LCR screen. Operation of the reverse function is explained in a later section. 3. The third way that you will use Total Screen Update is in operating the LCR4000's Zoom. Since the computer has stored in memory information from 0 to 120 feet in very small increments, you will be able to recall this information from memory to get an expanded view of areas which you have already passed over. For example, if you go over some interesting structure or fish, you will be able to zoom in for a better look without going back over the area. Simply activate the zoom and the information that is stored in memory will be recalled and displayed on the screen. The operation of the zoom function is explained in a later section.

OPERATIONAL INSTRUCTIONS OPERATIONAL INSTRUCTIONS FOR LCR4000
The Humminbird LCR4000 will operate fully automatic or manual at the discretion of the operator. At the heart of the LCR is a microcomputer which is making thousands of decisions every second. With the LCR4000'S automatic features you will quickly and easily learn the basics of operating your unit, and after a couple of trips on the water you'll be operating the LCR4000 like an expert. It is suggested that you familiarize yourself with each of the features and controls prior to operating your LCR4000. 1. Power: To activate the unit, depress the power On switch. The LCR4000 always comes on in the automatic mode. In the automatic mode, the unit will find the bottom by varying the sensitivity and selecting the proper depth range for a satisfactory return. Also, the display below the bottom is blacked out to make the display easier to read. To turn the unit off, depress the power Off switch. 2. Depth: In the automatic mode, the proper depth range is found as soon as the unit is turned on. As you move into deeper water and the bottom goes off the screen, the next deeper range will automatically be activated. Also, as you move into shallower water and the bottom is within about ten dots to the top of the screen, the depth range will automatically change to the next shallower scale.
OPERATIONAL INSTRUCTIONS You may also manually change the depth scale by pressing the depth set button. Each time this button is depressed, the range is decreased by one setting. For example, if you are on the 0-30 ft scale, pressing the depth set button once will change the scale to 0-15 ft. Pressing it again will change the scale to 0-120 ft. Note: Should you attempt to change a depth scale which is less than the actual bottom depth, the computer will automatically change the depth scale back to the proper position. For example, if you are in 40 feet of water and you change the depth scale to 30 feet, the computer will automatically change back to the 60 foot scale. Remember, in the manual mode (see paragraph 4 below) the automatic range changer is not active. The depth range is always displayed at the bottom of the LCR display. The LCR4000 has four depth ranges, 0-15, 0-30, 0-60, and 0-120. The graduated depth scales down the left and right of the display will identify the proper depth based upon the range you are on at the time. On the 0-15 scale, each line represents a one foot increment. On the 0-30 scale a two foot increment, on the 0-60 scale, a five foot increment, and on the 0-120 scale, a ten foot increment. Remember that because of the LCR4000s Total Screen Update feature, information is automatically being put into memory in smaller increments (pieces) than is being displayed on the normal depth scales (see explanation of Total Screen Update earlier in manual). This means, for example, that even though you are in the 0 to 120 ft scale, when you change to the 0 to 15 ft scale the information is displayed just as if you had been on the 0 to 15 ft scale all along. No information or resolution is lost. 3. Light: Depress the light On/Off switch to activate the display light for night or low light conditions. The light is turned off by again depressing the ''On/Off'' switch. When using the night light you will notice that the viewing angle, or best viewing position is different than during daylight operation. Tilt the unit back until you find the best angle for night viewing. 4. Sensitivity Automatic Mode- Each time the unit is turned on, the automatic feature is on. In the automatic mode the sensitivity is adjusted automatically to give a good return and the correct depth range is selected. The word Auto will appear in the upper right hand corner of the display any time the unit is in the automatic mode. The sensitivity bar at the top of the screen will increase or decrease automatically indicating the amount of sensitivity being used. In deeper water or soft bottom conditions this bar will increase,

OPERATIONAL INSTRUCTIONS indicating more sensitivity. In shallow water or when a hard bottom is being read, the sensitivity needed to achieve a good return will be less. Also in the automatic mode, the unit will black out the display beneath the bottom line. Manual Mode- There are two ways of putting the LCR4000 in the manual mode: (1) depress the Auto "On/Off" button or (2) depress either sensitivity decrease (-) or increase (+) button. You will notice that the word Auto in the upper right hand corner of the display has gone off. The operator can control the amount of sensitivity by depressing the (+) or (-) button. There are 15 sensitivity settings. When the (+) or (-) button is pressed once, the sensitivity setting at the top of the screen will change by one division. If the (+) or (-) button is held down the setting will move up or down as long as the button is held down. When the maximum or minimum setting is achieved, the unit will make a Chirping" sound indicating a limit has been reached. In the manual mode everything below the bottom is no longer blacked out, therefore a second return or double echo can be displayed if desired. (See Figure 14). Also, the hardness of the bottom can be determined by the thickness of the bottom return. For example, a hard or rock bottom will give a wider bottom return as compared to a soft or muddy bottom. (See Figure 15).
OPERATIONAL INSTRUCTIONS Note: You will find the manual sensitivity control more useful when looking for smaller targets such as smaller fish. In the automatic mode the computer might not be using enough sensitivity to show smaller targets. At higher sensitivity more targets will be seen. Therefore, you might want to use the automatic mode while running and then use the manual mode for charting and finding fish. You should also note that it's possible to have the sensitivity set too high such that reflection off of suspended matter or air bubbles will begin to black out the display. In the manual mode the depth scale does not change automatically and the digital bottom depth is not displayed. To once again activate the automatic mode, depress the Sensitivity Auto On/Off switch. 5. Display: Stop/Resume: Anytime during the operation of the LCR, the operator may freeze the display by simply pushing the display Stop/Resume button. This feature will aid in the learning and interpretation of the signal on your LCR display by giving you time to study the display. The Stop/Resume function will not change any original settings when once again activated. The sensitivity and display speed cannot be changed while the display is stopped. If they are pressed, a chirping sound will indicate that these functions cannot be changed while the display is stopped. All other functions, such as Zoom, Depth Scales, Reverse and Forward, are active with the display stopped. When the Stop/Resume button is pressed again the unit will resume reading at the immediate point at which the boat is sitting on the water. 6. Display Reverse: Information that has gone off the display can be reversed back onto the screen by using the Display Reverses feature. By pressing the Reverse button information that had gone off the left side of the display can be seen again, that is, the display will begin to shift to the right. When the Reverse button is pressed once, the display will move one division to the right. If the button is held down the display will move to the right as long as the button is held down. Up to three full screens may be put back onto the display. Once three screens have been reversed, a chirping sound will indicate that the limit has been reached. 7. Display Forward: This button moves or shifts the display to the left. This means that the Forward button shifts the information in the opposite direction than does the Reverse button. Therefore, the Reverse button shifts the display to the right, and the Forward button shifts the display to the left.

OPERATIONAL INSTRUCTIONS In bottom lock the expanded information always comes onto the screen at the same location. However, as the information moves across the screen and as the bottom contour moves up or down, the displayed information will also move so that you can see the actual bottom contour. Remember, in bottom lock, the bottom always comes on the screen at the same location but then as it moves across the screen it will move up or down as the bottom contour changes. When the bottom lock is activated, the LCR4000 will change to the 120 foot scale, so that the bottom can always be tracked. 9. Display Speed: The LCR4000 has a total of eight display speeds. When the unit is turned on the display will be advancing at a medium speed. To increase the display speed, depress the Fast button once or hold it down to change rapidly. An audible sound is heard each time the speed is advanced. When the limit has been reached a chirping sound will be heard. At this point the speed will be advancing at its maximum. To decrease the speed, simply depress the Slow button until the desired advance is reached. The speed of the boat and the display speed will have a large effect on the way information is displayed. You should select the fastest display speed for high speed operation, but use a slower display speed for idle or trolling speed.
10. Digital Bottom Reading: The digital bottom reading is displayed in the lower left area of the screen. This digital reading will operate while the unit is in the automatic mode, on any depth scale or with zoom or bottom lock activated. The digital bottom reading will not be seen while in the manual mode.
ADDITIONAL INFORMATION Some additional things you should know about the LCR4000. Some polarized glasses might affect your view of the LCR display. It could result in a prism or rainbow effect. This condition can possibly be improved by a slight adjustment in tilt. If you get confused while in the manual mode, for instance, if you don't know where the bottom is, then press the auto on/off button to turn on the automatic mode. The LCR4000 will find the bottom by selecting the proper sensitivity level and depth scale. You can then go back to the manual mode it desired In order for your LCR to operate well at high speeds, you must have a properly mounted transducer. Please read the transducer mounting procedure carefully. The transducer for the LCR4000 is a l6 just like most standard Humminbird flasher units. Other transducers, such as 32, cannot be used. Caring For Your LCR: Since your Humminbird LCR is completely waterproof, it can be cleaned with soap and water or hosed off after salt water use with no fear of damage to the unit or its electronics. When cleaning the lens, it is suggested you use a chamois cloth and a nonabrasive cleaner such as Windex. Do not wipe while dirt or other gritty material is on the lens. Care should be exercised to avoid scratching the lens. Keep chemicals such as bug repellent, ammonia or gasoline away from the LCR case and lens. As with any electrical instrument, do not leave your LCR on the dash board or rear window area of the car. The sun can create extremely high temperatures which can damage the case and internal electrical components. During extended periods of nonuse, such as winter, you should store the LCR and other removable depth sounders in the house or garage. This will help prolong the good appearance and operation of these instruments.

LEARNING TO USE YOUR LCR LEARNING TO USE YOUR LCR After installing the unit, transducer, and power cable as instructed, the LCR is ready for use. By following the steps below you will be able to quickly learn how to use the LCR. Also, trouble shooting suggestions are listed in these steps. Note: Perform steps 1 through 7 at idle or slow speed. These steps will insure that your LCR is working properly. Step 1 Turn your LCR on by pushing the On button. The LCR'S computer will automatically adjust the sensitivity and depth scale so that in about one second you will see images appear on the right side of the display and moving to the left. The small gap in the zero line allows you to see movement on the display even when the bottom is not changing. TROUBLE SHOOTING: If nothing happens when the On button is pushed, check your electrical connections and fuse. Also check that the red wire on the power cable is connected to the positive battery terminal and that the black wire is connected to the negative battery terminal. If these wires are reversed it will not damage the LCR. It is normal if when reversing the boat, the bottom return is lost, since air from the prop is being forced under the transducer. Remember the transducer cannot transmit through air. TROUBLE SHOOTING: If the display comes on when the "On" button is pushed but no bottom information is seen, check that the transducer connector is securely locked to the rear of the LCR. Also insure that the transducer is completely submerged. A transducer cannot work properly in air or through air bubbles in the water. Step 2 Still moving at a slow speed, begin going toward deeper water. You will see that the LCR will display changes as small as 3 inches on the 0-15 foot scale. Continue to move into deeper water until the bottom return moves off the display. The LCR will automatically change to the next deeper depth scale (indicated at bottom of the display). Notice that the entire screen is changed to the new depth scale. This is the Total Screen Update feature.
LEARNING TO USE YOUR LCR Step 3 Press the depth set button once to change to the next lowest scale. If the bottom is deeper than this scale, the computer will automatically change back to the proper scale. By pressing the depth set button three or four times you will see that the depth scale will change down to the 0 to 15 foot scale and then to the 0 to 120 foot scale. Next change to the 0 to 15 foot scale. If the water is deeper than 15 feet, the depth scale will change to the correct scale. Step 4 Press the Stop/Resume button to lock the display. Move the Zoom Range down by holding down the button and position it down to the bottom of the water. Next, activate the Zoom by pressing the Zoom On/Off button. You will see that the entire screen has changed to give you a much more detailed view. Press the Zoom on/off button a few times to go back and forth so that you can get a better understanding of exactly what you are seeing. (You do not have to stop the display to use Zoom, but at first it is probably easier to learn this way). With Zoom on, move the Zoom Range up and down. This is how you can search up and down an entire area. Step 5 Turn the Zoom off. Press and hold down the Reverse button to bring information back onto the screen. As much as three full screens may be reversed. Pressing the Forward button moves the information back to the left. You can also zoom in on the information being reversed. Step 6 Press the Stop/Resume button to begin normal transmitting and receiving. Step 7 Press the Auto Sensitivity On/Off button to change to the manual mode. Notice that the word AUTO in the upper right hand corner of the display has gone off. Also, the area below the bottom is no longer blacked out. You can now change the sensitivity setting by pressing the increase + or decrease - buttons. Notice that the digital bottom reading goes off in the manual mode. Note: in the manual mode the depth scales will not automatically change. The automatic depth change works only in the automatic mode.

LEARNING TO USE YOUR LCR Step 8 Steps 1 through 7 have verified that your LCR is working properly. You are now ready to increase boat speed to test the transducer installation. As you increase boat speed the LCR should give a continuous bottom return. With a proper transducer installation your LCR will perform well at speeds over 75mph. TROUBLE SHOOTING: If at high speeds the bottom return is not continuous or there are gaps in the bottom, then the transducer installation or location is such that air is going under the transducer face. Remember that a transducer cannot work properly through air or through air bubbles in the water. Refer back to the transducer mounting procedure for adjustments or for the other mounting options. TROUBLE SHOOTING: If when making a hard turn, the bottom reading is lost, it is the result of the transducer coming out of the water during the turn. LEARNING TO READ THE DISPLAY The following illustrations show some typical display with bottom, structure, and target returns. These should help you in interpreting the information being displayed on your LCR.
LEARNING TO READ THE DISPLAY
Brush or thick standing timber will appear as a thick mass with holes or gaps as shown above.
Surface clutter: The STC in your LCR will normally eliminate surface clutter, however, in some water conditions or when going across the wake of a boat the surface clutter will appear as shown above.
With Zoom activated the two objects close to the bottom on 0-60 ft scale can now be seen as fish off the bottom. Thermocline is a temperature change at a certain depth in the water. In some conditions the sonar waves will actually reflect or bounce off this temperature change and therefore it will be displayed on the LCR as shown above. To see the thermocline, you will need to go to the manual mode and increase the sensitivity setting. One of the best ways to learn to use your LCR is to go over familiar locations. If you know what's under the water and can see it displayed on the LCR then youre on your way toward gaining the experience you need.

MAINTENANCE AND WARRANTY

MAINTENANCE MAINTENANCE Your Humminbird fishfinder is designed to provide years of trouble free operation with virtually no maintenance. Follow these simple procedures to ensure your Humminbird continues to deliver top performance. 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.

TRANSDUCER MOUNTING PROCEDURE Humminbirds 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 Humminbirds 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
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)
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 x5/8 allen head screws, two 3/8 tooth washers and two, 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)

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 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
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 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 its 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.

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 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 Humminbirds 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
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 32degree 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.

BEFORE BEGINNING

HOW THE LCR400ID WORKS HOW THE LCR400ID WORKS There are two main components to an LCR400ID installation: The transducer, which
you will install on the transom or inside the hull, and the LCR 400ID unit which you will mount with the supplied gimbal bracket. The transducer and LCR 400ID communicate by means of a cable, and are powered by your boats 12-volt DC battery. The transducer and LCR 400ID use the basic principles of sonar to reveal objects beneath the water's surface. The LCR 400ID continuously sends electronic signals to the transducer, which converts them to ultrasonic signals that it aims toward the bottom. Each signal travels downward until it strikes an object or the bottom, then immediately echoes back to the transducer. As the transducer receives these signals, it converts them back to electronic signals for display on the LCR400ID screen.
The LCR 400ID uses the returned signals to display a detailed underwater image, and constantly updates the display as you travel across the water. The display informs you of the current depth and reveals individual fish, schools of fish, their location, and bottom details. Easy-to-use controls on the LCR 400ID allow you to set the depth range, adjust display speed and sensitivity, enable a fish alarm and bottom alarm, and display a "zoom" window of still more detailed information.
THE HUMMINBIRD ADVANTAGE THE HUMMINBIRD ADVANTAGE The LCR 400ID incorporates the best of available technologies, and offers advantages you wont find in other depth sounders. The liquid crystal display (LCD) offers sharp viewing even in bright, direct sunlight, and is continuously lit for nighttime operation. Advanced LCD super-twist technology built into the LCR 400ID offers a wider viewing angle and higher contrast than ordinary LCD screens. (You will notice that the display can be seen better at certain angles. The gimbal mounting bracket lets you easily adjust the viewing angle for optimum viewing. Note also that some polarized glasses can affect your viewing by causing a rainbow or prism to appear; if so, tilt the unit slightly.) Though it includes sophisticated electronics, the LCR 400ID is tough enough to take the pounding punishment of rough seas or a race across the lake. Completely waterproof even saltwater-proof your LCR 400ID will provide you with many years of thoroughly reliable operation. In the unlikely event that your Humminbird does require repairs, we offer an exclusive Service Guarantee free of charge during the first year after purchase, and available at a reasonable rate after the one-year warranty period. Complete details are included in this manual.

USING THE LCR400ID

USING THE BUILT-IN SIMULATOR USING THE LCR400ID This section provides complete information on operating the LCR 400ID through its front panel controls. You are encouraged to read this information completely as you first learn to use the LCR 400ID. Doing so will ensure you make the most of its many features and functions. The first part of this section explains the use of the built-in practice simulator, which you can use to practice selecting functions through the front panel. The remaining instructions, which can be followed while using the simulator or in actual operation, explain each function and are organized according to the front panel layout. USING THE BUILT-IN SIMULATOR The LCR 400ID includes a built-in simulator that helps you learn to use your new equipment. The simulator displays a typical underwater scene, and lets you practice with the controls. The unit must be turned off before you start the simulator. To activate it, press down and hold the POWER button until a chirping sound begins. Release the button, and the built-in simulator begins displaying a typical LCR 400ID reading. You can use the simulator to learn the functions explained in the following pages, just as if you were getting actual on-the-water readings (but note that Sensitivity is disabled). To turn off the simulator, turn off the unit by pressing the POWER button again. Of course, the best way to learn the LCR 400ID is with actual use, especially in familiar waters. If you know whats below and see it on-screen, youll quickly become an LCR 400ID expert.

OPERATING THE LCR400ID FRONT PANEL BUTTONS The LCR 400ID offers several functions that you can adjust with the front panel buttons. (Note that to select something with a button, you must press it fully so that you hear a chirp sound). You can get acquainted with these features by actual operation, or when using the simulator. POWER: Press this once to turn the LCR 400ID on. Pressing it again turns the LCR 400ID off. (Any adjustments you make with the other front panel buttons are retained, as long as the 12-volt DC power supply remains connected). When the unit is off, keeping POWER pressed for about 2 seconds starts the built-in simulator. STOP: Press this to freeze the display so you can study it. Press it again to restart the display movement. SELECT: This button is used to access the following functions for further adjustments: Sensitivity/Units Bottom Alarm Fish Alarm Zoom Bottom Lock Display Speed Depth Range Fish ID
To adjust any of these, press SELECT until the function you want appears. Each functions display tells you how to use the arrow buttons and ON/OFF for adjustment; when first learning, you should also refer to the following instructions. After you adjust any function, the display returns to its full-screen reading. NOTE: The last function you select remains active that is, you can adjust it without having to press SELECT again. You can use this to simplify operations. For example, if the bottom alarm is the last function used, you can readjust the alarm by pressing one of the arrow buttons. Or, if you often use Zoom, you can select it once, then switch it on and off by simply pressing ON-OFF. The following sections describe each function, in order os appearance as you first press SELECT.
OPERATING THE LCR400ID SENSITIVITY 1. Selecting Sensitivity/Units; Factory setting: +0/FEET The Sensitivity/Units function has two uses: It lets you adjust LCR 400ID sensitivity and controls whether depth measurement is in feet or fathoms. The LCR 400ID automatically increases or decreases its sensitivity setting when water conditions change (as when the bottom is stirred up). If you want to manually adjust Sensitivity, select SENS and press the Up or Down arrow button to adjust the automatic setting with a +5 to -5 range. For example, if you set it at +2, Sensitivity remains 2 settings higher than the normal automatic setting. Pressing the ON-OFF button when the SENS menu is displayed switches the unit of depth measurement between feet and fathoms. BOTTOM ALARM 2. Enabling Bottom Alarm; Factory Setting: OFF The Bottom Alarm lets you specify the minimum depth you want to maintain. To use it, select B ALM; then press the ON-OFF button to activate the alarm, and the Up or Down arrow key to adjust the depth at which the alarm will sound. An alarm symbol is displayed when this function is on. When Bottom Alarm is on, youll hear a continuous chirping sound when the bottom is shallower than you defined. This is very handy for alerting you to shallow water or helping you to maintain position over structure.

OPERATING THE LCR400ID FISH ALARM 3. Enabling Fish Alarm; Factory Setting: OFF The Fish Alarm alerts you with a chirping sound whenever the LCR 400ID detects fish (or another object not attached to the bottom). To activate it, select FISH ALM and press the ON-OFF button. A fish symbol reminds you that the alarm is on.
ZOOM 4. Using Zoom; Factory Setting: OFF Zoom provides an up-close view. To activate it, select Zoom and press ON-OFF. The Zoom view initially begins at the surface; pressing the Up or Down arrow adjust the Zoom depth. The range of the display is shown when the Zoom is on. The Zoom range depends on the current Depth Range: 7 in the 15 and 30 Depth Ranges, 15 in the 60 and 120 Depth Ranges, and 30 in the 180 to 600 Depth Ranges. Remember: If Zoom is the last function selected, you can use the arrow button to adjust the Zoom depth or ON-OFF to switch Zoom on and off without having to press SELECT first.
OPERATING THE LCR400ID BOTTOM LOCK 5. Using Bottom-Lock; Factory Setting: OFF Bottom-lock provides an up-close view like Zoom, except that in this case the zoomed view automatically moves up or down to stay on the bottom. To use this feature, select BTM LOCK and press ON-OFF. The range of the display is shown when Bottom-Lock is on. This is an ideal feature for finding structure or Iocating fish near the bottom. Remember: If Bottom-Lock is the last function selected, you can use the ON-OFF button to switch Bottom-Lock on and off without having to press SELECT first.
DISPLAY SPEED 6. Setting Display Speed; Factory Setting: One level below maximum The LCR 400ID display is updated (advances across the screen) as you move through the water. The speed at which the display is updated depends on the Display Speed setting. To adjust it, select SPEED, and press the Up arrow for a faster setting or the Down arrow for a slower setting. In general, higher Display Speed settings provide faster updates, while slower Display Speeds provide more detailed information.
OPERATING THE LCR400ID DEPTH RANGE 7. Setting Depth Range; Factory Setting: On (Automatic) When you turn the LCR 400ID on, it finds the bottom, sets the ideal depth range, and automatically adjusts the depth range (to as much as 480) as the depth changes. In this Auto Depth Range mode, the bottom is blacked-in for easy-to-understand readings. If you prefer, you can turn Auto Depth Range off. Select RANGE, press ON-OFF, and adjust the Depth Range with the Up or Down arrow key. You can set the Depth Range up to 600. In this Manual Depth Range mode, the bottom is not blacked in. This lets you see a second return, which is preferred by some fishermen because the width of the second echo can indicate bottom hardness. FISH ID 8. Selecting Fish ID; Factory Setting: On (Automatic) When you turn the LCR 400ID on, the unit automatically sets Fish ID to the On position. To turn the ID feature off, and display fish with pixels instead of the ID icons, press the ON-OFF button while within the Fish ID menu. Pressing the ON-OFF button again reactivates the ID function.

MAINTENANCE AND WARRANTY

MAINTENANCE MAINTENANCE Your Humminbird fishfinder is designed to provide years of trouble free operation with virtually no maintenance. Follow these simple procedures to ensure your Humminbird continues to deliver top performance. 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.
TROUBLESHOOTING 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.
