www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com “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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com USING THE LCR INTRODUCTION Before attempting to install or operate your Humminbird LCR, it is recommended that you read the operations manual thoroughly. The LCR4-ID and LCR40-ID have a number of special features not found on other depth sounders. To completely understand all the features of your unit, we suggest you follow the instructions in this manual.
www.reelschematic.com www.reelschematic.com USING THE LCR INTRODUCTION 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.
www.reelschematic.com www.reelschematic.com USING THE LCR INTRODUCTION TheLCR4-ID and LCR40-ID use a special and very unique liquid crystal display. Ordinary LCD's have two colors-black and white. The black color, as was explained earlier, is made by blocking the light that comes into the display. The LCR4-ID and LCR40ID add a third color, red, by using a second layer on the display. If you look closely you will see that the red image is slightly above the black image.
www.reelschematic.com www.reelschematic.com USING THE LCR TOTAL SCREEN UPDATE TOTAL SCREEN UPDATE® What is Total Screen Update? Total screen update is a unique feature of Humminbird LCRs. 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 you’ve already gone over the area.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS 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 the total screen will be updated (changed) to show the zoom information.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS Please read the Theory of Operation in the front of the manual for a detailed explanation of the ID feature. Below are some tips to help you use this advanced ID feature: A. The bottom and anything attached to the bottom are displayed in black. B. Objects at least three inches off the bottom are displayed in red. This makes it very easy to find fish, particularly those close to the bottom. C.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS 4. Automatic or Manual Mode 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 lower left corner of the display any time the unit is in the automatic mode.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS Also, 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 15). 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 16).
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS word Zoom appears in the lower part of the display, indicating that the Zoom is on. You will also notice that the entire screen has been changed to show an expanded view of the area from the top of the Zoom Range to the bottom of the Zoom Range. The LCR'S Total Screen Update feature allows you to zoom in on an area even after you have passed over it.
www.reelschematic.com www.reelschematic.com USING THE LCR 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, you will be seeing up from the bottom and this expanded area will move up or down as the bottom contour changes.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS Automatic Mode: In the automatic mode a continuous alarm will sound only when the bottom depth is equal to or less than the alarm setting. Fish entering the alarm range will not trigger the alarm unless of course the fish alarm is on. Manual Mode: In the Manual Mode either the bottom or fish can trigger the alarm. If the bottom depth becomes equal to or less than the alarm setting, a continuous alarm will sound.
www.reelschematic.com www.reelschematic.com USING THE LCR OPERATIONAL INSTRUCTIONS 9. 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 depth range will automatically be activated. Also, as you move into shallower water the depth range will automatically change to the next smaller scale.
www.reelschematic.com www.reelschematic.com USING THE LCR ADDITIONAL INFORMATION The surface temperature gauge is a valuable fishing and boating aid. It will measure water temperature in one-tenth of degrees and display the reading on the LCR screen. The probe and computer controlled electronics have been designed for an accurate indication and an extremely fast response time. The Trolling Speed Indicator will give very accurate low speed readings, in tenths below 10mph, unlike ordinary speedometers.
www.reelschematic.com www.reelschematic.com USING THE LCR ADDITIONAL INFORMATION CARING FOR YOUR LCR Since your Humninbird 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.
www.reelschematic.com www.reelschematic.com USING THE LCR 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.
www.reelschematic.com www.reelschematic.com USING THE LCR LEARNING TO USE YOUR LCR Step 3 Press the depth set button once to change to the next lowest range. If the bottom is deeper than this range, the computer will automatically change back to the proper range. By pressing the depth set button three or four times you will see that the depth range will change. Next Change to the shallowest range. If the water is deeper than that range the depth range will change to the correct setting.
www.reelschematic.com www.reelschematic.com USING THE LCR LEARNING TO USE YOUR LCR Step 7 Press the Fish Alarm on/off button. Notice the indicator in the lower part of the screen indicating the Fish Alarm is on. Now if an object is detected between the surface and the bottom, a short alarm sound will be heard. By pressing the Fish Alarm on/off button again the Fish Alarm is turned off. Step 8 Steps 1 through 7 have verified that your LCR is working properly.
www.reelschematic.com www.reelschematic.com USING THE LCR LEARNING TO READ THE DISPLAY 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. 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.
www.reelschematic.com www.reelschematic.com USING THE LCR LEARNING TO READ THE DISPLAY Brush or thick standing timber will appear as a thick mass with holes or gaps as shown above. Notice how the strong fish returns (red dots with black behind) can be easily distinguished. 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.
www.reelschematic.com www.reelschematic.com 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.
www.reelschematic.com www.reelschematic.com MAINTENANCE AND WARRANTY 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.
www.reelschematic.com www.reelschematic.com MAINTENANCE AND WARRANTY 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.
www.reelschematic.com www.reelschematic.com MAINTENANCE AND WARRANTY 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.
