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 (

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 scr

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 the

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

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, remov

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 tran

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

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

“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 t

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, Simulat

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. If after reading the instructions, there is something you do not completely understand about the operations of your unit, we recomme

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. Therefore, the information

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. You will also notice that the red image is transparent, tha

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. How Does Total Screen Update Work? Inside the LCR are memory devices which can store information. Automatic

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. Also, when you go back to the full depth range, the entire screen will be changed to look just as if you had been on that depth range all alon
