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

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, you

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 a

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

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

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 boat’s 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 bot

BEFORE BEGINNING THE HUMMINBIRD ADVANTAGE THE HUMMINBIRD ADVANTAGE The LCR 400ID incorporates the best of available technologies, and offers advantages you won’t 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

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 thro

USING THE LCR400ID 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

USING THE LCR400ID 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
