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 w

by rotating up out of the metal spring bracket without harming the transducer, or your boat. The transducer can be re-engaged by simply rotating the transducer down and snapping it back in place. (See Figure A) B. Inside Hull Mount- The high speed transducer can be mounted inside the hull (without pivot assembly) using the proper two-part epoxy, such as Humminbird’s epoxy kit. Even though there is some loss of signal in shooting through the hull, your LCR will perform well with this

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 h

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 or

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 p

wrench provided. The screws are visible through the access holes on each side of the metal bracket. Check to make sure the transducer main body is rigidly fastened to the pivot. (See Figure H) Step 6 CHECK POSITION OF TRANSDUCER- At this point, check to see that the bottom of the transducer is a minimum of ¼” below the bottom of the transom. (However, as noted in STEP 2, the top of the transducer cannot fall below the bottom of the transom). If it is not, remove the transducer assem

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 mot

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.

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 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 transduc

BEFORE BEGINNING There are two main components to a LCR 3D installation: The sensor, which you will install on the transom, and the LCR 3D unit, which you will mount with the supplied gimbal bracket. The sensor and LCR 3D unit communicate by means of a cable, and are powered by your boat's 12- volt DC battery. The sensor and LCR 3D use the basic principles of sonar to reveal objects beneath the water's surface. The LCR 3D uses a four element sensor to transmit a "fan" like signal, which

THE HUMMINBIRD ADVANTAGE The LCR 3D incorporates the best of available technologies, and offers advantages you won't find in other equipment. Three different view options, along with individual beam control, provide a wide array of viewing options. The liquid crystal display (LCD) offers sharp viewing even in bright, direct sunlight, and offers lighting for night operation. Advanced LCD "super-twist" technology built into the LCR 3D offers a wider viewing angle and higher contras

If any item is missing, please see your Humminbird dealer for a replacement or contact Humminbird at our toll-free Customer Service Hotline, listed inside the back cover. In addition to the parts supplied with your LCR 3D, you will need the following for installation and operation: • A drill and drill bits • Phillips-head screwdriver • Flat-head screwdriver • Ruler or measuring tape • Pencil or pen • 12-volt DC power source (your boat's battery) • 1-amp fuse CABLE CON

ACCESSORIES The Trolling Motor Mount adapter, which mounts the sensor on the foot of a trolling motor, gives excellent readings with no interference from the electric motor. Please note, however, that the LCR 3D area of coverage is not round, but elongated side to side. As a result, the display can become disorienting when the trolling motor is turned. Remember that terrain shown on the left of the LCR 3D screen is to the left of the transducer, not necessarily left of the boat. Item

Increase your boat speed to ensure that you get a continuous bottom reading as the boat moves. Your sensor is designed to operate at up to 75 mph, however exercise caution when operating any boat at high speed. If the LCR 3D performs well at idle or slow speeds, but the display is not continuous at higher speeds, the sensor is not installed properly. Air bubbles or turbulence from the boat hull are passing across the sensor face, blocking the transmitted signal. By following the instruc

USING THE BUILT-IN SIMULATOR The LCR 3D 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 3D reading. You can use the simulator to learn the f

WHAT YOU SEE ON-SCREEN The 3-dimensional image you see reflects the way 3-dimensional sonar works. The sonar projects a narrow beam front-to-rear, and a broad beam leftto-right. The LCR 3D interprets the sonar returns to assemble the image displayed on the screen. As you view this image, your boat is at the center of the leading edge, traveling toward the right. What's displayed on the screen is what's immediately behind you. The image is updated constantly as you travel though the w

Right perspective is opposite this, so objects to the right of your boat are shown on the left side of the screen. If your are happy with the factory setting of left perspective, or if you choose to use right perspective, your setting will be remembered by the LCR 3D so that every time you use your unit, the perspective will remain the same until you change it. It is best to try the unit in familiar water to determine which option best suits your needs. The 2D view provides a side vie

Pressing the VIEW button again will display the unique Quad-Beam® view in which all four beams are displayed side by side on-screen. This is similar using four different depth sounders simultaneously, with the sensors aimed in different directions. Pressing the VIEW button again will return you to the 3D view.
