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[...]

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 t ransducer 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 epo[...]

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 slot s. On some aluminum boats it may be necessary to use a wood back - up plate. It is important to use a silicone sealant betwe[...]

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 [...]

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 hea ded pin and insert it through the two parts. Assemble by screwing the ¼”x3/8” allen head screw into the end of the pin a[...]

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 fastene d 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. ([...]

7. Remove the water and transducer and clean the mar ked 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 bott om of the transducer. 9. Coat the bot[...]

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 Humminbird’s ne[...]

It plugs into the outlet on the back of the unit marked “Power”. The transducer connector is identified with the letter T and plugs in to 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 16degre[...]

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 moun t 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 b[...]

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 optio ns, 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 offe[...]

If any item is missing, please see your Hummi nbird 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 dri ll bits • Phillips - head screwdriver • [...]

ACCESSORIES The Trolling Motor Mount ada pter, 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 tu[...]

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 operati ng 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 proper[...]

US ING 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[...]

WHAT YOU SEE ON - SCREEN The 3 - dimensional image you see reflects the way 3 - dimensional sonar works. The sonar proj ects 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, [...]

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 y[...]

Pressing the VIEW butt on 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 agai n will return you to the 3D view. Three sizes of fish symbols are[...]

LCR 3D BUTTON FUNCTIONS The STOP button freezes the display and flashes the digital de pth as a reminder. The Total Sensitivity Updateg feature of the LCR 3D allows you to stop the display, and adjust the sensitivity to provide the best representation of the terrain beneath your boat. Pressing STOP again will restart display movement. The ID button[...]

Note: Press STOP to keep the menus on - screen for a longer perio d of time. To adjust any of these, press SELECT until a menu appears for the function you want. (The list rotates by one choice each time you press SELECT.) As you select a function, on - screen instructions tell you how to use the arrow buttons and ENTE R for adjustment. When first [...]

2. Setting Depth Range; Factory setting: AUTOMAT IC When you turn the LCR 3D on, it finds the bottom, sets the ideal Depth Range, and automatically adjusts the range as the depth changes. In this "Auto Depth Range" mode, the bottom is always displayed for easy - to - understand readings (and AUTO appears at the bottom of the screen). If y[...]

4. Enabling Fish Alarm; Factory setting: OFF The Fish Alarm alerts you with a chirping sound whenever the LCR 3D detects fish (or other objects) above the bottom. You can set it for large fish, large and medium fish, or all fish. To activate it, s elect FISH ALARM and press ENTER. The alarm is initially set for large fish; press the UP or DOWN arro[...]

6. Using Bottom - Lock; Factory setting: OFF Bottom - Lock provides an u p - 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 BOTTOM LOCK and press ENTER. A BL indicator and the range of the display are shown when Bottom - Lock is on. This is an ideal fe[...]

4. The depth readout can be changed from feet to meters. To adjust any of these functions, press ENTER until the black box preceding the function is blacked - in, use the UP and DOWN arrow k eys to adjust the setting, and then press SELECT if no other adjustments are required. 8. Using Diagnostic Factory setting: OFF The Diagnostic function display[...]

The diagn ostic function is also very helpful during troubleshooting to determine where a problem in the system lies. A "weak" beam is usually caused by an improper sensor installation, however, if your sensor is mounted outside the hull, the problem is most likely in the sensor or the LCR 3D itself. Operating Frequency: 455 KHz Power Req[...]
