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...
Page 3
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 type of installation.

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.

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.

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”...

Techsonic Industries, Inc. will not be responsible for any damage due to the mounting of your transducer in this manner. NOTE: An Epoxy Kit (Part N. EPK) is available from Humminbird. This Epoxy Kit has been formulated for Inside Hull Transducer Installation.

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, provided.

Install the mounting knobs and tighten snugly. The unit can now be swiveled and tilted to any desired position.
INSTALLING THE CABLES Your LCR comes equipped with Humminbird’s new Angle-Lock power and transducer connectors. The power connector is identified with the letter P on the back of the plug.
Page 11
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.
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.
Guarantee - free of charge during the first year after your purchase, and available at a reasonable rate after the one-year warranty period. Complete details are provided at the end of this manual. WHAT YOU HAVE Before installing your new LCR 3D, please ensure that the following parts are all included in the product box: Item...
• 1-amp fuse CABLE CONNECTIONS The back of the LCR 3D has a connector for power input, labeled #1, and sensor input, labeled #2. The power and sensor cables supplied with your unit are also labeled. When connecting the cables to your LCR 3D, be sure to orient the alignment guides inside the connectors correctly. It is possible to force the connector together incorrectly.
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.
Page 16
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.
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.
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.
Page 19
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.

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.
SELECT SYSTEM The previous section explains the buttons that let you control the display of screen images. This section shows you how to use the LCR 3D "Select System" to choose from a wealth of useful features and functions. When you press the SELECT button, you see a menu that offers the following functions for further adjustment: •...

3D view unless there are significant differences in operation. 1. Selecting Sensitivity; Factory setting: +0, Digital Filter On The LCR 3D automatically adjusts to the proper amount of sensitivity for conditions (i.e. depth). You can bias the setting + or - 5 levels to suit your personal taste.
Page 23
2. Setting Depth Range; Factory setting: AUTOMATIC 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).
Page 24
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.
Page 25
Units: Feet The LCR 3D lets you customize several aspects of its operation: 1. You can adjust the speed at which display updates. Matching this rate to the speed of your boat provides the most accurate view of the underwater terrain.

LCR 3D. A noticeably weaker signal in one beam than in the others indicates a problem with the sensor location. By comparing readings taken from various inside hull locations to those taken outside the hull relative signal loss, and thus performance, for inside hull mounting can be determined.
Page 27
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:...
