User manual HUMMINBIRD LCR 4X6

[. . . ] Before attempting to install or operate your Humminbird LCR it is recommended that you read the operations manual thoroughly. The LCR has a number of special features not found on any other depth sounder. Therefore, to completely understand all the features we suggest you follow the instructions in this manual. If, after reading the instructions, there is something you do not completely understand about the operation of your unit, we recommend you contact our Customer Service Department-CALL 334-687-0503 Our Customer Service hours are Monday- Friday 8:00 A. [. . . ] If your instrument should fail to function, be sure to check all the electrical connections before removing the transducer or calling a serviceman. 5. 6. Inspect your transducer cable and make sure that it has not been cut or damaged to the point where it will affect the performance of the transducer. A slight nick or cut, exposing the outer cable, can be repaired by wrapping with electrical tape. A transducer can be damaged if the inner cable and outer cable are allowed to make contact. Such a problem can sometimes be corrected by properly splicing the coaxial cable. If your LCR is not working properly and you suspect the problem might be in your transducer, we would recommend you borrow a unit from a friend and try it on your boat. If the symptoms are the same, you can almost be certain that the problem is in the transducer. INSTALLING THE LCR The LCR should be mounted on a flat, solid surface for maximum stability. Position the swivel base and drill four ¼" diameter holes. Note: The LCR hole pattern Is the same as for all Humminbird flasher units. Next place the gimbal bracket on the swivel base and attach with four small machine screws, provided. Place the LCR in the gimbal mount and make certain the rubber washers provided are placed between the unit and the gimbal bracket Important: Note which side of the gimbal faces forward. Also, rubber washer must be located between the unit and the gimbal bracket. 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. 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 Angle-Lock power and transducer connectors. The power connector is identified with the letter P on the back of the plug. 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 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. Install the hole cover after determining the necessary wire length from the hole. The power cable has a red lead to the positive (+) post and the black lead to the negative (-) post. [. . . ] Next, push in the button for one to two seconds, until you hear the chirping sound. It should be noted, however, that increasing or decreasing the sensitivity setting will not affect the information being displayed. CARING FOR YOUR LCR: Since your Humminbird LCR is completely waterproof, it can be cleaned with soap and water or hosed off after salt water use with no fear of damage to the unit or its electronics. When cleaning the lens, it is suggested you use a chamois cloth and a non-abrasive cleaner such as Windex Do not wipe while dirt or other gritty material is on the lens. Keep chemicals such as bug repellant, ammonia or gasoline away from the LCR case and lens. [. . . ]
