1. Before attempting to install or operate your Humminbird LCR it is recommended that you read the operations manual thoroughly The LCR is a totally new concept in sonar and has a number of special features not found on any other recorder To completely understand all the features of the LCR we suggest you follow the instructions set forth in this manual If after reading the instructions there is something you do not completely understand about the operations of your unit we recommend you contact aur O stamer Service Department CAL FREE 1 800 633 1468 IMPORTANT Complete your warranty card and return it to us immediately Thank You INTRODUCTION Congratulations on selecting the most advanced piece of sonar equipment ever designed Your new Humminbird LCR Liquid Crystal Recorder incorporates the most advanced innovative concepts in sonar equipment The LCR is probably the most intelligent depth sounder ever created Advanced micro computer technology is used to simplify its operation not complicate it so you can quickly learn the basics of operating your unit After a couple of trips on the water you will be operating your unit like an expert Your Humminbird LCR has a number of outstanding features including a unique automatic feature This computer controlled feature makes using your as simple as pushing the On button The computer will auto matically adjust the sensitivity change the depth scale even if the2. 6 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 assured that the problem is in the transducer WHY DOES THE LCR4000D OPERATE AT 50KHz There are two reasons why the LCR4000D operates at 50KHz Kilo Hertz rather than at 200KHz like the LCR1000 LCR2000 and LCR4000 1 A 50KHz signal will travel farther in water than will a 200KHz signal Since the LCR4000D operates down to 480 feet the 50KHz frequency gives superior depth performance 2 A 50KHz transducer transmits a wider cone angle than an equivalent 200KHz transducer This wider cone angle is especially important in tracking downriggers Since the LCR4000D has a 50KHz receiver and transmitter a 200 2 transducer cannot be used 10 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 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 See Figure 8 Next place the gimbal bracket on the swivel base and attach with four small machine screws provided See Figure 8 Place the LCR in the gimbal mount and make certain the rubbe
