Lowrance LGC-4000 - Baja Installation Manual - Page 2

Tools and Supplies Recommended tools include pliers and a flathead screwdriver. If you need to route the module connector through a bulkhead, you will need a drill and a 7/8" (22 mm) drill bit. If you are mounting the module directly to flat, horizontal surface, you will need a #31 (3 mm) drill bit for the screw holes. Mounting the LGC Module The GPS module can be mounted on any flat surface as long as there is room behind the mounting surface for the screws. The optional pole mount adapter lets you mount the antenna on a pole or swivel mount that uses standard marine 1"-14 threads. CAUTION: Do not mount the GPS module in the direct ! path of a radar antenna's beam. Radar radiates high-energy signals that can interfere with GPS signal reception. Surface Mount The GPS module can be installed on any flat surface that is at least 3-1/2" (90 mm) wide. Make sure a clear, unobstructed view of the sky is available at the selected location. Once you have determined the mounting location, drill the screw holes. The screws supplied with this unit are about 1-1/8" long (4 mm x 30 mm). Drill .120 diameter (3 mm) holes for the mounting screws. If you need to route the cable through the mounting surface, drill a 7/8" (22 mm) hole for the cable's connector. The notch in the antenna housing allows the cable to pass through, if desired, instead of routing it down through the mounting surface. After drilling the holes, pass the O-ring over the cable and press it into the groove on the bottom of the antenna housing. Now attach the antenna to the mounting surface, using 4 mm screws and lock washers. Route the cable to where it connects to the network and plug it in. The installation is complete. 2
