This radio is supplied with a universal mounting bracket. When mounting the bracket and radio to your car, make sure it is mechanically strong. Also, provide a good electrical grounding connection to the chassis of the vehicle. Proceed as follows to install the radio. 1. Locate a convenient area in your vehicle for the installation of the radio. Hold the mounting bracket with the radio in the location where the radio is to be installed. Make sure nothing will interfere with either the radio or the mounting bolts. Mark and then drill holes for the mounting bracket. 2. Most radio antennas come equipped with a PL-259 plug. Connect this plug to the ANT. Jack in the rear of the radio. 3. Extending from the rear of the radio is a fused red and black wire for the DC connections to the vehicle’s electrical system. For best performance, it is strongly recommended that the red lead be taken directly to the positive terminal on the vehicle’s battery and the black lead be connected to the nearest chassis ground. (Note: This radio is designed for vehicles with negative ground systems.) Connections should be made using appropriate “crimp on” lugs of a size large enough to make good contact with the battery and the chassis ground, It is a second fuse, in series with the red wire at the battery connection. This second fuse would provide protection in case the red wire was to “fray” or get pinched and short to the body of the vehicle, some where between the battery and the radio. High power radios such as require large DC current flow in the TX mode. Poor power can substantially decrease connection is probably important things best transmitter - 3 - - 4 - Installation (Continued) 4. Mount the microphone bracket near the radio in an easily accessible spot using the two screws provided. Ignition Noise Interference With weak signals, you may experience interference of the signal by background noise. This radio has NB and ANL controls which will help reduce background noise from sources such as your ignition system. However, background electrical noise may come from several sources and all noise may not be eliminated. With extremely weak...
