Chapter 2 Installation
Installing the Radio
Choose a convenient location for operation that does not interfere with drive or passenger. 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
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 bolt used to fasten to the battery and the chassis ground, It is a good safety idea to install 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 this one require large DC current flow when in the TX mode. Poor power connections cause supply voltage drops that can substantially decrease the performance of your radio. A good DC connection is probably one of the most important things for getting the best transmitter performance and in some cases, least receiver noise.
