CHAPTER 2 INSTALLATION
INSTALLING THE RADIO
Choose a convenient location for operation that does not interfere with driver 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 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 connected directly to the positive terminal on
the vehicle's battery and the black lead be connected directly to the negative
terminal on the battery. (Note, not connecting both leads direct to the battery may
cause performance problems) 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. It is a good safety
idea to install a second 50 amp fuse that would provide protection in case the red
wire was to "fray" or get pinched and short to the body of the vehicle, somewhere
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.
4.
Mount the microphone bracket near the radio in an easily accessible spot using the
two screws provided.
