LOCATION 
Plan the location of the transceiver and microphone bracket before starting the 
installation. Select a location that is convenient for operation and does not interfere with 
the drive or passengers in the automobiles, the transceiver is usually mounted the dash 
panel with the microphone bracket beside it. 
 
MOUNTING THE RADIO 
The transceiver 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 connection to the chassis of the vehicle. Proceed as follows to mount the 
transceiver: 
 
1.  After you have determined the most convenient location in your vehicle, hold the 
transceiver with mounting bracket in the exact desired location. Before drilling the 
holes, make sure that nothing will interfere with the installation of the mounting 
bracket. 
 
2.  Connect the antenna cable connector to the standard receptacle on the rear panel. 
Most transceiver antennas are terminated with PL-259 male connector which would 
mate with the radio’s connector. 
 
3.  Connect the red DC power input wire (with the fuse) to +13.8V DC. This wire 
extends from the rear panel. In automobile installation, +13.8V DC is usually obtained 
from the accessory contact on the ignition switch. This will prevent the set being left 
on accidentally when the driver leaves the car and also permits operating the unit 
without the engine running.  
 
4.  Connect the black lead to –13.8V DC. This is usually the chassis of the car. Any 
convenient location with good electrical contact may be used. 
 
5.  Mount the microphone bracket on the right side of the transceiver, using the two 
supplied screws.
