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. 
 

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 location desired. If nothing will 
interfere with mounting it in the desired position remove the mounting bolts. Before 
drilling the holes, make sure nothing will interfere with the installation of the 
mounting bolts. 

 
2.  Connect the antenna cable plug to the standard receptacle on the rear panel. Most 

transceiver antennas are terminated with a type PL-259 plug and mate with the 
receptacle. 

 
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 prevent the set being left on 
accidentally when the driver leaves the car and also permits operating the unit without 
the engine running. Locate the accessory contact on most ignition switches by tracing 
the power wire from the AM broadcast receiver in the car. 

 
4.  Connect the black lead to –13.8V DC. This is usually the chassis of the car. Any 

convenient location with good electrical contact (remove paint) may be used. 

 
5.  Mount the microphone bracket on the right side of the transceiver, using two screws 

supplied. When mounting in an automobile, place the bracket under the dash so that 
microphone is readily accessible.
