Location

Plan the location of the transceiver and microphone brackets before starting the installation.

Select a location that is convenient for operation and does not interfere with the driver or

passengers in the vehicle. In automobiles, the transceiver is usually mounted below the

dash panel, with the microphone bracket beside it.

Mounting

Your mobile 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

connection to the chassis of the vehicle. Proceed as follows to mount the transceiver:

Mount the Transceiver

1.

After you have determined the most convenient location in your vehicle, hold the mobile

radio with the mounting bracket in the exact location desired. If nothing will interfere

with mounting it in the desired position, remove the thumbscrews and use the

mounting bracket as a template to mark the holes for the mounting screws. Before

drilling the holes, make sure nothing behind the surface will be damaged or interfere

with the installation.

2.

Connect the antenna cable plug to the standard receptacle (ANT) on the rear panel.

Most 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 +13.8 V DC. This wire extends

from the rear panel. Connect directly to positive terminal (red) of vehicle's battery.

4.

Connect the black lead to -13.8 V 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 either side of the transceiver, using the two screws

supplied. When mounting in an automobile, place the bracket under the dash so the

microphone is readily accessible.

6.

Attach the microphone cable to the connector on the face of the transceiver.

NOTE 

If power cables need to be shorter, we recommend attaching a 10 amp 

fuse to positive cable (red) at least six inches from vehicle’s battery.
