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:

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.
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.

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.
