INSTALLATION

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 driver or passengers in the vehicle. The units location must not
interfere with airbag operation. In automobiles, the transceiver is usually mounted
below 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 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 or
be damaged by the installation of the mounting bolts.
2. Connect the antenna cable plug to the standard receptacle on the rear panel.
Most CB 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 Vdc. This
wire extends from the rear panel. In automobile installation, +13.8 Vdc is
usually obtained from the accessory contact on the ignition switch. This
prevents 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/FM radio in the car. The AM/FM radio power circuit generally has
noise filtering built-in, making it a good place to connect your CB.
4. Connect the black lead to +13.8 Vdc. 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 or near the
transceiver, using two screws supplied. When mounting in an automobile,
place the bracket under the dash so the microphone is readily accessible.
