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 inside the vehicle. In cars, the transceiver is usually mounted below the dash
panel, with the microphone bracket beside it.

MOUNTING THE CONNECTION

The transceiver is supplied with a universal mounting bracket. When mounting the bracket
and radio inside your car, make sure it is mechanically strong. Also provide a good electrical
connection to the chassis of the vehicle. To mount the transceiver, proceed as follows:

1. After you have determined the most convenient location in your vehicle, hold the
transceiver with mounting bracket in the exact location you have chosen. If nothing
interferes 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 CB
antennas are terminated with a PL 259 type 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 broadcast receiver in the car.

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 the two supplied screws. When mounting on a car, place the bracket under the
dash so the microphone is readily accessible.

IGNITION NOISE INTERFERENCE

The use of a mobile receiver at low signal levels is normally limited by the presence of
electrical noise. The primary source of noise in car installations is from the operated
with vehicle engine turned off. The unit requires very little current and therefore will not
signif cantly discharge the vehicle battery. In some installations, ignition interference may
be high enough to make good communications impossible. The electrical noise may come
from several sources. Many possibilities exist and variations between vehicles require
different solutions to reduce the noise.

ANTENNA

A vertically polarized, quarter-wavelength whip antenna provides the most reliable
operation and greatest range. Shorter, loaded-type whip antennas are more attractive,
compact and adequate for applications where the maximum possible distance is not
required. Also, the loaded whips do not present the problems of height imposed by a full
quarter-wavelength whip. Mobile whip antennas utilize the metal body of the vehicle as a
ground plane. When mounted at a corner of the vehicle they are slightly directional, in the
