Installation (Cont.)

3.

Connect the antenna cable plug to the standard receptacle on the unit. Most
CB antennas are terminated with a type PL-259 plug which mates with the
receptacle marked "ANT."

4.

Connect the red lead of DC power cord to +13.8 VDC. In automobile instal-
lations, +13.8 VDC is usually obtained from the accessory contact in the
fuse box. This prevents the set being left on accidentally and also permits
operating the unit without the vehicle's engine running.

Before installing the CB radio, visually check the vehicle battery connec-
tions to determine which battery terminal, positive or negative (positive
is the larger of the two) is grounded to the engine block (or chassis).

5.

Connect he black lead to the negative side of the automobile. This is usual-
ly the chassis of the car. Any convenient location with good electrical con-
tact (remove paint) may be used. Plug power cable into jack on back of
transceiver.

In positive ground automobiles the red wire goes to the chassis and the
black wire is connected to the ignition switch.

6

.

When 13.8 volts DC is initially applied to radio, the radio will turn on
(when power switch is in OFF position) for 1 second. This is the emergency
weather alert normal initialization procedure.

7.

Mount microphone bracket on right side of the transceiver, or near it using
two screws supplied. When mounting in an automobile, place the bracket
under the dash so the microphone is readily accessible.

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 inter-
fere with the driver or passengers in the vehicle. In automobiles, the transceiver
is usually mounted to the underneath of the dash panel, with the microphone
bracket beside it.

Mounting and Connection

The transceiver is held in the universal mounting bracket by two thumbscrews,
permitting adjustment at the most convenient angle.

A universal mounting bracket is supplied along with self tapping screws and
star washers. The mounting must be mechanically strong and also provide a
good electrical connection to the chassis of the vehicle. To mount the transceiv-
er:

1.

Determine the most convenient location in your vehicle, hold the COBRA
radio with mounting bracket in the exact location desired. If nothing will
interfere with mounting it in the desired position, remove the mounting
bracket and use it as a template to mark the location for the mounting
screws.

2.

Drill necessary holes and secure mounting bracket in location.
