Cobra® Classic CB RadioInstallation Instructions
Installation
Location
Installation
Location
Plan location of transceiver and microphone
bracket before starting the installation.
Select a location that is convenient for operation,
yet does not interfere with the driver or passenger.
Note
The transceiver is usually mounted to the underside of the dash with the microphone bracket
beside it.
Mounting and
Connection
Before installing the CB radio,
visually check the vehicle’s battery connection to determine
which terminal, positive or
negative, is grounded (positive
is the larger of the two) to the
engine block (or chassis). A
negatively grounded vehicle
has its negative lead grounded
to the chassis.
Mounting and Connection
1
Note
The transceiver is held in the
universal mounting bracket by
two thumbscrews which allow
for adjustment at a convenient
angle.
Hold the radio with the mounting bracket in
the exact desired location. If there is no interference, remove the bracket and use it as a
template to mark the location for the mounting screws.
3
The bracket includes two selftapping screws and star washers. The mounting must be
mechanically strong, conveniently located.
2
Drill the holes and secure the bracket.
Connect the antenna cable plug to the receptacle marked “ANT” on the back of the unit.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
Installation
Installation
Note
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also permits operating the unit without
running the engine.
6
Plug power cable into back of unit marked
“Power”. Be sure to observe polarity markings.
7
Mount the microphone
bracket on the right side
of the unit (driver’s left)
using two screws supplied. Bracket should be
placed under the dash
so microphone is readily
accessible.
8
Attach the 4-pin microphone cable to
receptacle on the front of the unit and
install unit in bracket securely.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
4
In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
5
Connect the black lead to the negative side of
the vehicle. This is usually the chassis. Any convenient location with a good electrical contact
(remove paint) may be used.

Caution!
Be sure the antenna is properly
connected to the radio before
transmitting. Prolonged transmitting without an antenna, or
a poorly matched antenna,
could cause damage to the
transmitter.
Be sure to read the F.C.C. Rules
and Regulations included with
this unit before transmitting.
