Location
Plan location of transceiver and microphone

Select a location that is convenient for operation,
yet does not interfere with the driver or passenger.
The transceiver is usually mounted to the underside of the dash with the microphone bracket
beside it.

Note
The transceiver is held in the
universal mounting bracket by
two thumbscrews which allow
for adjustment at a convenient
angle.
The bracket includes two selftapping screws and star washers. The mounting must be
mechanically strong, conveniently located.
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.

Installation
Note
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.
Note
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also permits operating the unit without
running the engine.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.

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.

Note
3-way Combination Antennas
are also available which allow
operation of all three bands
(AM-FM & CB), using a single
antenna. However, this type of
antenna usually results in less
than normal transmit and
receive range when compared
to a standard-type “Single
Band” CB antenna. Call
773.889.3087 for further information.
1
A standard antenna connector is provided
on the transceiver for easy connection.
Marine Installation
The transceiver will not operate at maximum efficiency in a boat without a ground plate, (unless it
has a steel hull). Before attempting installation ,
consult your dealer for information regarding an
adequate grounding system and prevention of
electrolysis between fittings in the hull and water.
6
Ignition Noise Interference
Use of a mobile receiver at low signal levels is
normally limited by the presence of electrical
noise. The primary source of noise in automobiles
is from the alternator and ignition system.
Typically, when signal level is adequate, the background noise does not present a serious problem.
Also, when extremely low level signals are being
received, the transceiver may be operated with
the vehicle’s engine turned off. The unit requires
very little current and therefore will not significantly discharge the vehicle’s battery.
Even though the Cobra 25 NW has an automatic
noise limiter, in some installations ignition
interference may be high enough to make good
communications impossible. Many possibilities
exist and variations between vehicles require
different solutions. Consult your COBRA dealer or
a 2-way radio technician for help in locating the
source of a severe noise.

The CB Story
The Citizens Band lies between the shortwave
broadcast and 10-meter Amateur radio bands,
and was established by law in 1949. The Class D
two-way communications service was opened in
1959. (CB also includes a Class A citizens band
and Class C remote control frequencies.)

FCC Regulations

FCC regulations permit only “transmissions”
(one party to another) rather than “broadcasts”
(to a wide audience). Thus, advertising is not
allowed on CB Channels because that is “broadcasting.”
