FCC regulations permit only “transmission” (one-party to another) rather than
“broadcast” (to a wide audience). Thus, advertising is not allowed on CB channels
because that is “broadcasting”.
FCC Warnings
All transmitter adjustments other than those supplied by the manufacturer as front
panel operating controls, must be made by, or under the supervision of, the holder
of an FCC-issued general Radio-Telephone Operator’s License.
Replacement or substitution of transistors, regular diodes or other parts of a unique
nature, with parts other than those recommended by Cobra, may cause violation of
the technical regulations of Part 95 of the FCC Rules, or violation of Type Acceptance
requirements of Part 2 of the Rules.
You should read and understand Part 95 (included with this unit) of the FCC Rules
and Regulations, before operating your Cobra radio, even though the FCC no longer
requires you to obtain an operator’s license.

External Speaker
The external speaker jack on the rear panel is used
for an External Speaker. The external speaker should
have 8-ohm impedance and be rated to handle at
least 4.0 watts. When the external speaker is plugged
in, the internal speaker is automatically disconnected.
NOTE
Cobra external speakers are rated 15 watts.
Public Address (PA)
An external PA speaker may be connected
to the PA speaker jack when used as a public
address system. The speaker should be directed
away from the microphone to prevent acoustic
feed-back. Physical separation or isolation of
the microphone and speaker must be employed
when operating the PA at high output levels.
Power
These wires supply Power to the CB radio.
This cable is permanently attached to the radio.
If you wish to remove the radio after installation,
disconnect at fuse holder and ground connector.

Turning on Your Mobile Radio
•
Turn the On-Off/Volume knob clockwise to turn
the power on and set the desired listening volume.
CB Antenna
Only a properly matched Antenna system will
allow maximum power output. In mobile installations
(cars, trucks, boats, etc.), an Antenna system that is
non-directional should be used. When installed in a
boat, the transceiver will not operate at maximum
efficiency without a ground plate unless the vessel
has a steel hull. Before installing the transceiver
in a boat, consult your dealer for information
regarding an adequate grounding system.
NOTE
Cobra loaded-type antenna models HGA 1000 and
HGA 1500 are highly recommended for most
installations. Consult your Cobra dealer for further
details (or see order form on page 17).
Three-way combination antennas are available
which allow operation of all three bands (AM-FM
and CB), using a single antenna. However, use
of this type of antenna usually results in less
than normal transmit and receive range when
compared to a standard-type “Single Band”
antenna designed for CB only.
Microphone Connector
Microphone Connector
Allows for convenient removal of the Microphone plug
when storage is required. The Microphone MUST be
connected to the unit at all times, when in use, for

Squelch
This control is used to cut off or eliminate receiver background noise in the absence
of an incoming signal. Adjust until the receiver noise disappears. This will require the
incoming signal to be slightly stronger than average receiver noise. Further clockwise
rotation will increase the threshold level which a signal must overcome in order to be
heard. Only strong signals will be heard at a maximum clockwise setting.
Squelch is the “control gate” for incoming signals.

To squelch your radio:
1. Full clockwise rotation closes the gate,
allowing only very strong signals to enter.
2. Full counterclockwise rotation opens
the “gate,” allowing all signals in.
3. To achieve the Desired Squelch Setting (DSS),
turn the Squelch control counterclockwise until
you hear noise. Now turn the control clockwise
just until the noise stops. This is the DSS setting.

Ignition Noise Interference
Use of a mobile receiver at low signal levels is normally limited by the presence
of electrical noise. Under most operating conditions, 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 vehicle
engine turned off. The unit requires very little current and therefore will not
significantly discharge the vehicle battery.
Even though this radio has an automatic noise limiter, in some installations
ignition interference may be high enough to make good communications
impossible. Consult your authorized Cobra dealer or a two-way radio technician
for help in locating and correcting the source of severe noise.
Temporary Mobile Operation
For Temporary Mobile Operation, you may want to purchase an additional cigarette
lighter adapter from your Cobra dealer. This adapter and a magnetic mount antenna
allow you to quickly “install” your transceiver for temporary use.
Temporary Mobile Operation
NOTE
Red Wire is connected to positive side
of socket center tip. Black Wire is connected
to negative side contacts.
Radio resets to CH 9 when connected to
cigarette lighter plug.
When using the unit with cigarette adapter,
turn off when not in use to avoid draining
the battery.

Prolonged transmitting without an antenna, or with a poorly matched
antenna, could cause damage to the transmitter.
Press-to-Talk Switch
To transmit:
1. Select the desired channel.
2. The receiver and transmitter are controlled by
the Press-to-Talk switch on the microphone.
Press the switch and the transmitter is activated;
release switch to receive. When transmitting
(on a clear channel), hold the microphone
two inches from the mouth and speak clearly
in a normal voice.

Maintenance/Adjustment
Your Cobra CB transceiver is specifically designed for the environment encountered
in mobile installations. The use of all solid state circuitry and its light weight result
in high reliability. Should a failure occur, however, review the following, then if
necessary, replace parts only with identical parts. Do not substitute.
Check Power Source
Check Fuses inDC Power Cord
Check Microphone Connection
Check Antenna Connection
1. Check connections to the source of power
and make sure it is the 13.8 VDC required
to operate your radio.
2. Check the fuses in the DC power cord.
The main power lead (red) has a two amp
3AG type fuse in its holder. Use only the
above specified type and size fuse for
maximum protection. Failure to do so
will void the warranty.
3. Make certain the microphone is properly
plugged in.
4. Make certain the antenna is properly
assembled and connected.
If you are unable to correct the problem,
refer to product service on page 14 for
the correct procedure for warranty and
