a c ce s s o ry 12 volt fuse.

5

Co n n e ct the black lead to the negat i ve side of
the auto m o b i l e.This is usually the chassis. Any
co nve n i e nt location with good elect ri cal co nt a ct
( re m ove paint) may be used.

6

Mo u nt the microphone bra c ket on ri g ht side of
the tra n s ce i ver or near it using two scre ws sup-
p l i e d. When mounting in an auto m o b i l e, p l a ce
the bra c ket under the dash so the micro p h o n e
is readily acce s s i b l e.

7

Attach the 4-pin microphone cable to recepta-
cle on front of unit and install unit in bracket
securely.

Mo u nting and Co n n e ct i o n s

Se l e ct a location for the tra n s ce i ver and micro-
phone bra c ket that is co nve n i e nt for ope rat i o n .
In auto m o b i l e s, the tra n s ce i ver is usually mounte d
to the undern e ath of the dash panel, with the
m i c rophone bra c ket beside it.

1

Hold the radio with mounting bra c ket in the
ex a ct location desire d. Re m ove the mount i n g
b ra c ket and use it as a te m p l ate to mark the
l ocation for the mounting scre ws.

2

Drill nece s s a ry holes and secure mount i n g
b ra c ket in locat i o n .

3

Co n n e ct the antenna cable plug to the re ce p t a-
cle marked “A N T” on the back of the unit.

Mounting and
Connections

Note

Before installing the CB radio,

visually check the vehicle bat-

tery connections to determine

which battery terminal, posi-

tive or negative (positive is the

larger of the two) is grounded

to the engine block 

(or chassis).

Mounting and
Connections

Note

The transceiver is held in the

universal mounting bracket by

two thumb screws, permitting

adjustment at the most conve-

nient angle.

A universal mounting bracket

is supplied along with self tap -

ping screws and star washers.

wise ro t ation will increase the threshold leve l
which a signal must ove rcome in order to be heard.
Only strong signals will be heard at a maximum

In mobile installations (ca r s, t ru c k s, bo at s, e tc. ) ,
an antenna sys tem that is non-dire ctional should 
be used.

When installed in a bo at, the tra n s ce i ver will not

Ignition Noise Inte rfe re n ce

Use of a mobile re ce i ver at low signal levels is nor-
mally limited by the pre s e n ce of elect ri cal noise.
Under most ope rating co n d i t i o n s, when signal
l evel is adequate, the backg round noise does not
p re s e nt a serious pro b l e m . Al s o, when ext re m e l y
l ow level signals are being re ce i ve d, the tra n s ce i ve r
m ay be ope rated with vehicle engine turned off.
The unit re q u i res ve ry little curre nt and there fo re
will not significa ntly discharge the vehicle bat te ry.

Even though this radio has an auto m atic noise lim-
i te r, in some installations ignition inte rfe re n ce may
be high enough to make good co m m u n i cat i o n s
i m po s s i b l e. Consult your CO B RA dealer or a 2-way
radio technician for help in locating and co rre ct i n g
the source of seve re noise.

Te m po ra ry Mobile Ope rat i o n

For te m po ra ry mobile ope rat i o n , you may wa nt to
p u rchase an additional cigare t te lighter adapte r
f rom your CO B RA dealer.This adapter and a mag-
netic mount antenna allow you to quickly "install"
your tra n s ce i ver for te m po ra ry use.

Exte rnal Spe a ke r. The External Speaker Jack is
used for an external speaker. The external speak-
er 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.

Powe r : These wires supply power to the CB ra d i o.

Public Ad d re s s : 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 isola-
tion of the microphone and speaker must be
employed when operating the PA at high 
output levels.

Maintenance/
Adjustment

M a i n t e n a n c e

Maintenance and Adjustment

Your COBRA CB transceiver is specifically
designed for the environment encountered in
mobile installations. The use of all solid state cir-
cuitry and its light weight result in high reliabili-
ty. Should a failure occur, however, review the fol-
lowing, then if necessary, replace parts only with
identical parts. Do not substitute.

1 . Check connections to the source of power and

make sure it is the 13.8 VDC required to oper-
ate your radio.

2 . Check the fuses in the DC power cord. The

main power lead (red ) has a 2 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 . Ma ke ce rtain the microphone is pro pe rl y

plugged in.

4 . Make certain the antenna is properly assem-

bled and connected.

If you are unable to correct the problem, refer to
the  SERVICE INSTRUCTIONS at the end of this
manual for the correct procedure for warranty
and post-warranty service from COBRA.

12

Operating Procedure to Receive
1 . 
Be sure that power cord, antenna and microphone are connected to the

proper connectors before proceeding further. The CB/PA switch should
be in the "CB" position.

2 . Turn the radio ON by rotating the  VOLUME CONTROL clockwise.
3 . Rotate SQUELCH CONTROL counterclockwise until incoming signal is

heard.

4 . Select the desired channel.
5 . Set VOLUME CONTROL  to a comfortable listening level.

Operating Procedure 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 micro-
phone two inches from the mouth and speak clearly in a normal voice.

Be sure the antenna is properly connected to the radio before transmit-
ting. Prolonged transmitting without an antenna,or a poorly matched
antenna, could cause damage to the transmitter.
