The SoundTracker System reduces noise while
leaving the signal intact in the reception mode.
In the transmission mode,it strengthens the sig-
nal,providing you with a significant reduction in
noise on reception and transmission.
How SoundTracker works
On Reception–
“Cuts Noise Coming In”
With a normal CB,distant signals fall below the
squelch level and are unintelligible.With a
SoundTracker CB,the noise level is cut by up to
90%,which increases the signal-to-noise ratio
and dramatically improves signal clarity.This also
allows you to significantly reduce the squelch
level,which greatly expands your listening range.
On Transmission–
“Strengthens Signals Going Out”
A SoundTracker CB strengthens the transmit sig-
nal by more effectively using the available RF
power output of the CB.The result is improved
transmission signal clarity and an expanded
transmission range.

Operating Procedure to Receive
1 . Be sure that power cord, antenna and microphone are connected to the
proper connectors before proceeding further.The weather 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.
6 . Engage the SoundTracker system by depressing the button labeled ST.
Listen to the background noise from the speaker.Turn the SQUELCH CON-
TROL slowly clockwise until the noise JUST disappears (no signal should be
present).Leave the control at this setting.The squelch is now properly
adjusted.The receiver will remain quiet until a signal is actually received.Do
not advance the control too far,or some of the weaker signals will not be
heard.The revolutionary SoundTracker system allows you to reduce
unwanted background noise (static) and increase the signal for better
reception.
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.

Ignition Noise Inte rfe re n c e
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 e vel is adequate,the backg r ound 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 o w level signals are being re ce i ve d,the tra n s ce i ve r
m a y be ope r ated with vehicle engine turned off.
The unit re q u i res ve ry little curre nt and there fo re
will not significa n tly discharge the vehicle bat te ry.
Even though this radio has an auto m a tic noise lim-
i te r,in some installations ignition inte rfe re n c e 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 r re ct i n g
the source of seve re noise.
Te m po ra ry Mobile Ope r at i o n
For te m po ra ry mobile ope rat i o n ,you may wa n t to
p u rchase an additional cigare t te lighter adapte r
f r om 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.

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 & orange wire) has a 2
amp 3AG type fuse in its holder.Use only the
above specified type and size fuse for maxi-
mum 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.

Controls and Indicators
Thank you for purchasing the Cobra 18 WX ST II
CB Radio Transceiver.Properly used,this Cobra
p rod u c t will give you many years of reliable serv i ce.
“Cuts Static coming in,adds Punch going out!”
Technology that dramatically improves the
transmission and reception of CB radio signals.
The revolutionary SoundTrackerTM System recon-
figures the transmission signal which allows it to
be transferred more effectively through cluttered
airwaves.
At the same time,it significantly reduces the
amount of static on all incoming CB signals.
The end result is a clearer,cleaner sounding
reception of signals and a more powerful
transmission which dramatically improve
CB communications.
