Squelch
This controlis used to cut off or eliminate receiver
background noisein theabsence of an incoming
signal. Adjust untilthe receiver noise disappears.
This will require theincomingsignal to beslightly
stronger than average receivernoise.Further clock-
wise rotation will increase the threshold level
which a signal must overcome inorder tobe heard.
Only strong signals will beheard at a maximum
clockwise setting.

CB Antenna
Only a properly matched antenna system will
allow maximum power output.
In mobile installations (cars,trucks,boats,etc.),
an antennasystem that is non-directional should
be used.
When installed in a boat,thetransceiver will not
operate at maximum efficiency without a ground
plate unless the vessel has asteel hull.Before
installing the transceiver in a boat,consult your
dealerforinformation regarding an adequate
grounding system.

Soundtracker
Operation
10
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– “CutsNoiseComingIn”
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.
OnTransmission– “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.
Operation

Ignition Noise Interference
Use of a mobile receiver atlow signal levels isnor-
mally limited by the presence of electricalnoise.
Undermostoperatingconditions,whensignal
levelisadequate,the background noise does not
presenta serious problem.Also,whenextremely
low level signals are being received, the transceiver
may be operated withvehicle engineturnedoff.
The unit requiresvery little currentandtherefore
will not significantly discharge thevehiclebattery.
Even though this radiohas an automatic noise lim-
iter,insomeinstallationsignitioninterference may
be high enough tomakegood communications
impossible.Consult your COBRAdealer ora2-way
radio technician for helpin locating and correcting
the source of severenoise.
TemporaryMobileOperation
Fortemporary mobile operation,youmaywantto
purchase an additional cigarette lighter adapter
fromyourCOBRAdealer.This adapter and a mag-

Maintenance/
Adjustment
Maintenance
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. Make certain the microphone is properly
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.
Permitted:"A tornado sighted six miles of town."
Not Permitted : "This is observation post number 10.
No tornado sighted."

Messages
Replacement Warning
Replacement or substitution of certain parts with
replacements other than those recommended by
Cobra may be a violation of the technical regula-
tions of Part 95 of the FCC rules, or of Type
Acceptance requirements of Part 2 of said rules.
When making adjustments,be sure to re-read
applicable portions of this instruction manual to
makecertain you are following correct procedure
and that the radio was properly installed,etc.
A Few Rules That Should Be Obeyed
1. You are not allowed to carry on a conversation with
another station for more than five minutes at a time with-
out taking a one-minute break to give others a chance to
use the channel.
2. You are not allowed to blast others off the air by overpow-
ering them with illegally amplified transmitter power or
illegally high antennas.
3. You can't use CB to promote illegal activities.
4. You are not allowed to use profanity.
5. You may not play music in your CB.
6. You may not use your CB to sell merchandise or profes-
sional service.
Use Channel 9 For Emergency Messages Only
The FCC gives the following examples of permit-
ted and prohibited types of communications for
use on Channel 9. These are guidelines and are
not intended to be all-inclusive.

Controls and Indicators
Thank you for purchasing the Cobra 18 WX ST II
CB Radio Transceiver.Properly used,this Cobra
product willgive you many years ofreliable service.
“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.
