also work.  
CAUTION: Leaving the 75 WX ST on after your car is turned off can  
drain your car battery when connected to a constant 12  
volt source. When connected to accessory 12 volt source

SPEAKERS/NOISE INTERFERENCE  
HOW SOUNDTRACKER WORKS  
12  
13  
EXTERNAL SPEAKER INSTALLATION  
SOUNDTRACKER SYSTEM  
While previous systems only “blanked out” or limited noise in higher  
sound frequencies, the revolutionary new SoundTracker System actually  
reduces noise while leaving the signal intact in the reception mode. In  
the transmission mode, it actually strengthens the signal, providing you  
with a significant reduction in noise on reception and transmission.  
Sound clarity is measured by the ratio of the signal  
level to the noise level. The higher the signal-to-noise  
ratio, the better the sound.  
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.  
1. Mount external speaker in desired location.  
2. Plug jack into the back of the Connector Box labled EXT.  
*The external speaker should have 4-8 ohms impedance and be able to  
handle at least 4 watts.  
IGNITION NOISE INTERFERENCE  
The alternator and ignition system in your vehicle may limit your ability  
to receive low signal levels. Other noise interference can be the result  
of several different installation variables. Consult your Cobra dealer or  
a 2-way radio technician to help locate and correct the source of severe  
noise interference.  
On Transmission “Strengthens Signals Going Out”  
A SoundTracker CB strengthens the transmit signal by more  
effectively using the available RF power output of the CB.The  
result is improved transmission signal clarity and an expanded  
transmission range.

reproduction or carbon or a sales receipt will be required. If you send  
the original receipt it cannot be returned.  
Provide help fast in event of emergency or breakdown.  
Suggest good spots to eat and sleep.  
Make long trips more interesting, and help keep you awake.  
Provide direct contact with your office or home.  
Make friends as you travel.

or exchanged depending on the model. Please allow approximately 3 to  
4 weeks before contacting us for status. If the unit is out of warranty a  
letter will automatically be sent informing you of the repair charge or  
replacement charge. If you have any questions, please call 773-889-3087  
for assistance.  
2. You are not allowed to blast others off the air by overpowering them  
with illegally amplified transmitter power or illegally high antennas.  
3. You cant use the CB to promote illegal activities.

USE CHANNEL 9 FOR EMERGENCY ONLY  
Operating Procedure for Emergency Communications  
1. For EMERGENCY communications, set radio to Ch. 9. For  
WEATHER CHANNEL MESSAGES  
You can receive up to the minute local area weather reports provided by  
NOAA (National Oceanic Atmospheric Administration) 24 hours a day,  
7 days a week. An agency of the U.S. Department of Commerce, NOAA  
warns of dangerous weather, charts our seas and skies, guides our use  
and protection of ocean and coastal resources and conducts research to  
improve our understanding and stewardship of the environment.  
The National Weather Service operates about 380 stations. Approximately  
90 percent of the Nations population is within listening range of a NOAA  
Weather Radio broadcast.  
A similar network of about 15 stations using the same frequencies broadcast  
continuous weather information across much of southern Canada.  
If you have a question concerning NOAA Weather Radio or wish to  
receive a listing of NOAA Weather Radio receiver locations, please  
contact your nearest National Weather Service Office, or write to  
National Weather Service (Attn: W/OM11), National Oceanic and  
Atmospheric Administration, Silver Spring, MD. 20910.  
non-emergency communications, select desired Channel by pressing the  
CHANNEL UP/DOWN tuning buttons until reaching the desired Channel.  
Be sure the antenna is properly connected to the radio before  
transmitting. Prolonged transmitting without an antenna, or use of a  
poorly matched antenna, could cause damage to the transmitter.  
2. When asking for aid on Channel 9 it is suggested that you request a  
REACT base to respond by saying “Break Channel 9 for a REACT base”  
and provide the CB DISTRESS DATA (called “CLIP”):  
CALL SIGN-Identify yourself and vehicle.  
LOCATION-Be exact.  
INJURIES-Number. Type. Trapped?  
PROBLEM- Give details and help required. Air CLIP repeatedly so any  
monitor can aid you.  
If you don't receive a response on Ch. 9; try Ch.14 or 19.  
Note: Some areas may not have a broadcast tower within the receiving

Citizens Band radio operators have largely adopted the “10-code” for  
standard questions and answers. Its use permits faster communications  
and better understanding in noisy areas. The following table lists some of  
the more common codes and their meanings:  
Your COBRA transceiver represents one of the most advanced AM two-
