mounting in the manner most convenient for
your installation.
Mounting hardware is supplied for mounting the
Junction Box.The mounting must be mechanically

Connect the antenna cable connector to
the antenna receptacle on the unit. Most CB
antennas are terminated with a type PL-259
plug and mate with the receptacle.
For constant 12 volt source power,connect

positive side ofthe battery or to a connection
on thefuseblock that is always on.

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.
CB Antenna
For the most reliable
operation and maximum
range, Cobra recom-
mends using a vertically
polarized, quarter wave
length whip antenna
(illustration A).
Shorter,loaded-type
whips are adequate when
maximum range is not
required (illustration B)

While previous systems only“blanked out”or
limited noise in higher sound frequencies,the
revolutionary new SoundTracker Systemactually
reduces noise while leaving the signal intact in
thereception mode.In the transmissionmode,it
actually strengthens the signal,providingyou with
a significant reduction innoise on reception and
transmission.
On Reception–
“Cuts Noise Coming In”
With anormal CB,distant signals fall below
thesquelch level andare 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 youto significantly reduce the
squelch level,which greatly expands your
listening range.
OnTransmission–
“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.

Setting the
Squelch
If you turn the squelch control fully counter-
clockwise,it lowers the“squelch gate”so low
that everything gets through - noise, weak
signals and strong signals.
To set the “squelch gate”to the DSS-Desired
Squelch Setting, turn the squelch control
counterclockwise until you hear noise.Then
turn the squelch control back clockwise just
until the noise stops. Now only strong signals
get through.
The Desired Squelch Setting, (DSS) only allows
actual transmissions to come through. This
effectively blocks out unwanted noise.

To achieve the Desired Squelch Setting
(DSS):Think of your Squelch Control as a gate
for incoming signals.If you turn the Squelch
Control fully clockwise, it raises the“squelch

1. Set to channel 9 for emergencies
Be sure antenna is properly connected.
2. CB Distress Data
When transmitting an emergency, you should
request a “REACT BASE”and provide the CB
distress data (called CLIP):
Call Sign Identifyyourself.
Location Beexact.
Injuries Number.Type.Trapped?
Problem Givedetailsandhelpneeded.
TransmitCLIP repeatedly so anymonitor can assist.
• Warn of traffic problems
• Provide weather and road data
• Provide help in event of an emergency
• Provide direct contact with home or office

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
Nation’s population is within listening range
of a NOAA Weather Radio broadcast.
A similar network of about 15 stations using the
same frequencies broadcast continuous weath-
er 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 NationalWeather
Service Office,or write to NationalWeather
Service (Attn:W/OM11),National Oceanic and
Atmospheric Administration,Silver Spring, MD.
