EXTERNAL SPEAKER INSTALLATION
1. Mount external speaker in desired location.*
2. Plug jack into the socket marked EXT on the back of the Connector
Box.
*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.

HOW SOUNDTRACKER WORKS

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.
On Tra n s m i s s i on
" S t rengthens 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.
