SOUNDTRACKER SYSTEM
While previous systems only Òblanked outÓ 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 trans-
mission.
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 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.

Maintenance and Adjustment
Your COBRA CB transceiver is specifically designed for the
environment encountered in mobile installations. The use of
all solid state circuitry and its light weight result in high reli-
ability. Should a failure occur, however, review the follow-
ing, 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 operate your radio.
2. Check the fuse in the DC power cord. The main power
lead (red wire) has a 2 amp 3AG type fuse in its holder.
Use only the above specified type and size fuse for max-
imum protection. Failure to do so, will void the warran-
ty.
3. Make certain the microphone properly plugged in.
4. Make certain the antenna is properly assembled 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.
Replacement Warning
Replacement or substitution of certain parts with replacements
other than those recommended by Cobra may be a violation of
the technical regulations 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 make certain you are
following correct procedure and that the radio was properly
installed, etc.
