Thank you for purchasing the Cobra UK 25 LTD ST
CB Radio.Properly used,this Cobra product will
give you many years of reliable service.
SoundTrackerTM
“Cuts noise coming in...strengthens signals
going out.”
This patent-pending technology dramatically
improves transmission and reception of CB
signals.
The revolutionary SoundTrackerTM System recon-
figures the transmission signal,allowing it to be
transferred more efficiently through cluttered air-
waves.
At the same time,it significantly reduces the
amount of static on all incoming CB signals.
The end result is a cleaner,clearer reception of
signals and a more powerful transmission which
dramatically improve CB communications.

Mounting and Connection
Hold the radio with the mounting bracket in
the exact desired location.If there is no inter-
ference,remove the bracket and use it as a
template to mark the location for the mount-
ing screws.
Location
Plan location of transceiver and microphone
bracket before starting the installation.
Select a location that is convenient for operation,
yet does not interferewith the driver or passenger.
The transceiver is usually mounted to the under-
side of the dash with the microphone bracket
beside it.

Ignition Noise InterferenceAntennas
Use of a mobile receiver at low signal levels is
normally limited by the presence of electrical
noise.The primary source of noise in cars is from
the alternator and the ignition system. Typically,
when signal level is adequate,the background
noise does not present a serious problem.Also,
when extremely low-level signals are being
received,the transceiver may be operated with
the vehicle’s engine turned off.The unit requires
very little current and therefore will not signifi-
cantly discharge the vehicle’s battery.
Even though the Cobra UK 25 LTD ST has an auto-
matic noise limiter,in some installations ignition
interference may be high enough to make good
communications impossible.Many possibilities
exist and variations between vehicles require
different solutions.Consult your COBRA dealer or
a 2-way radio technician for help in locating the
source of a severe noise.
CB Antenna
The antenna is critical in affecting transmission
distance.Only a properly matched antenna sys-
tem will allow maximum power output. Cobra
loaded type antenna models are highly recom-
mended for most installations.
Marine Installation
The transceiver will not operate at maximum effi-
ciency in a boat without an earth plate,(unless it
has a steel hull).Before attempting installation ,
consult your dealer for information regarding an
adequate earthing system and prevention of
electrolysis between fittings in the hull and water.

The SoundTrackerTM System
While previous systems only “blanket out”or limit
noise in higher sound frequencies, the revolution-
ary new SoundTrackerTM System actually reduces
noise while leaving the signal intact in the recep-
tion 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 SoundTrackerTM Works
OnReception-“Cutsnoisecomingin”
With a normal CB,distant signals fall below
the squelch level and are unintelligible.With a
SoundTrackerTM 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 reduce the squelch level significant-
ly,which greatly expands your listening range.
OnTransmission-“Strengthenssignalsgoingout”
A SoundTrackerTM 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.

Full clockwise rotation closes the“gate”
allowing only very strong signals to enter.
Full anticlockwise rotation opens the“gate”
allowing all signals in.
To achieve the Desired Squelch Setting (DSS),
turn the Squelch control anticlockwise until
you hear noise. Now turn the control clockwise
until the noise just stops. This is the DSS set-
ting.
