UNIDEN Model uh089sx UHF CB Radio
Operation
Setting the Squelch
Turn the Unit ON by
rotating the volume control
clockwise. Turn the outer
ring of the control to adjust
the Squelch.
You must select a
channel which is not in use before setting the
SQUELCH control. (see below for "Selecting a Channel").
Think of the squelch
control as a gate. If you
turn Squelch fully
clockwise it raises the
'Squelch gate' so high that
no signals get through.
If you turn the Squelch
fully counterclockwise it
lowers the 'Squelch Gate'
to the extent that all
signals get through -
weak, medium and strong
signals and noise.
To set the 'Squelch Gate'
to the desired level, turn
the squelch knob
counterclockwise until you
hear noise. Then carefully
turn the Squelch knob
clockwise until the noise
fades. Now only strong
signals get through.
Monitor
Press to open the squelch and receive all weak
signals.
Press again momentarily to cancel.
