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.
