Turning on the Power

Turn the radio ON by rotating the Volume/ON/OFF control clockwise.

Setting the Manual Squelch

Turn the SQUELCH control to adjust the Squelch.
You must select a channel which is not in use before setting the SQUELCH control.
(see page 9 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 the desired level, turn
the squelch knob

hear noise. Then carefully
turn the Squelch knob
clockwise until the noise
fades. Now only strong
signals get through.
