Turning on the Power
Press and hold the ON/OFF control at the
base or the
[POWER] button on the Remote
SPK/MIC.
Setting the Manual Squelch (base only)
Turn the outer ring of the SQ control at the base to adjust the Squelch.
You must select a channel which is not in use before setting the SQUELCH control.
(see p.19 for “Selecting a Channel”).
Operation
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.
