CTCSS
Setting the FM 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 p.7)
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.
