Using Your Radio
Setting the volume
Turn the
VOLUME-POWER
knob clockwise to increase the
speaker volume; turn it counter-clockwise to decrease the
volume.
Setting the squelch level
The squelch feature
reduces static on the
speaker by filtering out
any background
channel noise. At the
lowest squelch level,
the speaker plays all
signals, including any
channel noise. Setting
the squelch level higher
filters out noise and lets
only actual radio trans-
missions through.
While listening to a channel, adjust the
SQUELCH
knob until
the noise is filtered and you can hear only the transmission.
If you switch to a channel with a lot of noise or a weak trans-
mission, you may need to readjust the squelch level again.
Note:
Setting the squelch level too high may prevent
you from hearing weaker transmissions. If you are
having difficulty hearing a transmission, try setting the
squelch level lower.
