Using the Radio (General Operation)
The following features and settings are available in all bands.
Setting the volume
Turn the VOLUME-POWER knob clockwise to increase the
speaker volume, or counter-clockwise to decrease 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 signals
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.
Changing the channel
Press the CHANNEL UP and CHANNEL DOWN buttons briefly
to scroll through the channels one channel at a time. Press
and hold the CHANNEL UP or CHANNEL DOWN button to
quickly scroll through the channels.
