Using Your Radio
Changing the Volume
To increase the speaker volume, turn the
Volume-Power
knob clockwise; 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 transmissions 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.
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.
