Setting mode, press the VOL SQL key again to set the
volume level and return to the main display. There are 16
volume levels - 0 (mute) to 15.

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.
To adjust the squelch level, press and hold the VOL SQL
key. The screen displays SQL and a squelch level number
(0 - 3). Use the ▲ and ▼ keys to adjust the squelch level.
In Squelch Setting mode, press and hold the VOL SQL key
again to set the squelch level and return to the main display.
# 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 ▲ and ▼ keys briefly to scroll through the
channels one channel at a time. Press and hold the ▲ or ▼
key to quickly scroll through the channels.
