OPERATING FEATURES

MONITORING AN FRS CHANNEL

When you are not receiving a call, the squelch on the
transceiver automatically mutes the speaker so that you will
not hear very weak signals or background noise.
Deactivating this feature to listen to background noise makes
adjusting the volume simpler as well.
1Press and hold the M key for more than 0.5 seconds.
• Squelch is deactivated while you are pressing this key. You
will hear background noise at this time.
2Release the M key to reactivate the squelch.

KEY LOCK

You can lock the MODE key and the switch to prevent
accidentally changing the operating mode, the channel/
station settings, and switching the transceiver OFF.
1Press and hold the L key for more than 0.5 seconds.
• The key lock icon blinks. You can continue to perform
functions in each of the operating modes which does not
involve the MODE key or the switch.
2To unlock the keys, press and hold the L key again for
more than 0.5 seconds.
