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.
1 Press 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.
2 Release 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.
1 Press 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.
2 To unlock the keys, press and hold the L key again for
more than 0.5 seconds.
