Monitor

When no signals are present, the squelch on the transceiver automatically
mutes the speaker so you will not hear background noise.
To manually deactivate the squelch, press and hold the Monitor key.
This is useful when you want to adjust the volume level, or when you
need to hear a weak signal.
The LED indicator lights green while the Monitor key is pressed.

Quiet Talk (QT)

Some channels may have pre-programmed QT tones.
A QT tone is a sub audible tone which allows you to ignore (not hear)
calls from other parties who are using the same channel.
When you receive a signal that has a tone different from the one set up in
your transceiver, you will not hear the signal.
Likewise, signals that you transmit will only be heard by parties whose
QT tone matches the tone set up in your transceiver.
Note:
Although using channels set up with QT tones relieves you from listening
to unwanted calls, it does not mean your calls will be private.
