■ Quiet Talk (QT)/ Digital Quiet Talk (DQT)
Your dealer may have programmed QT or DQT signaling on
your transceiver channels. A QT tone/ DQT code is a
sub-audible tone/code which allows you to ignore (not hear)
calls from other parties who are using the same channel.
Operator Selectable Tone (OST)
If a key has been programmed with
OST, you can
reprogram the QT/DQT settings on each of your channels.
1 Select your desired channel.
2 Press and hold the key programmed as OST for
1 second.
3 Press / to select your desired tone or code.
• Your dealer can set up to 40 tones/codes.
4 Press to save your new setting.
5 When you have finished operating using OST, press the
OST key again to turn the OST function OFF.
■ Network Access Code (NAC)
Your dealer may have programmed a Network Access
Code on your transceiver channels. NAC is a feature of
P25 transceivers that functions similar to QT/DQT; squelch
will open only when the correct NAC is received.
