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.

When a channel is set up with a QT tone or DQT code, squelch will only open
when a call containing a matching tone or code is received.  Likewise, signals
that you transmit will only be heard by parties whose QT/ DQT signaling matches
your transceiver.

If a call containing a different tone or code is made on the same channel you are
using, squelch will not open and you will not hear the call.  This allows you to
ignore (not hear) these calls.  Although it may seem like you have your own
private channel while using QT/ DQT, other parties can still hear your calls if they
set up their transceiver with the same tone or code.

You can change the preset encode and decode tones for the selected channel.
Up to 40 tones can be pre-programmed by your dealer.
