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.

activated.  When you have finished operating using OST, press the

turn the OST function OFF.
