39SIGNALINGQuiet tAlk (Qt)/ digitAl Quiet tAlk (dQt)Your dealer may have programmed QT or DQT signaling onyour transceiver channels. A QT tone/ DQT code is asub-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, squelchwill only open when a call containing a matching tone or code isreceived. Likewise, signals that you transmit will only be heardby parties whose QT/ DQT signaling matches your transceiver.If a call containing a different tone or code is made on thesame channel you are using, squelch will not open and you willnot hear the call. This allows you to ignore (not hear) thesecalls. Although it may seem like you have your own privatechannel while using QT/ DQT, other parties can still hear yourcalls if they set up their transceiver with the same tone or code.■ operAtor SelectABle tone (oSt)If a key has been programmed with OST, you canreprogram the QT/DQT settings on each of your channels.1 Select your desired channel.2 Press and hold the key programmed as OST for second.• The icon appears on the display.3 Press the / keys to select your desired tone orcode.
