SIGNALING
■ 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
/
• Your dealer can set up to 40 tones/codes.
4 Press
to save your new setting.
5 When you have fi nished operating using OST, press the OST key again to
turn the OST function OFF.
■ Radio Access Number (RAN)
RAN is a new signaling system designed for digital radio communications.
When a channel is set up with a RAN, squelch will only open when a call
containing a matching RAN is received. If a call containing a different RAN
is made on the same channel you are using, you will not hear the call. This
allows you to ignore (not hear) calls from other parties who are using the same
channel.
■ Optional Signaling
Your dealer may also program several types of option signaling for your
transceiver channels.
2-tone Signaling: 2-tone Signaling opens the squelch only when your
transceiver receives a call containing matching 2 tones.
DTMF Signaling: DTMF Signaling opens the squelch only when the
transceiver receives a call containing a matching DTMF code.
FleetSync Signaling: Refer to "S
NXDN ID Signaling: NXDN ID is an optional signaling system available only
for digital communications.
