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.
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.
o
Operator Selectable Tone (OST)
If a key has been programmed with [Operator Selectable Tone], you can reprogram
the QT tone or DQT code on each of your channels.
1
Select your desired channel.
2
Press and hold the key programmed as [Operator Selectable Tone].
●
Alternatively, you can press the key programmed as [Menu] to enter OST Mode using
the Menu Mode.
●
The indicator appears on the display.
3
Press the [J] and [K] keys to select your desired tone or code from 1 to 40.
4
Press the [
] key to save your new setting.
After selecting and setting up your desired tone or code, press the [Operator Selectable
Tone] key to activate the OST function. Press this 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 similarly to QT/DQT;
squelch will open when the correct NAC is received.
RADIO ACCESS NUMBER (RAN)
RAN is a 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.
