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.

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.
COLOR CODE (CC)
Color Code is a digital signaling for DMR system to enable smooth communication
among groups using the same channel.
