■ 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 optional
signaling for your transceiver channels.
5-tone Signaling : Refer to “SELCALL (SELECTIVE
CALLING)” on page 20.
DTMF Signaling : DTMF Signaling opens the squelch only
when the transceiver receives a call containing a matching
DTMF code.
FleetSync Signaling : Refer to “SELCALL (SELECTIVE
CALLING)” on page 17.
NXDN ID Signaling: NXDN ID is an optional signaling
system available only for digital communications.
VOICE OPERATED TRANSMISSION (VOX)
VOX can be activated or deactivated by your dealer. VOX
operation allows you to transmit hands-free.
Note: To operate VOX, you must use an optional headset.
