DTMF SIGNALING
DTMF Signaling is either enabled or disabled by your dealer. This function opens
the squelch only when the transceiver receives the DTMF code programmed in
your transceiver. Each transceiver is normally programmed with a unique code.
You will not hear calls from transceivers that are not programmed with a
matching code.
When you receive a signal containing the correct tones, squelch opens and you
will hear the call.
•The LED indicator flashes orange.
•To mute the speaker after squelch opens, press the key programmed as Monitor.
•Your dealer can program the squelch to close again after a specific time period
elapses.
•If Transpond for DTMF Signaling is programmed, an acknowledgment signal is
returned to the calling station.
•If Tone Alert for DTMF Signaling is programmed, an alert tone will sound when the
correct tones are received.
STUN
This function is used when a transceiver is lost or stolen. When the transceiver
receives a call containing a stun code, either transmit mode will be disabled or
both receive mode and transmit mode will be disabled. Stun is cancelled when
the transceiver receives a call with a revive code.
