DTMF S
IGNALING
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.
S
TUN
This function is used when a transceiver is stolen or lost.
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.
