STUN
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. (This function is used when a transceiver is stolen or lost, for example.) Stun is cancelled when the transceiver receives a call with a stun reset code.
DTMF Signalling is either enabled or disabled by your dealer. This function opens the squelch only when the transceiver receives the DTMF code (3 to 10 digits) 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.
Your dealer may also program a Group Code in your transceiver. Ask your dealer for further details.
When you receive a signal containing the correct tones, squelch opens and you will hear the call.
•The LED indicator momentarily flashes orange.
•To mute the speaker after squelch opens, press the key programmed as Monitor or Monitor Momentary.
•Your dealer can program the squelch to close again after a specific time period elapses.
•If Transpond for DTMF Signalling is programmed, an acknowledgment signal is returned to the calling station.
•If Call Alert for DTMF Signalling is programmed, an alert tone will sound when the correct code is received.
