Emergency Operation
The Emergency feature is used to indicate a critical situation. An emergency signal overrides any other
communication over the selected channel.
Your radio supports the following Emergency modes:
Emergency Alarm
Emergency Call
Emergency Alarm with Emergency Call
One channel supports only one Emergency mode. The radio responds differently when pressing the
preprogrammed Emergency button in each channel.
Your radio is also programmed to operate in one of the following conditions:
Tactical/Non-Revert
The radio sends an emergency alarm and/or makes an emergency call on the current channel.
Non-Tactical/Revert for Conventional System
The radio reverts to the preprogrammed emergency channel to send an alarm and/or make an
emergency call.
Non-Tactical/Revert for Trunking System
The radio reverts to the preprogrammed emergency talkgroup (trunking system) or channel
(conventional system) to send an alarm and/or make an emergency call.
Man Down is an alternate way to activate the Emergency feature. For more information, see Man
Down on page 46.
Contact your system administrator for more information.
