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
• Silent Emergency Alarm
Only one Emergency mode can be assigned to the
Emergency
button.
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.
Contact your system administrator for more information.
