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 of the Emergency modes can be assigned to the Emergency button or the Emergency
footswitch.
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.
Contact your system administrator for more information.
