Emergency Operation
Emergency Alarms are used to indicate critical situations. You can initiate an Emergency Alarm at any
time even when there is activity on the current channel.
You can only assign one type of Emergency Mode to the Emergency button for each channel. Your
radio supports the following Emergency Modes:

Emergency Mode Description
Emergency Alarm

An Emergency Alarm is not a voice call. This alarm is an emergency notifi-
cation sent to radios that are programmed to receive them.
Emergency Alarm
with Call
Your radio transmits an Emergency Alarm. When the Emergency Alarm
is acknowledged, the group of radios can communicate over the assigned
emergency channel. Press and hold the PTT button to talk.
Emergency Alarm
with Voice to Follow
Your radio transmits an Emergency Alarm. When the Emergency Alarm is
acknowledged, your radio microphone is automatically activated which is
known as Hot Mic. Hot Mic allows you to communicate with the group of
radios without pressing the PTT button.
NOTE:
If the Emergency Cycle Mode is enabled, repetitions of Hot
Mic and receiving period are made for a programmed dura-
tion.
If you press and hold the PTT button during the programmed
Hot Mic receiving period, your radio proceeds to make a call
and stops Hot Mic receiving period timer. Your radio remains
in emergency mode. Once PTT button is released, Hot Mic
receiving period timer restarts.
If the Emergency Alarm request fails, the radio does not retry
to send the request, and enters the Hot Mic directly.
