Emergency Operation
An Emergency Alarm is used to indicate a critical situation. You
are able to initiate an Emergency at any time, in any state, even
when there is activity on the current channel.
Your dealer can set the duration of a button press for the
programmed Emergency button, except for long press, which is
similar with all other buttons:
• Short press – Between 0.05 seconds and 0.75 seconds
• Long press – Between 1.00 second and 3.75 seconds
The Emergency button is assigned with the Emergency On/Off
feature. Check with your dealer for the assigned operation of
the Emergency button.
If short press the Emergency button is assigned to turn on the
Emergency mode, then long press the Emergency button is
assigned to exit the Emergency mode.
If long press the Emergency button is assigned to turn on the
Emergency mode, then short press the Emergency button is
assigned to exit the Emergency mode.
Your radio supports three Emergency Alarms:
• Emergency Alarm
• Emergency Alarm with Call
• Emergency Alarm with Voice to Follow
In addition, each alarm has the following types:
• Regular – Radio transmits an alarm signal and shows audio
and/or visual indicators.
• Silent – Radio transmits an alarm signal without any audio or
visual indicators. Radio receives calls without any sound
through the radio’s speaker, until you press the PTT button to
initiate the call.
• Silent with Voice – Radio transmits an alarm signal without
any audio or visual indicators, but allow incoming calls to
sound through the radio’s speaker.
Only one of the Emergency Alarms above can be assigned to
the programmed Emergency button.
