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.

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.

This feature allows you to send an Emergency Alarm, a non-
voice signal, which triggers an alert indication on a group of 
radios.

Press the programmed Emergency On button.

The LED lights up solid green.

When an Emergency Alarm acknowledgment is received, 
the Emergency tone sounds. The LED blinks green.
