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 radio supports 3 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

visual indicators. There will be no response (call) from the 

target radio until you press the PTT button to initiate the call.

Silent with Voice – Radio transmits an alarm signal and is 
able to receive an incoming call, without any audio or visual 

indicators, until you press the PTT button to initiate, or 

respond to, the call.

Only one of the Emergency Alarms above can be assigned to 
the preprogrammed Emergency button or the Emergency

Emergency footswitch.

acknowledgement, and after all retries have been 
exhausted, a low-pitch tone sounds.

Radio exits the Emergency Alarm mode.
