The radio returns to the Home screen.
If your radio is set to Silent, it does not display any audio or 
visual indicators during Emergency mode, or allow any received 
calls to sound through the radio’s speaker, until the 
programmed hot mic transmission period is over, and you press 
the PTT button.
If your radio is set to Silent with Voice, it does not display any 
audio or visual indicators during Emergency mode when you 
are making the call with hot mic, but allow sound through the 
radio’s speaker when the target radio responds after the 
programmed hot mic transmission period is over. The indicators 
only appear when you press the PTT button.
NOTE: If the Emergency Alarm request fails, the radio does 
not retry to send the request, and enters the hot mic 
state directly.
Reinitiating an Emergency Mode
NOTE: This feature is only applicable to the radio sending the 
Emergency Alarm.
There are two instances where this can happen: 
You change the channel while the radio is in Emergency 
mode. This exits the Emergency mode. If Emergency Alarm 
is enabled on this new channel, the radio reinitiates 
Emergency.
You press the programmed Emergency On button during an 
Emergency initiation/transmission state. This causes the 
radio to exit this state, and to reinitiate Emergency.
