will be emitted if the radio is programmed to do so.

Press and hold the button to initiate an Emergency Alarm mode.
Once Emergency Alarm is initiated, the emergency message is transmitted 

automatically. The radio will emit a series of beeps and "EMERGENCY" will flash 

on the display. "EMERGENCY" and the incoming P25 ID or MDC number or label 

will be displayed on the receiving radio. An alert tone will be emitted if the radio is

When the emergency alarm is broadcast for digital operation, the radio 

will not receive the signal while a scan is active (Priority, Channel, Zone) unless 

the following conditions are met: 1) the Data Mode for the Emergency Channel of 

the TX Radio (radio declaring the emergency) needs to be Repeated or Direct (not 

FNE); and 2) the Data Scan Hold Time on RX radios needs to be non-zero. Analog 

channels will work while scanning without any special settings on either radio.
