Initiating an Emergency Call and Alarm
If the radio has both emergency call and alarm features, it
automatically proceeds to the call mode after the alarm is
acknowledged.
1
Press the emergency button to activate the emergency call/
alarm feature.
The display begins alternating EMERGENCY with the current
zone/channel.
For trunking modes, a high-pitched tone sounds, indicating
that the alarm has been received by the trunked system's
central controller.
A dispatcher acknowledgment (four high-pitched tones) follows,
accompanied by an ACK RCVD display.
2
Press the PTT button and announce your emergency.
3
To exit from the emergency state altogether, press and hold the
emergency button until a tone sounds.
The alternating EMERGENCY display disappears, and the radio
returns to normal operation.
Note: Turning the radio off also cancels the emergency state.
