Sending a Silent Emergency Alarm

This feature allows you to send an Emergency Alarm to another
radio without any audio or visual indicators.
Upon acknowledgement, your radio's microphone is
automatically activated, allowing you to communicate with the
other radio without pressing the PTT button.
This activated microphone state is also known as "hot mic".
If you press the PTT button during the preprogrammed hot mic
transmission period, the radio ignores the PTT press and
remains in Emergency mode.
Note: If you press the PTT button during hot mic, and
continue to press it after the hot mic duration expires,
the radio continues to transmit until you release the
PTT button.
Procedure:
1
Press the preprogrammed Emergency button.
2
The display shows no changes, the LED does not light up,
and you hear no tones.
3
The silent emergency state continues until you:
Press and hold the preprogrammed Emergency button for
about a second to exit the Silent Emergency Alarm mode.
OR
Press and release the PTT button to exit the Silent
Emergency Alarm mode and enter regular dispatch or
Emergency Call mode.
Note: For ALL Emergency signals, when changing channels:
•
If the new channel is also preprogrammed for
Emergency, you can change channels while in
Emergency operation. The emergency alarm or call
continues on the new channel.
•
If the new channel is NOT preprogrammed for
Emergency, the display shows No emergency, and
you hear an invalid tone until you exit the Emergency
state or change to a channel preprogrammed for
Emergency.
