6 Emergency
In case of danger, you can send an emergency alarm / emergency call to ask for help from your
companion or control centre. You can send the emergency call at any time, even when your radio is
in receiving status.
The radio supports the following three emergency alarm modes:
1) Emergency alarm only;
2) Emergency alarm with call;
3) Emergency alarm with voice to follow.
For each emergency mode, there are four emergency status indication types:
1) Alarm only—in emergency mode, emergency alarm tone will sound on the radio.
2) Regular—the radio transmits the emergency alarm, with audio and LED indication.
3) Silent—the radio sends out the emergency alarm, without any audio and the LED indication.
Even when the radio receives the answer, its speaker is mute until the PTT key is pressed.
4) Silent with voice—the radio sends out the emergency alarm and is able to receive an incoming
call, without any audio or visual indicators, until you press the PTT key to initiate, or respond to
the call.
