Receiving a distress call
When the radio receives a DSC distress call, it:
•
Sounds a two-tone alarm through the handset(s) and speaker(s),
and
•
Automatically switches to channel 16 after 10 seconds if there is
no user intervention.
If the two-tone distress alarm sounds on your radio:
1.
Press the [SILENC] softkey to silence the alert.
You do not need to send a DSC acknowledgement; this will be done
by an official search and rescue station.
2.

from ship and coast stations about the distress.
3.
You can then:
