Receiving a distress call
It is expected that only a Coast Radio Station (CRS)
will acknowledge DSC distress calls and will act as
the coordinator for the rescue operation.
When a distress call is received an alarm is sounded
at full volume and the LCD displays information
relating to the distress.

If the Auto channel change function is enabled; 10
seconds after receipt of a distress call the radio will
automatically re-tune to channel 16. Otherwise the
user is prompted to change channel manually.
The details of the distress call are recorded in the
distress log and the envelope icon will flash to let
you know a message has been received. When
connected to a
Raymarine ® multifunction display
( MFD ) the position data from the distress call can
also be displayed in the Chart application.
When the received distress call is acknowledged by
the CRS or by another station the radio will resume
normal operation.
Ignoring a distress call
You can ignore a distress call by muting the alarm
and cancelling the distress call screen.
If your radio is already tuned to the priority channel
then the
Ignore option will not be available.
With an incoming distress call displayed.
1. Select
Ignore from the options displayed.
Normal operation is resumed.
Acknowledging a distress call
Distress calls must only be acknowledged if the call
continues without acknowledgement from a CRS,
you are close enough to the distressed vessel to
be of assistance and are prepared to relay the
distress to a CRS by any means possible. Class
D DSC radios are forbidden from automatically
acknowledging distress calls. Acknowledgement
must only be made by voice message on channel 16.
After receiving a distress call that has gone
unanswered:
1. Switch to channel 16 to listen for the distress
voice message.
2. Wait for the CRS to acknowledge the call.
3. If the distress call is not acknowledged by another
station then acknowledge the call as follows:

Call sign of the vessel in distress
This is
<MMSI of your vessel>, <name of your
