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. This includes:
• MMSI or Name of vessel (Name of distressed
vessel is only displayed if it is a contact saved in the
phonebook).
• Nature of distress.
• Latitude and longitude of distressed vessel.
• Time of distress call.

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 on-screen
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.
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:
MAYDAY
(MMSI of the vessel in distress)
Name of vessel in distress
Call sign of the vessel in distress
This is vessel repeated 3 times> RECEIVED MAYDAY 4. You MUST then notify the shore authorities by any means possible to relay the distress call.
