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

Manually relaying a distress call

A distress relay should only be sent if: the person or
vehicle in distress is unable to transmit the distress call
itself, for example red flares sighted at night or the
person or vehicle in distress is out of range of a CRS and
you have already acknowledged the distress by voice
message. You can also relay a received distress relay
alert manually if it goes unanswered.
1. Switch to channel 16
2. Slowly and clearly speak the details of the distress:
MAYDAY RELAY, MAYDAY RELAY, MAYDAY
RELAY
This is <MMSI of your vessel, name of your vessel
repeated 3 times and your call sign>
Received the following MAYDAY from <MMSI of
vessel in distress, name of vessel in distress, call sign
of vessel in distress>
