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 pages 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.

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 the position data from a distress call can
also be display in the chart application.
When the received distress call is acknowledged by the CRS or
another station then 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 <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>
Message begins
Message received from vessel in distress or details of
the distress

Distress relays sent by other stations
When a Coast Station or another vessel, has received, and
acknowledged a DSC distress alert it may transmit a distress
alert relay to other vessels in the immediate area.
Distress relays sent from other stations can be received by the
radio.
The radio cannot re-send a distress relay automatically. If
required you can relay a distress relay message manually.
If a distress relay is sent specifically to the radio then it can be
acknowledged, otherwise acknowledgement is not required.
