- The distress acknowledgement is normally sent from a coast station. However
after consulting with the RCC or a coast station and being directed, it is possible
to acknowledge the ship in distress from your own ship.
- After sending the acknowledgement, start communicating with the ship in
distress according to the following procedure.
 Say "MAYDAY".
 Repeat the identity (MMSI) of the ship in distress 3 times
 Say "This is..."
 Repeat the identity (MMSI) of your ship 3 times
 Say "RECEIVED MAYDAY".
- The distress relay calls may be received without receiving the distress alert. In
this case, keep watch the CH16 and handle the message using the displayed
options as appropriate.
