CALL PROCEDURE
D When no acknowledgement is received
When no acknowledgement is received the unit will beep
every one second. In this case, the controller automatically
transmits the distress call again every 3.5 to 4.5 minutes.
• A distress relay call may be received after several min-
utes from another ship if acknowledgement cannot be re-
ceived from a coast station directly.
CAUTION: DO NOT push [CLR] while waiting for an ac-
knowledgement, otherwise the distress call repeat will be
cancelled, and a distress acknowledgement is automati-
cally transmitted with your own MMSI.
Use the [CLR] key only when you want to cancel repeated
transmission.
D After receiving an acknowledgement call
The following should be commenced with your voice trans-
mission after receiving a distress acknowledgement from a
coast station (or another ship).
• “MAY DAY”
• “This is .........(your ship name)”
• The 9-digit identity AND the call sign (or other iden-
tification of the ship).
• The ship’s position if the DSC distress does not in-
clude it.
• The nature of the distress and assistance required.
• Any other information which might facilitate the res-
cue.
