Stopping Automatic Retransmission of Distress Calls
Select CANCEL.
The radio remains tuned to channel 16.
NOTE: Selecting CANCEL ends the automatic repetition of the call, but does not communicate to other
stations that you no longer have an emergency. If you no longer have an emergency, you should revoke the
distress call (
Revoking a Distress Call, page 12
).
Revoking a Distress Call
You do not transmit a distress call until you hold DISTRESS for at least three seconds. If you inadvertently make
a distress call, or are no longer in distress, you should cancel the call immediately by transmitting a voice
message to all stations on channel 16.
1 Select CANCEL > YES, and wait until DISTRESS CANCEL HAS BEEN SENT appears on the screen.
2 Select OK.
3 Hold PTT on the handset, and transmit an appropriate voice message to cancel the distress call (
Call Cancellation Script, page 12
).
4 Select an option:
• Select END to complete the distress-call cancellation and return to normal radio operation.
• Select RESEND to resend the distress-call cancellation and start the process again.
Distress Call Cancellation Script
When you revoke a DSC distress call (
Revoking a Distress Call, page 12
), you should transmit an appropriate
cancellation message.
For example, "All stations, all stations, all stations, this is _____(vessel name), MMSI number ____, position
____(North or South), ____(West or East). Cancel my distress alert of ____(date and time). This is ____(vessel
name), MMSI number ____. Out."
