Instructions for Cancelling Distress Alert

Procedure
VHF DSC

2) Switch equipment on and set to Channel 16.
3) Make broadcast to "ALL Stations" giving your
vessel's name, callsign and DSC number, and
cancel the false distress alert.
DSC MF
1) Switch off equipment immediately.
2) Switch equipment on and tune for radiotele-
phone transmission on 2182 kHz.
3) Make broadcast to "All stations" giving the
vessel's name, callsign and DSC number, and
cancel the false distress alert.
DSC HF
Same as for MF but the alert must be cancelled on all the frequency bands on which it was transmit-
ted. Hence, the transmitter should be tuned consecutively to the radiotelephone distress frequencies
in the 4, 6, 8, 12 and 16 MHz bands, as necessary.
Inmarsat C
Notify the appropriate RCC to cancel the alert by
sending a distress priority message via the same
CES through which the false distress alert was
sent.
EPIRB
If for any reason, an EPIRB is activated accidentally, the ship should contact the nearest coast sta-
tion or an appropriate coast earth station or RCC and cancel the distress alert.
Notes
• Notwithstanding the above, a ship may use any means available to inform the appropriate authori-
ties that a false distress alert has been transmitted and should be cancelled.
• No action will normally be taken against any ship or mariner for reporting and cancelling a false dis-
tress alert. However, in view of the serious consequences of false alert, and the strict ban on their
transmission. Governments may prosecute in cases of repeated violations.
