- Switch off the transmitter immediately if the false alert is detected during transmission.
- Now switch on equipment and set to CH – 16.
- Make broad cost to “all stations” giving the ship’s name, call sign, MMSI number and cancel the false distress alert.
All stations (x3)
Name (x3)/ Call sign/ MMSI No.
Cancel my distress alert of date, Time (UTC).
Name of ship/ call sign/ MMSI date/ time (UTC)0
On MF :-
- Switch off transmitter immediately if the false alert is detected during transmission.
- Switch on equipment and set to 2182 kHz.
- Make broadcast to “All stations”, giving the ship’s Name, call sign, MMSI No and cancel the false distress alert.
ON HF :-
We will use same procedure as for MF band, but the alert will be cancelled on all the frequency bands on which the alert was transmitted. The transmitter should therefore be tuned consecutively to the radio telephone distress frequency in the 4, 6, 8, 12 and 16 MHz bands.
- Avoid sending false alerts, the DSC distress alert will be received at greater distances than the cancellation by the wider transmission.
- If the sea area of receiving vessel is not mentioned then assume, vessel (it is in the same area as the alerting vessel).
- Never (Under Any circumstances), attempt to use the DSC equipments to relay a relayed distress alert. Such action can initiate a chain of misleading relays and responses to several RCCs.
