4.4.3 Distress calls (Distress alerts)
When in distress, distress calls are always transmitted by pressing the dedicated DISTRESS key.
The distress calls transmit own MMSI, ships position, time of the position, and the nature of distress.
CAUTION
Do not test the distress call as doing so will inconvenience local shipping and
Rescue Centers.
When sending a distress call, follow the instructions of the ship's captain or
officer in charge.
If a false distress call is transmitted accidentally, follow the instructions below:
1. Press the CANCEL key on the controller (when appropriate, follow the
commands on screen) and terminate the transmission of the distress call.
2. Report the false distress call to a nearby RCC (Rescue Coordination
Center).
(In Japan, inform the nearest Japan Coast Guard.)
Information to be reported:
The date/time, location, and reason why the false call was transmitted.
Also report the ship's name, type, nationality, ID number as well as the unit
model name and manufacture number/date, if possible.
3. Report the false distress call to nearby ships using CH16.
4. If any acknowledgements to the distress call are received, inform the ships
of the false distress call.
4.4.3.1 Quick distress calls
The following describes the procedure to send a distress call immediately without using menus. In
this case, the nature of distress in the message will be sent as "Undesignated" by default. Further, if
no information for the position and the time of position obtained within 23.5 hours, these information
will be composed automatically as "9999999999" and "8888" respectively.
