A distress acknowledgement or a distress relay call can be transmitted from a
received distress message stored in the log, but when sending such a kind of call,
follow the instructions of the ship's captain or officer in charge.
In order to avoid accidental distress message treating, received distress messages
will be erased automatically after 48 hours elapsed since the reception.
Accordingly, if such messages cannot be read out, it is NOT a malfunction.
