Operation

4.6 DSC call log

Received DSC messages are classified as distress messages and as other messages. The 20
most recent messages for both types are saved in the log.
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
call, follow the instructions of the ship's captain or officer in charge.
Received distress message logs are automatically deleted after 48 hours to
avoid accidental resending or other misoperation. Accordingly, if such
messages cannot be read, it is not a malfunction.
The received distress message logs are cleared when turning off the power
by such as the breaker on the power supply. Due to the SOLAS Convention
(keeping watch on distress and safety frequencies at all times), do not turn
off the equipment when at sea.
