DSC messages with incorrect format or data may not be received, but it is not a
malfunction. Also if the data terminal is not connected, the equipment does not
receive DSC calls requesting ARQ/FEC communication, regardless of either the
category of routine, safety, urgency or distress.
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 transceiver. Due to the SOLAS Convention (keeping
watch on distress and safety frequencies at all times), do not turn off the
equipment when at sea.
