CAUTION
To turn off an alarm or clear a display such as a received DSC message, do NOT press the
DISTRESS key. Doing so may cause a false distress call.
(Press the CANCEL key to turn off the alarm and delete the on screen message.)
When sending a proxy distress call (DROBOSE), do NOT press the DISTRESS key.
Doing so will inconvenience local shipping and Rescue Centers. (This proxy distress call
can be sent via [Call] button displayed on the screen.)

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.
