■ Sending DSC calls (Distress)
A Distress call should be sent if, in the opinion of the captain, the ship or a person is in
distress and requires immediate assistance.
NEVER MAKE A DISTRESS CALL IF YOUR SHIP OR A PERSON IS NOT IN AN

HELP IS NEEDED.

NOTE on Distress calls (Simple calls and Regular calls):
If no valid position data is received when sending a Distress
call, the transceiver waits for 15 seconds until position data
is received, and then the Distress call is sent. If no position
is received during this 15 seconds, the position data in the
transceiver memory is automatically sent. However, if there
is no position data in the memory, the Distress call is sent
without position data.
TIP: A default Distress alert contains:
• Nature of distress: Undesignated distress
• Position information: The latest GPS, or manually input position,
that is held for 4 hours, or until you turn OFF the transceiver.
