DSC OPERATION

■ Making a Distress call

A Distress call should be made if, in the opinion of the Master,

that 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 EMERGENCY. A DISTRESS

CALL SHOULD BE MADE ONLY WHEN IMMEDIATE

HELP IS NEEDED.
