DSC OPERATION

I Distress call

A distress call should be transmitted if, in the opinion of the
Master, the ship or a person is in distress and requires imme-
diate assistance.
NEVER USE THE DISTRESS CALL WHEN
YOUR SHIP IS NOT IN AN EMERGENCY. A
DISTRESS CALL CAN BE USED ONLY WHEN
IMMEDIATE HELP IS NEEDED.
q Confirm any distress call is not being received.
w While lifting up the switch cover, push the [DISTRESS]
switch for 5 sec. to transmit the distress call.
• An emergency channel (Ch 70) is automatically selected and the
distress call is transmitted.
• If no GPS is connected, input your position and UTC time, if pos-
sible.
e After transmitting the call, the transceiver waits for an ac-
knowledgment call on Ch70.
• The distress call is automatically transmitted every 3.5 to 4.5
minutes.
