DSC OPERATION
■ 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 no distress call is being received.
w While lifting up the switch cover, push [DISTRESS] for 5
sec. to transmit the distress call.
• An emergency channel (Ch 70) is automatically selected and the
distress call is transmitted.
• Input the nature of distress call, if possible. (see p.23 Setting the
distress information)
• When no GPS is connected, input your position and UTC time, if
possible.
e After transmitting the distress call, the transceiver waits for
an acknowledgment call on Ch 70.
•The distress call is automatically transmitted every 3.5 to 4.5
minutes.
r After 5 sec., the transceiver is set to Channel 16 automat-
ically.
