5.DSC Operation

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.

Note: DO NOT 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.

• Emergency channel (Ch 70) is automatically selected and the

Distress call is transmitted.

• When no GPS is connected, input your position and UTC time, if

possible.

e After transmitting the call, the transceiver waits for an ac-

knowledgment call on Ch 70.

• The Distress call is automatically transmitted every 3.5 to 4.5

minutes.

r When receiving the acknowledgment, reply using the mi-

crophone.
