3. DSC DISTRESS OPERATIONS
How to transmit a distress acknowledge call over CH16
Transmit the distress acknowledge call
to the ship in distress over DSC CH70.
Relay the distress alert to a coast station over DSC.
Follow the instructions of the coast station.
Begin search and rescue operation for the ship in distress.
Procedure when in area A1
When you receive a distress alert from a ship in distress, the audio alarm sounds and
the LED flashes in red. The icon for DISTRESS receiving (
and the pop-up message "DISTRESS ALERT message received! [CANCEL]: Stop
alarm" appears on the screen.
Press the CANCEL key to silence the audio alarm. Wait for the distress acknowledge
call from a coast station. If you do not receive the distress acknowledge call from a
coast station, which usually takes about five minutes from the time of receiving a dis-
tress alert, follow the flow charts on page 3-5.
If further DSC alerts are received from the same source and the ship in distress is be-
yond doubt in the vicinity, a DSC acknowledgment may, after consultation with a Res-
cue Coordination Center (RCC) or Coast Station, be sent to terminate the distress call.
Note 1: An asterisk (*) appearing in a distress alert message indicates an error at the
asterisk's location.
Note 2: Do not send the distress acknowledge call in response to receipt of distress
alert having the nature of distress as "EPIRB emission".
