Begin search and rescue operation for the vessel in distress.
Procedure when in area A1
1. When the FM-8800D/S receives a distress alert from another vessel, the
ALARM LED (red) blinks and the FM-8800D/S sounds the distress alarm.
2. Silence the alarm by pressing the CANCEL key.
3. Wait up to five minutes until the DIST ACK signal from a coast station is
received. Be prepared to follow the instructions of the coast station.
4. If you do not receive the DIST ACK signal, follow the flow chart shown on
page 2-9 to determine if your vessel should acknowledge a distress alert.
If further DSC alerts are received from the same source and the ship in distress
is beyond doubt in the vicinity, a DSC acknowledgement may, after consultation
with a Rescue Co-ordination Center (RCC) or Coast Station, be sent to
terminate the distress call.
Note 1: An asterisk (*) in a received distress alert message indicates error or
unknown at the location marked with the asterisk. For POS field,
“-“ appears when a position data has no fractional part.
Note 2: Do not send DIST ACK in response to receipt of distress alert having the
nature of distress as “EPIRB emission”.
