Receiving a Distress ACK Sent from a Coast Station
When a Distress ACK is received from a Coast Station (Coast Guard or
Search and Rescue) the Distress alarm sounds. The LCD displays the Name/
MMSI ID of the vessel in distress. Maintain radio silence and a listening
watch on channel 16 and standby to lend assistance if requested.
Receiving a Distress Relay Sent by Another Station
When a Distress Relay is received from another station, an alarm sounds and
the LCD displays two alternating screens. The first page displays the Name/
MMSI ID of the station sending the message. The second page displays the
Name/MMSI ID of the vessel in distress and its lat/lon position. Your radio
does not re-send a distress relay message.
Maintain radio silence and a listening watch on channel 16 and standby to
lend assistance if requested.
