7.3 Receiving Distress Calls
Your
MT-550
transceiver may intercept distress messages sent by another vessel
and/or acknowledgments (ACK) sent by a coast station to another vessel in distress.
In such cases you should maintain a listening watch on channel 16 and standby to
lend assistance. Your
MT-550
does not automatically reply to, or relay, distress or
ACK or relay DSC calls.
Distress sent by another vessel
If your
MT-550
transceiver intercepts a distress call from another vessel, an alarm
sounds and the screen presents time of distress, MMSID of the distressed vessel,
and Lat/Lon coordinates. The plus sign (+) indicates there is another page of
information available. If invalid GPS or Time data is received, the Lat/Lon position
shows “9” in all digits and the time shows all “8”s.
