Receiving Distress Calls; Distress Sent By Another Vessel - M-tech MT-500 Owner's Handbook Manual

• Establish voice contact with the coast station on Channel 16.

7.3 Receiving Distress Calls

Your MT-500 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-500 does not automati-
cally reply to, or relay, distress or ACK or relay DSC calls.

Distress sent by another vessel

If your MT-500 transceiver intercepts a distress call from another vessel, an
alarm sounds and the following screen appears in the display.
Name or ID of
Vessel in Distress
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.
