That number 972696005 decodes as follows:
Man overboard DSC and/or AIS devices (972yyzzzz)
yy = 69 = (presumably Icarus Aviation Limited)
ZZZZ = 6006 = sequence number chosen by the manufacturer, in your case the numbers appended to your S/N.
It is a number that functions under the MMSI system, but is not actually an MMSI as they were originally intended to be used, because there are too many.
My MMSI for my Gen 1 is 338131687, which decodes to:
338 = US (intended to be for a ship)
131687 = no meaning other than this is me
So you have a unique identifier that allows you to be searched for and hopefully found!
I don't know why Nautilus calls your number a NMS, but it probably means something like Nautilus Maritime Service.
Thanks. That clear things a bit.
Where does it say NMS? My iPhone may not take a good picture, but the letter before 972696005 is MMSI, not NMS.
