Question, I just installed a used FA50 into a NN3 network.
I was able to login though the NN3 system menu to the FA50 using the keypad selector displayed by FA50 through the NN3 screen.
The MMSI field was all zeros, the boatname and call sign were blank.
I was then able to enter by boat name in the boatname but am unable to enter an MMSI number into the MMSI field. If I try and erase the zeros with the back arrow key, I exit out of the FA50 screen back to NN3, if I try and type any number or letter into the MMSI fiel nothing happens.
Is there an additional secret needed to get an MMSI in there?
