One last issue remains on the installation we did 3 years ago (!) which we cannot resolve. Any help would be so gratefully accepted....
Furuno kit installed includes: 2117 BB Radar; NN3D; SC50.
Every so often, the NN3D gives a single audible alarm. Nothing happens on any kit at all, and the only indication of what it might have been is in the Alarm Log which records HEADING MISSING every time it happens.
We cannot trace why this happens. Any ideas? Thank you.
