[TG] [TG11] MFD Lockup-alarm active

[BernieK]

Well we had another fishing day.

The same fault happened again. At the end of the route, the p70r said end of route and I acknowledged on the P70r.
But I had an alarm on the MFD beeping away and I could not stop it or acknowledge it. I SUSPECT it might be a pilot alarm (route complete?). I often get a pilot lost alarm if I power down the p70r which is annoying since the MFD is set NOT to control the pilot. Usually this has a banner though and I just need to press OK

I had 3 apps running on the screen, navigation (1/4 screen), fishfinder (1/4 screen) and dashboard (1/2 screen).

All apps continued working, though I could not alter anything as all controls as I was unable to use any controls. It was not convenient at the time to cycle the power and as we were close to port I just put up with it.
BUT I got a AIS danger warning alarm and I was able to clear it by turning off my Ray73. This also cleared the background alarm. I then got an AIS data lost alarm which I was able to clear as normal.

The phantom alarm does not appear in the alarm log.
