Your antenna seems to be mis alighned. Its ZERO point must be readjusted.
I think proton instructions will work just fine for you.
Good luck and happy Boating

the heading on top of display seems to be accurate. no heading sensor alarm
The problem is solved. Somehow my antenna "type" was changed in the menu! We don't know how this happened. everything works ok now.
