3.9 G3X Touch Failure Annunciations
If a G3X Touch
function fails, a large red ‘X’ is typically displayed over the instrument(s) or data
experiencing the failure. Upon G3X Touch power-up, certain instruments remain invalid as
equipment begins to initialize. All instruments should be operational within one minute of power-up.
If any instrument remains flagged the G3X Touch should be serviced by a Garmin-authorized repair
facility.
