When an LRU or an LRU function fails, a large red

NOTE: Upon power-up of the G1000 system,
certain windows remain invalid as G1000
equipment begins to initialize. All windows
should be operational within one minute of
power-up. Should any window continue to
remain flagged, the G1000 system should be
serviced by a Garmin-authorized repair facility.
