WARNING: The Garmin GTN 725/750 has a very high degree of functional
integrity. However, the pilot must recognize that providing monitoring
and/or self-test capability for all conceivable system failures is not

practical. Although unlikely, it may be possible for erroneous operation
to occur without a fault indication shown by the GTN 725/750. It is thus

the responsibility of the pilot to detect such an occurrence by means of
cross-checking with all redundant or correlated information available in
