WARNINGS,
CAUTIONS, & NOTES
CAUTION: The Global Positioning System is operated by the United States government, which is solely
responsible for its accuracy and maintenance. The system is subject to changes which could affect the accuracy
and performance of all GPS equipment. Although the Garmin 400/500 Series units are precision electronic
NAVigation AIDS (NAVAID), any NAVAID can be misused or misinterpreted and therefore become unsafe.
CAUTION: Use the 400/500 Series units at your own risk. To reduce the risk of unsafe operation, carefully
review and understand all aspects of the Owner's Manual and the Flight Manual Supplement, and thoroughly
practice basic operation prior to actual use. When in actual use, carefully compare indications from the unit
with all available navigation sources, including the information from other NAVAIDS, visual sightings, charts,
etc. For safety, always resolve any discrepancies before continuing navigation.

compare indications from the Garmin Series Unit with all available navigation sources, including the information
from other NAVAIDS, visual sightings, charts, etc. For safety, always resolve any discrepancies before continuing
navigation.The altitude calculated by the Garmin 400 Series Unit is the geometric height above mean sea level
and could vary significantly from the altitude displayed by pressure altimeters in the aircraft.
CAUTION: The Jeppesen database incorporated in the Garmin 400/500 Series units must be updated regularly
in order to ensure that its information is current. Updates are released every 28 days. A database information
