WARNING: The attitude information provided by the GDL 51 is not intended
to be used as a source of attitude information for flight in instrument
meteorological conditions.

WARNING: This unit provides the ability to receive weather information
through external sources. Use weather data only as an aid to situational
awareness. Such weather information is merely supplemental and advisory
in nature and is not intended to be relied upon as safety-critical information
in connection with any aviation, vehicle, or marine usage. The user should
always exercise caution and common sense when confronted with severe
weather conditions.

WARNING: Do not use data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained within data
link weather products may not accurately depict current weather conditions.

WARNING: For safety reasons, GDL 51 operational procedures must be
learned on the ground.

WARNING: Use the GDL 51 only as an aid for VFR navigation. Do not
attempt to use the GDL 51 for any purpose requiring precise measurement
of direction, distance, location, or topography. This product should not be
used to determine ground proximity for aircraft navigation.

WARNING: The altitude calculated by the GPS receiver is geometric height
above Mean Sea Level and could vary significantly from the altitude displayed
by pressure altimeters.

WARNING: The pressure altitude information provided by the
GDL 51 in a pressurized airplane will not be accurate. Use the connected
display device to disable pressure information from the GDL 51.

WARNING: The GDL 51 has a very high degree of functional integrity.
However, the pilot must recognize that providing monitoring and/or self­test 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 GDL 51. 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 the cockpit.

WARNING: The GDL 51 contains a lithium-ion battery. To prevent damage,
remove the unit from the aircraft or vehicle when exiting or store it out of
direct sunlight.

WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
of all GPS equipment.

parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and the
