WARNING: Navigation and terrain separation must NOT be predicated
upon the use of the terrain function.The GDU 620Terrain Proximity feature
is NOT intended to be used as a primary reference for terrain avoidance
and does not relieve the pilot from the responsibility of being aware of
surroundings during flight.The Terrain Proximity feature is only to be used
as an aid for terrain avoidance and is not certified for use in applications
requiring a certified terrain awareness system. Terrain data is obtained
from third party sources. Garmin is not able to independently verify the
accuracy of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory
in nature and should not be relied upon as the sole source of obstacle and
terrain avoidance information.Always refer to current aeronautical charts
for appropriate minimum clearance altitudes.
WARNING: The Garmin GDU 620 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 GDU 620. 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 altitude calculated by GPS receivers is geometric height
above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters, such as the output from the GDC 74A Air
Data Computer, or other altimeters in aircraft. GPS altitude should never
be used for vertical navigation. Always use pressure altitude displayed by
the GDU 620 PFD or other pressure altimeters in aircraft.
WARNING: Do not use outdated database information. Databases used
in the G600 system must be updated regularly in order to ensure that the
information remains current. Pilots using an outdated database do so
entirely at their own risk.
WARNING: Do not use basemap (land and water data) information for
primary navigation. Basemap data is intended only to supplement other
approved navigation data sources and should be considered as an aid to
enhance situational awareness.

WARNING: Traffic information shown on the GDU 620 Multi Function
Display is provided as an aid in visually acquiring traffic. Pilots must
maneuver the aircraft based only upon ATC guidance or positive visual
acquisition of conflicting traffic.
WARNING: XM Weather should not be used for hazardous weather
penetration.Weather information provided by the GDL 69/69A is approved
only for weather avoidance, not penetration.
WARNING: NEXRAD weather data is to be used for long-range planning
purposes only. Due to inherent delays in data transmission and the relative
age of the data, NEXRAD weather data should not be used for short-range
weather avoidance.
WARNING: For safety reasons, GDU 620 operational procedures must be
learned on the ground.
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the G600 Pilot’s Guide. Thoroughly practice
basic operation prior to actual use. During flight operations, carefully
compare indications from the GDU 620 to all available navigation sources,
including the information from other NAVAIDs, visual sightings, charts, etc.
For safety purposes, always resolve any discrepancies before continuing
navigation.
WARNING: Never use the GDU 620 to attempt to penetrate a thunderstorm.
Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airman’s
Information Manual (AIM) recommend avoiding “by at least 20 miles any
thunderstorm identified as severe or giving an intense radar echo”.
CAUTION: 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. Portions of the Garmin GDU 620 utilize
GPS as a precision electronic NAVigation AID (NAVAID).Therefore, as with
all NAVAIDs, information presented by the GDU 620 can be misused or
misinterpreted and, therefore, become unsafe.

CAUTION: The Garmin GDU 620 does not contain any user-serviceable
parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and
the pilot’s authority to operate this device under FAA/FCC regulations.
CAUTION: The GDU 620 PFD and MFD displays use a lens coated with a
special anti-reflective coating that is very sensitive to skin oils, waxes, and
abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE
ANTI-REFLECTIVE COATING. It is very important to clean the lens using a
clean, lint-free cloth and an eyeglass lens cleaner that is specified as safe
for anti-reflective coatings.
NOTE: Interference from GPS repeaters operating inside nearby hangars
can cause an intermittent loss of attitude and heading displays while the
aircraft is on the ground. Moving the aircraft more than 100 feet away
from the source of the interference should alleviate the condition.
NOTE: All visual depictions contained within this document, including
screen images of the GDU 620 bezel and displays, are subject to change
and may not reflect the most current GDU 620 system. Depictions of
equipment may differ slightly from the actual equipment.
NOTE: This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
NOTE: This product, its packaging, and its components contain chemicals
known to the State of California to cause cancer, birth defects, or
reproductive harm. This notice is being provided in accordance with
California’s Proposition 65. If you have any questions or would like
additional information, please refer to our web site at www.garmin.com/
