the GDU 620. With a GSU 75/GRS 79/GDC 72 installation, exceeding 225
deg/second in pitch or roll may invalidate AHRS attitude provided to the
GDU 620. Exceeding 435 KIAS may invalidate ADC information provided

WARNING: Because of anomalies in the earth's magnetic field, operating
the G500/G600 within the following areas could result in loss of reliable
attitude and heading indications. North of 72° North latitude and south
of 70° South Latitude. An area north of 65° North latitude and between

WARNING: Do not use Terrain-SVT information for primary terrain
avoidance. Terrain-SVT is intended only to enhance situational awareness.
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 G500/G600 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
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.
