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 G500 utilize
GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as
with all NAVAIDs, information presented by the G500 can be misused or
misinterpreted and, therefore, become unsafe.
CAUTION: The Garmin G500 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 G500 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 G500 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: Terrain data is not displayed when the aircraft latitude is greater
than 75° North or 60° South.
