Cautions - Garmin GPS 500 Pilot's Manual & Reference

Introduction

Cautions

NOTE: This device complies with Part 15 of the
FCC limits for Class B digital devices. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause
harmful interference to radio communications.
Furthermore, there is no guarantee that interfer-
ence will not occur in a particular installation.
If this equipment does cause harmful interfer-
ence, the user is encouraged to try to correct the
interference by relocating the equipment or
connecting the equipment to a different circuit than
the affected equipment. Consult an authorized dealer
or other qualified avionics technician for additional
help if these remedies do not correct the problem.
Operation of this device is subject to the
following 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.

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 GPS 500 is a precision electronic
NAVigation AID (NAVAID), any NAVAID can be misused or misinterpreted and therefore become unsafe.
I
CAUTION: Use the GPS 500 at your own risk. To reduce the risk of unsafe operation, carefully review and
understand all aspects of this 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
GPS 500 to all available navigation sources, including the information from other NAVAIDS, visual
sightings, charts, etc. For safety, always resolve any discrepancies before continuing navigation.
I
WARNING: The altitude calculated by the GPS 500 is geometric height above mean sea level and could
vary significantly from altitude displayed by pressure altimeters in aircraft. GPS accuracy may be degraded
by the U.S. Department of Defense-imposed Selective Availability (SA) program. With "SA" on, GPS
altitude may be in error by several hundred feet. Never use GPS altitude for vertical navigation.
I
WARNING: The Jeppesen database incorporated in the GPS 500 must be updated regularly in order to
ensure that its information is current. Updates are released every 28 days. A database information packet is
included in your GPS 500 package. Pilots using an out-of-date database do so entirely at their own risk!
I
CAUTION: GPS receivers operate by receiving and decoding very low power radio signals broadcast by
satellites. It is possible that in some situations other radio equipment or electronic equipment used in close
proximity to a GPS receiver may create electromagnetic interference (EMI) which may affect the ability of the
GPS receiver to receive and decode the satellite signals. In such event, the interference may be reduced or
eliminated by switching off the source of interference or moving the GPS receiver away from it.
I
CAUTION: The Garmin GPS 500 does not contain any user-serviceable parts. Repairs should only be
made by an authorized Garmin service center. Unauthorized repairs or modifications could void your
warranty and authority to operate this device under FCC Part 15 regulations.
