CAUTION: The Global Positioning System is operated by the United States government, which is solely re-
sponsible 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 GNS 530 is a precision electronic NAVigation
AID (NAVAID), any NAVAID can be misused or misinterpreted and therefore become unsafe.
CAUTION: Use the GNS 530 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 GNS 530 to
all available navigation sources, including the information from other NAVAIDS, visual sightings, charts, etc.
For safety, always resolve any discrepancies before continuing navigation.
WARNING: The altitude calculated by the GNS 530 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.
WARNING: The Jeppesen database incorporated in the GNS 530 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 GNS 530 package. Pilots using an out-of-date database do so entirely at their own risk!
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.
CAUTION: The Garmin GNS 530 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.
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 harm-
ful interference to radio communications. Further-
more, there is no guarantee that interference 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 con-
necting 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 fol-
lowing conditions: (1) This device may not cause
harmful interference, and (2) this device must
accept any interference received, including interfer-
ence that may cause undesired operation.
