INTRODUCTION
Cautions
NOTE: This device complies with Part 15 of the
FCC limits for Class B digital devices. This equip-
ment generates, uses, and can radiate radio fre-
quency energy and, if not installed and used in
accordance with the instructions, may cause harm-
ful 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 connect-
ing 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 follow-
ing conditions: (1) This device may not cause harm-
ful interference, and (2) this device must accept
any interference received, including interference
that may cause undesired operation.
The GARMIN GNS 430 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 Part 15 regulations.

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 GNS 430 is a precision electronic NAVigation AID
(NAVAID), any NAVAID can be misused or misinterpreted and therefore become
unsafe.
Use the GNS 430 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 430 to all avail-
able navigation sources, including the information from other NAVAIDS, visual
sightings, charts, etc. For safety, always resolve any discrepancies before continuing
navigation.
The altitude calculated by the GNS 430 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.
The Jeppesen database incorporated in the GNS 430 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 430 package.
Pilots using an out-of-date database do so entirely at their own risk.

CONVENTIONS USED IN THIS MANUAL
A circled number (e.g.,””) will appear next
to many of the illustrations shown along the
side of a page. This number refers back to a
specific step on the same page (or in rare
instances, to a step on the following page).
When more than one option is possible within
a procedure, the procedures are described
using an “a”/”b” convention with the same
numbering (e.g., “3a” and “3b” for two step#3
options). This same convention is used when
multiple procedures are listed on the same
page and illustrations are provided for the
steps described in one or both procedures
(e.g.,”a” and ”b”).
A highlighted “NOTE” area appears on many
pages to point out additional information or
items of particular importance related to a
given subject.
