However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to other equipment, which can be
determined by turning the equipment off and on, the user is
encouraged to try and correct the interference by relocating
the equipment or connecting the equipment to a different cir-
cuit than the affected equipment. Consult an authorized

CAUTION
The GPS 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 155 is a precision electronic NAVigation AID (NAVAID), any NAVAID
can be misused or misinterpreted, and therefore become unsafe.
Use the GPS 155 at your own risk. To reduce the risk of unsafe operation, careful-
ly review and understand all aspects of this Owner’s Manual and Flight Manual
Supplement, and thoroughly practice using the simulator mode prior to actual use.
When in actual use, carefully compare indications from the GPS 155 to all available
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 GPS 155 is geometric height above mean sea level
and could vary significantly from altitude displayed by pressure altimeters in aircraft.
NEVER use GPS altitude for vertical navigation.
The Jeppesen database incorporated in the GPS 155 must be updated regularly in
order to ensure that its information is current. Updates are released every 28 days.
Contact Jeppesen for more information on GPS 155 database updates.
Pilots using an out-of-date database do so entirely at their own risk.
CAUTION! The GARMIN GPS 155 has no user serviceable parts. Should you ever
encounter a problem with the unit, please take it to an authorized GARMIN dealer
for repairs.
