INTRODUCTION
Warning and Caution
WARNING!
The electronic chart is an aid to navigation and is designed to facilitate the use of
authorized government charts, not replace them. Only official government charts and
notices to mariners contain all information needed for the safety of navigation–and,
as always, the user is responsible for their prudent use.
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 GPSMAP 175 is a precision electronic NAVigation AID (NAVAID),
any NAVAID can be misused or misinterpreted and, therefore, become unsafe.
Use the GPSMAP 175 at your own risk. To reduce the risk of unsafe operation,
carefully review and understand all aspects of this Owner’s Manual—and
thoroughly practice operation using the simulator mode prior to actual use. When
in actual use, carefully compare indications from the GPSMAP 175 to all available
navigation sources, including the information from other NAVAIDs, visual
sightings, charts, etc. For safety, always resolve any discrepancies before
continuing navigation.
NOTE: 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. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does
cause harmful interference, the user is encouraged to try to correct the interference
by relocating the equipment or connecting the equipment to a different circuit.
Consult an authorized dealer or other qualified technician for additional help if
these remedies do not correct the problem.
This device complies with part 15 of the FCC limits for class B digital devices.
Operation 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.
The GPSMAP 175 contains no user-serviceable parts. Repairs should only be
made by an authorized service center. Unauthorized repairs or modifications
could void your warranty and your authority to operate this device under Part 15
regulations.
