PREFACE
GARMIN thanks you for selecting our high performance, full featured
Personal NavigatorTM. The GPS 75 represents our continued commitment
to provide you with a portable navigation unit that is versatile, extremely
accurate, and easy to use. We are confident you will enjoy using your unit
for many years to come.
The GPS 75's rugged construction and quality components offer the
reliability demanded by the harshest operating environments. It may be
used in marine and land vehicles, as well as by hunters, hikers, and
military forces. The unit may be operated portably using its own battery
pack, or it may use a 5-40 volt DC external power source for fixed
mounted applications. You can even use a 115- or 230-volt battery
charger for planning trips at home.
This manual and accompanying quick reference guide provide complete
information on safely operating the GPS 75 to its full potential. A
practice voyage has been planned for you to practice your navigation
skills using the built-in simulator. Afterwards, try a trip of your own to
realize the value of the GPS 75 as your Personal NavigatorTM. If you have
any questions or comments, our Product Support Department is eager to
serve you. GARMIN is fully committed to your satisfaction as a
customer.

system is under development and is subject to changes which could affect
the accuracy and performance of all GPS equipment. Although the GPS
75 is a precision electronic NAVigation AID (NAVAID), any NAVAID can
be misused or misinterpreted, and therefore become unsafe. Use the
GPS 75 at your own risk. To reduce the risk, 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 GPS 75 to all available
navigation sources including the information from other NAVAIDs,
visual sightings, charts, etc. For safety, always resolve any discrepancies
before continuing navigation.
