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 235 Sounder is a precision electronic NAVigation AID
(NAVAID), any NAVAID can be misused or misinterpreted and, therefore, become
unsafe.
Use the GPSMAP 235 Sounder 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 235 Sounder 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.
NOTE: The GPSMAP 235 Sounder generates, uses, and can radiate radio frequen-
cy energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. There is no guarantee that
interference will not occur in a particular installation. If the sounder does cause
harmful interference, the user is encouraged to try to correct the interference by relo-
cating 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.
The GPSMAP 235 Sounder complies with Part 15 of the FCC limits for class B
digital devices. Operation is subject to the following conditions: (1) The sounder
may not cause harmful interference, and (2) the sounder must accept any interfer-
ence received, including interference that may cause undesired operation.
