Alarm Clock—The alarm clock has sounded.
Anchor Drag Alarm—You have drifted out of
the specified distance range.
Approaching—You are less than one minute
away from reaching a destination waypoint at
your present speed over ground.
Arrival At—You have arrived at the destination
waypoint.
Can’t Change An Active Waypoint—You have
attempted to change the ‘active to’ or ‘active from’
waypoint. Clear the active route or GOTO before
making your changes.
Card Format is Not Recognized—The car-
tridge inserted is not readable by the GPSMAP
235 Sounder system and may be damaged.
Reinsert the cartridge to make sure it is properly
installed. If the cartridge is still not recognized,
call the G-chart information line at 1-800-427-
6460.
Cross-Track Alarm—You have exceeded the
off-course distance specified in the CDI setup.
Data Transfer is Complete—The receiver is fin-
ished uploading or downloading information to
the connected device.
Database Memory has Failed—The built-in 64
nm (32 in U.S.) database has failed. See an autho-
rized service center for repair.
Deep Water Alarm—The current depth is equal
to or more than the set alarm depth.
Degraded Accuracy—The accuracy of your
GPSMAP 235 Sounder system has been degraded
beyond 500 meters due to poor satellite geometry
or data quality.
Max Calibration Is 5000mt (16,400 ft)—You
have exceeded the maximum possible map cali-
bration.
Memory Battery Power is Low—The internal
battery that stores waypoints, routes and track
plots needs to be replaced. Take your unit to an
authorized GARMIN service center for installation
of a new battery.
Need Altitude—Your GPSMAP 235 Sounder sys-
tem needs the altitude to maintain a position fix
due to poor satellite coverage. Enter your approx-
imate altitude on the initialize Position Page.
Need to Select Init Method—The GPSMAP 235
Sounder needs to be initialized to your present
position. See pages 1-2 for complete instructions
on initialization.
No Differential GPS Position—Not enough
data is being received to compute a DGPS posi-
tion.
No Transducer, Sounder Turned Off—The
unit has detected that its transducer has been
removed and has shut the sounder off. GPS is still
functional.
Oscillator Needs Adjustment—The GPSMAP
235 Sounder has detected excessive drift in its
internal oscillator, which may result in longer
acquisition times. Take the unit to an authorized
GARMIN service center for adjustment.
Poor GPS Coverage—The GPSMAP 235
Sounder cannot acquire the necessary number of
satellites to compute a position.
Power Down and Re-init—The GPSMAP 235
Sounder cannot calculate a position due to abnor-
mal satellite conditions. Power down and verify
the last position shown by other means.
