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
135 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
finished uploading or downloading information
to the connected device.
Database Memory has Failed—The built-in
64 nm database has failed. See an authorized
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 135 Sounder system has been degrad-
ed beyond 500 meters due to poor satellite
geometry or data quality. You should check
other navigational sources to verify the position
indicated.
Max Calibration Is 5000mt (16,400 ft)—
You have exceeded the maximum possible map
calibration.
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 installa-
tion of a new battery.
Need Altitude—Your GPSMAP 135 Sounder
system needs the altitude to maintain a position
fix due to poor satellite coverage. Enter your
approximate altitude on the initialize position
page.
Need to Select Init Method—The GPSMAP
135 Sounder needs to be initialized to your pre-
sent 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.
Oscillator Needs Adjustment—The GPSMAP
135 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 135
Sounder cannot acquire the necessary number
of satellites to compute a position.
Power Down and Re-init—The GPSMAP 135
Sounder cannot calculate a position due to
abnormal satellite conditions. Power down and
verify the last position shown by other means.
