APPENDIX
Messages
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 cartridge inserted is not readable by the
GPSMAP system and may be damaged or the card may have been inserted too quickly
to be read. Slowly 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.
Crosstrack 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.
Degraded Accuracy—The accuracy of your GPSMAP system has been degraded
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 installation of a new battery.
Need Altitude—Your GPSMAP 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 175 needs to be initialized to your present
position. See pages 6-8 for complete instructions on initialization.
No Differential GPS Position—Not enough data is being received to compute a
DGPS position.
Oscillator Needs Adjustment—The GPSMAP 175 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 175 cannot acquire the necessary number of
satellites to compute a position.
Power Down and Re-init—The GPSMAP 175 cannot calculate a position due to
abnormal satellite conditions. Power down and verify the last position shown by other
means.
