Memory Battery Low
—The internal lithium battery that maintains waypoint, route
and track plot memory (when the unit is off) needs to be replaced. Take your unit to
an authorized GARMIN service center for installation of a new battery.
No DGPS Position
—Not enough data is being received to compute a DGPS position
or unit has lost DGPS signal. Make sure the antenna coupler is properly grounded (see
Appendix A-Installation) and the correct frequency and bit rate are selected on the
Interface Setup page.
Off Course Alarm
—You have exceeded the off-course distance (left or right)
specified in the timer/alarm setup.
Oscillator Needs Adjustment
—The GPSMAP has detected excessive drift in its
internal oscillator which may result in longer acquisition times. Take your unit to an
authorized GARMIN service center for adjustment.
Poor GPS Coverage
—The GPSMAP cannot acquire the necessary number of satellites
to compute a position.
Power Down and Re-init
—The GPSMAP cannot calculate a position due to abnormal
satellite conditions. Power down and verify the last position shown by other means.
Proximity Alarm
—You have entered the alarm radius specified for the proximity
waypoint indicated.
Proximity Overlap
—The alarm radius specified overlaps the area specified for
another proximity waypoint. See section 9 for more information on proximity over-
laps.
RAM Failed
—The random access memory has failed and the unit is not operable.
Take your unit to an authorized GARMIN service center for repairs.
ROM Failed
—The permanent memory has failed and the unit is not operable. Take
your unit to an authorized GARMIN service center for repairs.
