Active WPT Can’t be Deleted—
You have attempted to change the “active to” or “active from”
waypoint. Clear the active route or GOTO before making your changes.
Accuracy has been Degraded—
The accuracy of the GPS 48 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.
Already Exists—
The name you are entering already exists in the GPS 48’s memory.
Approaching—
You are one minute away from reaching a destination waypoint.
Battery Power is Low—
The batteries are low and should be replaced.
No DGPS Position—
Not enough data is available to compute a DGPS position.
No RTCM Input—
Beacon receiver is improperly connected or baud rates do not match.
Poor GPS Coverage—
The GPS 48 cannot acquire the necessary number of satellites to com-
pute a position. Try another location with a clearer view of the sky.
Power Down and Re-init—
The GPS 48 is not able to calculate a position due to abnormal
satellite conditions. Turn the unit off and verify the last position shown by other means. Try the
unit again later, possibly in a different location.
PROX Alarm—
You have entered the alarm circle for a specific proximity waypoint.
Proximity Overlapped—
The alarm circles of two proximity waypoints overlap which could
cause difficulty in monitoring distances to each waypoint.

The waypoint you are trying to delete is listed as a proximi-
ty waypoint and must be removed from the list before it can be deleted.
Read Only Mem has Failed—
The permanent memory has failed and the unit is not operable.
