APPENDIX C
The GPS 12 uses a flashing on-screen message indica-
tor to alert you to important information. Whenever the
message indicator appears, press PAGE to view the mes-
sage page. There are two types of messages: temporary
alerts and condition alerts. Temporary alerts are cleared
from the message page after viewing, while condition
alerts remain until the condition has been resolved. Pay
careful attention to all messages for your own safety.
Active WPT Can’t be Deletd—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 12 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.

or at the distance specified on the alarms submenu.

CDI Alarm—You are left or right of course, beyond the limits set on the alarms submenu.
No DGPSPosition—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 GPSCoverage—The GPS 12 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 12 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.
Proximity Wpt can’t be Deleted—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.
Received an Invalid WPT—A waypoint was received during upload transfer that has an
invalid identifier.
Receiver has Failed—A failure in receiver hardware has been detected. If this message persists,
