Garmin GPS 40 - Manual (Page 55)

The GPS 40 uses a flashing on-screen message indicator to alert you to important
information. Whenever the message indicator appears, press the P key to view the
message 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 on the message page until the condition has been resolved. Pay careful attention
to all messages for your own safety.
Accuracy has been Degraded—The accuracy of the GPS 40 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 waypoint name you are entering already exists in the GPS 40’s
memory.
Approaching—You are less than one minute away from reaching a destination waypoint.
Battery Power is Low—The batteries are low and should be replaced.
Can’t change Active WPT—You have attempted to change the ‘active to’ or ‘active from’
waypoint. Clear the active route or GOTO before making your changes.
No DGPS Position—Not enough data is being received to compute a DGPS position.
No RTCM Input—Beacon receiver is not properly connected or baud rates do not match.
Poor GPS Coverage—The GPS 40 cannot acquire the necessary number of satellites to
compute a position. Try moving to a location with a clearer view of the sky.
Power Down and Re-init—The GPS 40 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.
Read Only Mem has Failed—The permanent memory has failed and the unit is not
operable. Take your unit to an authorized GARMIN dealer for repairs.
