Troubleshooting
When flying a pattern, you may encounter a Lightbar warning.
Warnings may include spraying a previously sprayed swath
(double-spray warning) or invalid or poor DGPS reception.
The Lightbar will flash a warning in this case. Your active guidance
will disappear from the Lightbar; you will see flashing LEDs and/or
additional error information in the left and right display screen in
its place.

swath the display will blink and you will see an
underscore in front of the swath number.

extrapolated GPS signal from last signal. Reboot

LED displays will show GPS - 00 if you lose the GPS
