Do not calibrate your compass near large metal objects or in places with strong
magnetic field interferences.
The process of compass calibration is as follows:
1. Expand the Arms. Turn on the aircraft. Connect to the aircraft's Wi-Fi. Enter Do.Fun's "Settings" -
"Compass Calibration", and tap on "Start".
2. Keep the aircraft horizontal (the Aircraft Status Indicator will turn solid green if
it's set to the required angle). Slowly rotate it 2-3 times. During this rotation,
make sure the indicator stays solid green, or you will need to adjust the
aircraft's angle once again. The app will automatically jump to the next step
once it's done.
3. Keep the aircraft head vertical downwards (the Aircraft Status Indicator will
turn solid white if it's set to the required angle). Slowly rotate it 2-3 times.
During this rotation, make sure the indicator stays solid white, or you will
need to adjust the aircraft's angle once again.
4. The app will notify you once calibration is completed. At this point the Aircraft Status Indicator will show
the aircraft's actual status.
After the horizontal calibration, immediately begin the vertical calibration, don't stop

midway.
