 You’re required to calibrate your compass in the following cases!
 Before the first flight, and before the first outdoor flight;
 The location you are flying is quite far from the last location you flew;
 The Aircraft Status Indicator is fast purple flashing, indicating compass failure;
 The Aircraft drifts severely, for example: cannot fly straight.
 Expand the arms before calibrating, so as to avoid interference.
 Do not calibrate your compass near large metal objects or in places with strong
magnetic field interferences.
 Do not place DOBBY close to other magnetic materials and electronic devices (such as
magnet, mobile phone, tablet PC and stereo equipment).
The process of compass calibration is as follows:
1. Unfold the Arms, then 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.
 The calibration will take effective immediately (no need to restart the aircraft).
