Compass has to be calibrated before using the first time. If else, it cannot work and will
affect flying safety. Calibration tips:
Please do not calibrate it in the place close to the high-magnetic field or big metal
materials, such as high-voltage, magnet, parking lot, concrete iron building, etc.
When calibrating, please do not bring the magnetic materials, such keys and
cellphone.
If it is calibrated indoor, please do not re-calibrate it outdoor. It prevents that the two
magnet differences cause the potential flying data errors.
Magnetic field location is different, please make sure re-calibrate when it changes to
the place far away from the previous one.
