Precautions
The compass must sometimes be calibrated before ight. As the compass is susceptible to the
complex environment outside, when calibrating the compass, attention should be paid to the
following matters in order to ensure the accuracy of the compass. This is to ensure an ideal condi-
tion of the aircraft.
1.The calibration site should be open, and away from strong magnetic elds, such as magnetic
mines, parking lots, or construction areas with underground steel.
2.Do not carry magnetic items, such as mobile phones and keys.
3.Do not calibrate the compass indoors.
Compass calibration procedures
1.Open Vision + App. After ensuring the device is connected, enter the “Start to y” interface, and
then click “Setup” in the lower right corner of the menu bar. Then select “Flight Attitude and
Compass Calibration” in the ight setup list. Click “Calibration” to enter the “Compass Calibration”
interface, and the compass calibration program starts.
2.There are six setting positions in the interface, as shown in the gure. Calibration sequence of
the three positions is not limited. First, keep it in one position. When the image of the correspond-
ing position of the aircraft becomes yellow, it indicates that the direction has been identied.
Then rotate the aircraft around the vertical axis of the current position. When the color of the
image turns green, it indicates that the calibration of this direction is completed. Then calibrate
the other positions in the same way:
