Step 1:Horizontal calibration
When the APP prompts you to rotate the aircraft horizontally,put the aircraft in your hand horizontally and then rotate it horizontally
until the status indicator light on the arm of the aircraft turns red and green light flashing alternately (i.e., the horizontal calibration is
successful).
Step 2:Vertical calibration
When APP prompts you to rotate the aircraft with its nose
facing up, hold the aircraft in your hand with its nose facing up.
Place the aircraft on the ground and then rotate it horizontally.
The compass has been calibrated successfully when the status
indicator light on the aircraft's rear arm turns green (solid or
flashing).
When the APP prompts you with "calibration is successful",
click "Complete" to complete calibration.
If the status indicator light turns red (about 6 seconds),which
means compass calibration fails, please change the position
and re-calibrate.
