and such interference will result in abnormal data affecting the flight, and even lead to
flight accidents.
Do not calibrate it in areas with strong magnetic field, such as magnetic deposits,
parking lots, construction areas with underground bars.
！
Note: Do not carry with ferromagnetic material, such as keys, mobile phones, etc.
when calibrating.
1.Do not calibrate near bulks of metals.
2.Do not calibrate the magnetic compass indoors.
Calibration method for Magnetic compass:
1. You need to start the aircraft (the aircraft is horizontally placed) and the remote,
immediately toggle the indicator lights of aircraft when finished self-checking, switching
two gears with SA button(5 to 10 times back and forth): the red, blue and green
indicator lights flash alternatively, and enter the calibration mode. After the indicator
turns to blue and glows for 3 seconds, you can rotate as shown by picture, and you can
turn to the next side for rotating after the green indicator flashes for one time (as shown
by Figure below);
Horizontal calibration vertical calibration (head down)
2. After two sides are successfully calibrated, the green indicator will flash
consecutively, and if the calibration fails, the red indicator will flash consecutively,
indicating that you need to calibrate it once again.
Note you need to perform calibration once again less than one of following
circumstance:
1.The aircraft hasn't filed for a long time.
2.The flight site is far from the site of the last magnetic compass calibration.
3.During flight, the circling or shift is quite serious or you cannot fly in a straight line.
