4. Calibration
4.1 Compass Calibration
Compass calibration is crucial for stable flight and accurate GPS functions. Perform this outdoors in an open area, away from magnetic interference.
- Place the drone on a horizontal surface and power it on.
- Power on the remote control. The drone will automatically match frequency.
- Short press the magnetic calibration button on the remote control. The drone's front arm lights will flash rapidly, and the rear arm lights will flash slowly.
- Pick up the drone and turn it horizontally until the remote control emits a beep.
- Then, turn the drone vertically until the remote control emits another beep.
- The front arm lights will turn solid, and the rear arm lights will flash slowly, indicating successful compass calibration.
4.2 Gyroscope Calibration
Gyroscope calibration ensures the drone's stability. Perform this on a flat, level surface.
- Place the drone on a horizontal surface.
- Press the gyroscope calibration button on the remote control. The drone's front and rear arm lights will flash alternately.
- Once the front arm lights turn solid and the rear arm lights flash slowly, the gyroscope calibration is successful.
