1. Press the C1 button and C2 button once, then press and hold them until the remote controller beeps. When the remote controller emits “DDD, DDD, …” sounds, the calibration is enabled successfully.
Note: Do not touch the joystick before the calibration is enabled, or the calibration will fail to be enabled. If so, operate the preceding operations again.
2. Push the joystick to the endpoints in multiple directions (top, bottom, left, and right) multiple times and rotate the roll axis knob clockwise and counterclockwise to the end point, respectively.
3. Press and hold the C1 and C2 buttons at the same time to complete the calibration. When the remote controller emits “DD” sounds, the calibration is complete. If no sound is heard, the calibration fails. If so, operate the preceding steps to recalibrate the joystick.
