The compass is factory calibrated making user-calibration unnecessary. If you experience compass error warnings, or the aircraft’s flight direction does not match control inputs you may need to calibrate the compass using the following procedure.
The compass is very sensitive to electromagnetic interference causing compass error and poor flight. If you find the compass abnormal after calibration, move the aircraft to another location and try again.
Remember to meet the following requirements when carrying out compass calibration:
1. Operate calibration outdoors (ideally on an open area such as a lawn).
2. Be free from all magnetic interference, such as magnetite or steel reinforcement found in concrete. Building and other structures may also result in a poor calibration.
3. Stay away from both underground and overhead power lines.
4. Do not carry ferromagnetic materials (e.g., keys, magnetic jewelry, etc.) with you.
5. Remove electronic devices that might interfere with the calibration (e.g., cell phones, remote controller, etc.)
1. Start the calibration process by pressing the Take-off/Landing Button () and Go Home Button () on the remote controller simultaneously for 3 seconds. When the calibration process has been initiated, the rear flight LEDs on the aircraft will turn solid yellow.
2. Hold the aircraft horizontally and rotate it until the rear flight LEDs on the aircraft turn solid green, indicating this step has been completed successfully.
3. Hold the aircraft vertically with the nose facing downward and rotate it until the rear flight LEDs on the aircraft flash slow green, indicating that your calibration is successful.
• If the calibration is unsuccessful, the rear flight LEDs on the aircraft will illuminate flashing red. In this case, repeat the above steps to try again.
• You can also calibrate the compass using the Autel Explorer™ app, the instruction is available in the App Manual.
