There is noise on the Mi Smart Projector.

Troubleshooting if there is noise on the Mi Smart Projector, please refer to the following steps:
1. Check the projector's fan and ensure it's clean and free from obstructions. Dust or debris can cause noise during operation;
2. Verify that the projector is placed on a stable surface. Vibrations from unstable surfaces can amplify noise;
3. Ensure that the projector's ventilation is not blocked. Adequate airflow is essential to prevent overheating, which can lead to increased fan noise;
4. If the noise persists, try adjusting the projector's settings, such as fan speed or power mode, to see if it reduces the noise;
5. If you're using external speakers, check their connections and placement. Interference or feedback from external audio devices can cause noise;
6. Consider updating your projector's firmware to the latest version. Firmware updates may include fixes for noise-related issues;
7. If none of the above steps resolve the noise issue, contact your local after-sales for further assistance regarding this issue.
