The projector contains a cooling fan, which may produce some noise during operation. This is normal and is similar to other electronic devices like computers. We have measured the projector's noise level to be around 35 dB, which is the average calculated from measurements taken in various directions (up and down, left and right, front and back) at a distance of one meter.

If you are experiencing unusually loud fan noise, consider the following:
1. Gently shake the machine to confirm that if any parts have fallen out from the inside
2. Please send us a short video demonstrating the problem? You can upload the video to a file-sharing service like WeTransfer or a similar platform. Once uploaded, kindly send us a screenshot or PDF containing the download link using the "Attach File(s)" feature in the Message Center.

1. Remove Protective Film or Clean the Lens: Peel off any protective film from the lens, or gently clean the lens with a soft cloth.
