1. To ensure the longevity of your projector, it is important to avoid placing it in excessively
hot or cold environments. The optimal working temperature range is between 5°C and
35°C.
2. If you notice any black spots on the projection screen, please don't worry. Simply contact
us at [e-mail] and we will provide a video tutorial on how to remove dust
particles.
3. To prevent damage to the projector, it is crucial to protect it from strong impact, extrusion,
and vibration. Avoid moving the device during operation, as this can lead to internal circuit
faults.
4. The lens is a critical component of the projector that directly impacts picture quality. To
ensure optimal performance, it is important to keep the lens clean and free of dust. Use
a soft cotton cloth to gently wipe the glass lens surface, avoiding the use of abrasive
materials or hard cloths.
