4. Maintenance
4.1 Lens Care
- Do NOT use fingers or a general cloth to clean the projector lens.
- Use a specialized lens cleaning cloth and solution designed for optical surfaces.
- Gently wipe the lens to remove dust or smudges.
4.2 General Cleaning
- Wipe the exterior of the projector with a soft, dry cloth.
- Avoid using abrasive cleaners or solvents.
- Ensure ventilation ports are clear of dust and obstructions.
5. Troubleshooting
5.1 Image Clarity Issues
- Uneven Clarity: The brightness and clarity of the central area of the projection may differ from the four corners. This is a normal phenomenon for projectors, especially noticeable with text. For movies, the difference is usually negligible. If 100% uniform clarity across the entire screen is required, consider a TV or monitor instead of a projector.
- Fog on Lens: Due to material and temperature differences, some lenses may develop fog upon receipt. This is normal and typically disappears after a few days of use.
- Lines on Lens: Concentrated light and reflection may cause visible lines on the lens when the projector is off. These are not scratches and will disappear when the projector is turned on.
5.2 Language and Content Access
- If you require languages other than Chinese or English, or wish to access a wider range of international apps, connect an external TV stick or TV box to the projector.

8. User Tips
- External TV Box: To fully enjoy international content and apps, consider using a dedicated TV box (e.g., Google TV, Apple TV, Amazon Fire TV Stick) connected via HDMI. This bypasses any regional restrictions or language limitations of the projector's native OS.
- Optimal Viewing: For the best picture quality, use the projector in a dimly lit or dark room. A dedicated projector screen will also enhance image vibrancy and contrast compared to a plain wall.
- Sound Enhancement: While the built-in Harman Kardon speakers are excellent, for a truly cinematic audio experience, consider connecting external sound systems via the eARC HDMI port or Bluetooth.
- Regular Cleaning: Keep the lens and ventilation areas clean to ensure optimal performance and longevity of the projector.
