Safety Tips
Key precautions
Environmental adaptation
The optimal projection distance is 1.5-4 meters (100-300 inches), and the ambient light needs to be less than 50lux to achieve the best HDR effect
Avoid use in areas above 3000 meters above sea level (due to limitations in cooling system design)
Maintenance suggestions
Clean the air inlet filter (located on the right side of the body) once a month to prevent overheating and frequency reduction
The system needs to maintain Android 11 or above version (security updates will stop from June 2025)
Compatibility Tips
Netflix 4K playback requires a certified HDMI cable (Belkin UltraHD recommended)
Apple device screen mirroring requires disabling the 'private WiFi address' function
