Attention

The lens may become damaged by hitting with a hard object or by wiping the front surface of the lens with excessive force. Handle with
care.
Note

Dust may accumulate around the air intake port depending on the environment or usage conditions such as when using the projector in a
dusty place. If the projector is used in such environment, the circulation of ventilation, cooling, and heat exhaust may weaken, causing the
luminance to dimmer.
