Matters Needing Attention

1. Because the projector and lens parts contain precision parts, please do not vibrate or overload the projector or lens parts violently.
2. When transporting a projector with a lens, the lens needs to be removed before transportation. Improper handling during transportation may damage the lens and lens displacement system.
3. Before removing or installing the lens, be sure to turn off the projector, wait until the cooling fan stops, and unplug the power cord.
4. Please do not touch the lens surface when removing or installing the lens.
5. To prevent fingerprints, dust or oil from adhering to the lens surface, please do not scratch the lens surface.
6. When using the lens part, set the lens displacement to the center of the screen.
7. Adjusting the lens displacement to a position other than the center position may make the edge of the image dim or cause black shadows. Please adjust the displacement to avoid black shadows.

Packaging & Shipping



We all use corrugated boxes or explosion-proof flight boxes tailored for the lens. Two layers of pearl bubble film are placed in the lens box to absorb shocks, better protect the lens, and avoid bumps during transportation, ensuring that each of our customers received the lens in perfect condition.
