For the best quality of the projection image, install a screen where sunlight or room light does not shine directly
onto the screen. Close window shades or curtains to block the light and turn off the lamps.
Do not use the projector at a raised or a horizontally tilted position. Doing so may cause malfunction of the

projector.
You can tilt the projector body approximately ±30 ° vertically and ±10 °
horizontally.
Overtilting may result in shortening the component’s life.
Do not cover the air outlet port and air intake ports or place anything within
