WARNING

Only use your LCD projector on a solid, level surface. If the projector falls to the ground, you can be injured and the projector severely damaged.

Do not use the LCD projector where temperatures vary greatly. The projector must be used at temperatures between 32˚F (0˚C) and 104˚F (40˚C).

Do not expose the LCD projector to moisture, dust, or smoke. This will harm the screen image.

Ensure that you have ad- equate ventilation around your LCD projector so heat can dissipate. Do not cover the vents on the bottom or the side of the projector.
