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.

Screen size = diagonal(inch)

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.

Ceiling Installation

Installing your MultiSync MT1020/MT820 LCD Projector on the ceiling must be done by a qualified technician. Contact your NEC dealer for more information.

Do not attempt to install the projector yourself.

NOTE : Distances may vary ± 5%.
