INSTALLATION AND CONNECTIONS ⬎ Setting Up the Screen and theProjector

WARNING

* Installing your projector on the ceiling must be done by a qualified tech-

nician. Contact your NEC dealer for more information.

* Do not attempt to install the projector yourself.

• Only use your 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 projector where temperatures vary greatly. The projector
must be used at temperatures between 41˚F (5˚C) and 95˚F (35˚C).

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

• Ensure that you have adequate ventilation around your projector so
heat can dissipate. Do not cov er the vents on the side or the front of the
projector.

Reflecting the Image

Using a mirror to reflect your projector's image enables you to enjoy a
much larger image. Contact your NEC dealer if y ou need a mirror . If you're
using a mirror and your image is inverted, use the MENU and SELECT
buttons on your projector cabinet or  buttons on your remote control to
correct the orientation. (See page E-95.)
