E–20

WARNING

* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the projec-

tor 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 32˚F (0˚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 pro-

jector so heat can dissipate. Do not cover 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 you 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-40.)
