WARNING
* Installing your projector on the ceiling must be done by a
qualified technician. Contact your NEC dealer for more in-
formation.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the pro-
jector falls to the ground, you can be injured and the projec-
tor 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 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-37.)
