WARNING
* Installing your 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.
• 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 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
projector so heat can dissipate. Do not cover the vents
on the side 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 your remote control
to correct the orientation. See page 86.
