2. Installation and Connections
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 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 cover the vents
on the side or the front of the projector.
Reflecting the Image
Using a mirror to reflect your projectors image enables
you to enjoy a much larger image. Contact your NEC
dealer if you need a mirror system. If youre using a mir-
ror system 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 37.
