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 or the front of the projector.
If your projector is mounted on the ceiling and your image is
upside down, use the “Menu” and “Select” buttons on your pro-
jector cabinet or your remote control to correct the orientation.
(See page E-35.)
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 E-35.)
