WARNING
• Installing your projector on the ceiling must be done by a qualified techni-
cian. Contact your 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 projec-
tor.
Reflecting the Image
Using a mirror to reflect your projector’s image
enables you to enjoy a much larger image. Con-
tact 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 pro-
jector cabinet or
▲▼ buttons on your remote con-
trol to correct the orientation. (See page E-31.)
