WARNING
• Installing your projector on the ceiling must be done by a quali-
fied technician. Contact your NEC dealer for more informa-
tion.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the projec-
tor 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 104˚F (40˚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.
If your projector is mounted on the ceiling and your image is upside
down, use the “Menu” and “Select” buttons on your projector cabi-
net or ▲▼ button on your remote control to correct the orientation.
(See page E-23.)
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-23.)
