Ceiling Installation
WARNING
* Do not attempt to install the projector yourself.
17.1
• Only use your projector on a solid, level surface. If the projec-
17.0
tor falls to the ground, you can be injured and the projector
17.1
severely damaged.
17.1
• Do not use the projector where temperatures vary greatly. The
17.1
projector must be used at temperatures between 32˚F (0˚C)
17.1
17.1
and 95˚F (35˚C).
17.2
• Do not expose the projector to moisture, dust, or smoke. This
17.2
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.
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-40.)
