If your projector is mounted on the ceiling and your image is upside down, use the "Menu" and "Select" buttons on your projector
cabinet or LM button on your remote control to correct the orientation. (See page E-36.)

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 LM buttons
on your remote control to correct the orientation. (See page E-36.)

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 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 projector so heat can dissipate. Do not cover
the vents on the side or the front of the projector.
