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 re-

mote control to correct the orientation. (See page E-46.)

WARNING
* Installing your projector on the ceiling must be done by a quali-

fied technician. Contact your NEC dealer for more information.

* Do not attempt to install the projector yourself.

• To avoid premature lamp failure, do not tilt the front of the projector

up or down by more than 75° from level. Tilting the front of the projec-
tor up or down from 15° to 75° might reduce lamp life by up to 25%.

• Only use your projector on a solid, level surface. If the projector falls

to the ground, you can be injured and the projector severely dam-
aged.

• Do not use the projector where temperatures vary greatly. The pro-

jector 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.
