Reflecting the Image
Using a mirror to reflect your projector's image enables you to enjoy a
much larger image. Contact your 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-27.)
WARNING
* Installing your projector on the ceiling must be done by a quali-
fied technician. 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 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.
