Distance Chart
Throw Distance and Screen Size
The following shows the proper relative positions of the projector and
screen. Refer to the table to determine the position of installation.
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.
• 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 41˚F (5˚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.
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
왖왔
buttons on your re-
mote control to correct the orientation. (See page E-41.)
NOTE:
A 16:9 image is supported within the limits of the above values.
