WARNING
• Only use your LCD 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 LCD projector where temperatures vary
greatly. The projector must be used at temperatures be-
tween 0˚C (32˚F) and 40˚C (104˚F).
• Do not expose the LCD projector to moisture, dust, or
smoke. This will harm the screen image.
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 (▲) (▼) buttons on your remote control
to correct the orientation. (See page E-27.)
Reflecting The Image
Using a mirror to reflect your LCD projector's image en-
ables 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 remote control to correct the orien-
tation. (See page E-27.)
Rear Screen Projection
You can use your MultiSync MT1020G/820G LCD projec-
tor to project an image from the rear onto a transparent
screen. The distance the projector must be from the screen is
the same as if you were projecting the image from the front.
Contact your NEC dealer if you need a transparent screen.
If you're projecting the image from the rear and your image
is inverted, use the “Menu" and "Select" buttons on your
projector cabinet or (▲) (▼) buttons on your remote control
to correct the image. (See page E-27.)

• Ensure that you have adequate ventilation around your
LCD projector so heat can dissipate. Do not cover the
vents on the bottom or the side of the projector.
Ceiling Installation
Installing your MultiSync MT1020G/820G LCD Projector
on the ceiling must be done by a qualified technician. Con-
tact your NEC dealer for more information.
Do not attempt to install the projector yourself.
• An optional ceiling mount kit MT810/1000 CMKIT
manufactured by NEC is recommended.
