2. INSTALLATION
This section describes how to set up your MultiSync MT1055/MT1050/
MT850 projector and how to connect video and audio sources.
Setting up Your Projector
Your MultiSync MT1055/MT1050/MT850 Projector is simple to set up
and use. But before you get started, you must first:
1. Determine the image size.
2. Set up a screen or select a non-glossy white wall onto which you
can project your image.
Carrying the Projector: Always carry your projector by the handle.
Ensure that the power cable and any other cables connecting to video
sources are disconnected before moving the projector.
When moving the projector or when it is not in use, cover the lens with
the lens cap.

Attaching the lens cap to the lens hood
with the supplied string and rivet.
Selecting a Location
The further your projector is from the screen or wall, the larger the
image. The minimum size the image can be is approximately 30 (0.76
m) measured diagonally when the projector is roughly 4 feet (1.3 m)
from the wall or screen. The largest the image can be is 300 (7.6 m)
when the projector is about 36.8 feet (11.2 m) from the wall or screen.
Using a Tabletop or Cart
1. Place your projector on a flat level surface at the optimal dis-
tance from the screen or wall so you realize the size image you
want. 
(Avoid having bright room lighting or sun light directly on the screen
or wall where youÕll be projecting the image.)
2. Connect the power cable, remove the lens cap and turn the pro-
jector on. 
(If no input signal is available, the projector will display a
background image.)
3. Ensure that the projector is square to the screen.

String
4. Move the projector left or right to center the image horizontally
on the screen.
5. To center the image vertically, lift the front edge of the projector
and press the One-Touch Tilt button on the front-left side of the
projector to release the Front Adjustable foot.

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

verely damaged.
¥ Do not use the projector where temperatures vary greatly. The
projector must be used at temperatures between 32ûF (0ûC)
and 104ûF (40ûC).
¥ Do not expose the projector to moisture, dust, or smoke. This
will harm the screen image.
¥ Ensure that you have adequate ventilation around your projec-
tor so heat can dissipate. Do not cover the vents on the side or
the front of the projector.If your projector is mounted on the ceiling and your image is upside
down, use the ÒMenuÓ and ÒSelectÓ buttons on your projector cabinet or
st button on your remote control to correct the orientation. (See page
E-36.)
Reflecting the Image
Using a mirror to reflect your projectorÕs image enables you to enjoy a
much larger image. Contact your NEC dealer if you need a mirror. If
youÕre using a mirror and your image is inverted, use the ÒMenuÓ and
ÒSelectÓ buttons on your projector cabinet or st buttons on your re-
mote control to correct the orientation. (See page E-36.)
