							This section describes how to set up your MultiSync MT1020/MT820 LCD
projector and how to connect video and audio sources.
Setting Up Your MultiSync MT1020/MT820
LCD Projector
Your MultiSync MT1020/MT820 LCD 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 LCD Projector Always carry your LCD projector by the
handle. Ensure that the power cord 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.
INSTALLATION 2
Carrying handle
Pull out
Selecting A Location  The further your LCD projector is from the screen or
wall, the larger the image. The minimum size the image can be is approxi-
mately 20 (0.5 m) measured diagonally when the projector is roughly 3 feet
(1.0 m) from the wall or screen. The largest the image can be is 300 (7.6 m)
when the projector is about 40.03 feet (12.2 m) from the wall or screen.

							Using A Tabletop Or Cart
1. Place your LCD projector on a flat level surface at the optimal
distance 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 youll be projecting the image.)
2. Connect the power cable, remove the lens cap and turn the projector
on. (If no input signal is available, the projector will display a
background image.)
3. Ensure that the projector is square to the screen.
4. Move the projector left or right to center the image horizontally on
the screen. (A)
5. To center the image vertically (B), lift the front edge of the projector
and press the buttons on the front of the projector, just above the
feet, to release the one-touch tilt feet. (There is approximately 10.5û
of up and down adjustment for 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 (s) (t)  buttons on your
remote control to correct the orientation. (See page 60.)
Reflecting The Image
Using a mirror to reflect your LCD projectors image enables you to enjoy a much
larger image. Contact your NEC dealer if you need a mirror.
If youre using a mirror and your image is inverted, use the ÒMenuÓ and ÒSelectÓ
buttons on your projector cabinet or (s) (t) buttons on your remote control to correct
the orientation. (See page 60.)
Rear Screen Projection
You can use your MultiSync MT1020/MT820 LCD projector 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 youre projecting the image from the rear and your image is inverted, use the ÒMenu
and Select buttons on your projector cabinet or  (s) (t) buttons on your remote
control to correct the image. (See page 60 .)

     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 between 32ûF (0ûC) and 104ûF (40ûC).
¥ Do not expose the LCD projector to moisture, dust, or smoke. This will harm the screen image.
¥ Ensure that you have ad-
equate 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
MT1020/MT820 LCD Projec-
tor on the ceiling must be done
by a qualified technician. Con-

							3. Use the MultiCable thats supplied to connect your PC or Macintosh computer to the
LCD projector. For a PC, use the smaller 15-pin connector on the cable to connect to
your computers video port; use the larger 15-pin connector on the cable to connect
to the projectors RGB 1 input. For Macintosh, use the larger 15-pin connector on the
cable to connect to your computers video port; use the smaller 15-pin connector on
the cable to connect to the projectors RGB 2 input. (You can also use your own
video cable if you wish. For a PC cable, use the smaller 15-pin connector RGB 2 on
the projector. For a Macintosh cable, use the larger 15-pin connector RGB 1 on the
projector.)
4. Turn on the LCD projector and the computer.
5. If the projector goes blank after a period of inactivity, it may be caused by a  screen
