This section describes how to set up your MultiSync MT830/1030 LCD
projector and how to connect video and audio sources.
Setting Up Your MultiSync MT830/1030 LCD
Projector
Your MultiSync MT830/1030 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
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. )
INSTALLATION
33
34 6. If a trapezoidal distortion appears on the screen, use the KEY-
STONE button on the remote control or select Keystone from the
menu to correct the distortion.
If necessary, adjust the front or rear feet so that the lens surface is
parallel to the screen. If you use the projector with the screen tilted,
the picture will be distorted. Each of the rear feet height can be
changed up to 0.6 (4 mm).
7. Increase or reduce the size of the projected image by pressing the
Zoom (+) or (Ð) buttons on the remote control or top of the
cabinet.
