Cleaning Or Replacing The Filter
The air-filter sponge keeps the inside of the MultiSync MT600 LCD Projector free
from dust or dirt and should be cleaned after every 100 hours of operation (more often
in dusty conditions). If the filter is dirty or clogged, your projector may overheat.
NOTE:  Clean your filter after every 100 hours of operation.
To clean or replace the air-filter:
1. Turn off the LCD projector and wait for the fan to stop. Turn off the main power and
disconnect the power cable.
2. Remove the filter panel by pushing down on the cover until you feel it detach.
3. Replace it with a new filter or vacuum the filter thoroughly. Do not wash the filter
with soap and water. Soap and water will damage the filter membrane.
4. Reposition the filter or put the new filter into place. Reinstall the filter panel.

This section describes how to set up your MultiSync MT600 LCD projector
and how to connect video and audio sources.
Setting Up Your MultiSync MT600 LCD Projector
Your MultiSync MT600 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 ProjectorAlways 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.
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 20Ó (0.5m) measured diagonally when the projector is roughly 3.28 feet
(1.0m) from the wall or screen. The largest the image can be is 300Ó (7.6m)
when the projector is about 39 feet (12m) 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 youÕll
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 black screen.)
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.
5. To center the image vertically, lift the front edge of the projector and press
the buttons on the sides of the projector, just above the feet, to release the
one-touch tilt feet.
6. To fine tune the imageÕs position vertically on the screen, rotate each front
foot. (There is approximately 7° of up and down adjustment for the front of
the projector.)
7. Increase or reduce the size of the projected image by pressing the ÒZoomÓ
and (+) or (-) buttons on the remote control.
