							This section describes how to set up your MultiSync LT100 projector and how
to connect video and audio sources.
Setting Up Your MultiSync LT100 Projector
Your MultiSync LT100 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 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 229
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 24
(0.61 m) measured diagonally when the projector is roughly 4 feet (1.2 m)
from the wall or screen. The largest the image can be is 300 (7.6 m) when
the projector is about 40.35 feet (12.3 m) from the wall or screen.
