prevent the build-up of heat inside your projector. Allow at least 3 inches
(10cm) of space between your projector and a wall.

2. Prevent foreign objects such as paper clips and bits of paper from falling into
your projector. Do not attempt to retrie ve any objects that might fall into your
projector. Do not insert any metal objects such as a wire or scre wdr i ver into
your project. If something should fall into your projector, disconnect it
immediately and have the object removed by a qualified NEC service person.

3. Do not place any liquids on top of your projector.

• Do not look into the lens while the projector is on. Serious
damage to your eyes could result.

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.

INSTALLATION2

29

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.
