2. INSTALLATION

This section describes how to set up your MultiSync LT150/LT85 projector and how to connect video and audio sources.

Setting up Your Projector

Your MultiSync LT150/LT85 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.

Ensure that the power cable 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 projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 36" (0.9 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 200" (5.1 m) when the projector is about 22 feet (6.6 m) from the wall or screen.

Screen and Projection Distance

The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.
