This section describes how to set up your LT75Z projector and how to connect video and audio sources.
Setting up Your Projector
Your LT75Z 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
30" (0.8 m) measured diagonally when the projector is roughly 4 feet (1.3m) from the wall or screen. The largest the image can be
is 200" (5.1 m) when the projector is about 30 feet (9.2m) 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.
