Installation

Ambient Light  In general, minimize or eliminate light sources directed at the screen. Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant.

Other Considerations Other considerations and tips that can help improve your installation:

•Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may affect performance.

•Keep the projector away from devices that radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers and elevators.

Throw Distance Throw distance is the distance measured from your projector’s lens to the screen. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be of the right size for your screen.

You can quickly estimate the throw distance by taking the width of the screen and multiplying it by the lens throw ratio that is applicable to your projector:

•The Model 30 has a minimum throw distance factor of 1.38 and a maximum throw distance factor of 1.80.

•The Model 30ET has a minimum throw distance factor of 1.88 and a maximum throw distance factor of 2.45.

��

The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen.

For example, with an 8-foot (96-inch) wide screen (the maximum recommended screen width for this projector):

• The Model 30 has a throw distance range of between 132.48 inches (3.36 meters) and 172.80 inches (4.39 meters).

• The Model 30ET has a throw distance range of between 180.48 inches (4.58 meters) and 235.20 inches (5.97 meters).
