Vidikron Vision Model 50 Owner’s Operating Manual
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 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 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. (The Model 50 has a lens throw ratio of between
1.82 and 2.42.)
Other Considerations
Throw Distance
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 50 has a throw distance range of between 174.72 inches
(4.44 meters) and 232.32 inches (5.90 meters).
