Standard Setting-up Positions
The screen should be positioned so that it is not directly touched by sunlight or room light as this will wash out the
colors of the picture making it hard to see. When possible, close all blinds, curtains, etc. and dim the lights. Also,
the LCD Projector should be at a 90° angle to the screen for the best picture results. To determine the distance for
the desired size, please refer to the LCD Projector/Screen Relationship Chart below.

Caution: When you set up the LCD Projector
Do not place it in humid or dusty places, or places where the air is sooty or full of cigarette smoke. If the lens,
mirror, or other optical components become dirty, the picture will blur or darken, making viewing difficult.
Do not expose to extreme heat or cold. Operating temperature: 5°C – 40°C (41°F – 104°F)
