If the LCD projector and the screen are not properly placed, the picture will be distorted producing a keystoned image as shown at right.

Caution: When setting 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 component becomes dirty, the picture will blur or darken, making viewing difficult.

Do not expose the projector to extreme heat or cold. Operating temperature: 41°-104°F (5°-40°C).
