Please don't place the projector in any of the following environments.
1. Space that is poorly ventilated or confined. Allow at least 20 inch clearance from walls and free flow of air around the projector. 2. Locations where temperatures may become excessively high, such as the inside of a car with all windows rolled up. 3. Locations where excessive humidity, dust, or cigarette smoke may contaminate optical components, shortening the projector's life span and darkening the image.
