I Relationship between Projection Distances and Projection Screen Sizes
Notes
• The relationship between the projection distances and projection screen sizes differs depending on the lens unit (optional)
you are using.
• The projection distance and projection screen sizes listed here are only for a guide. Use them as reference when setting the
projector.
