Projection Distance and Screen Size
■ The projection lens used in this projector is a 1.5 : 1, short focal-distance lens (with a manual shift function).
■ The range of projection distances that can be focused is 60” screen (approx. 1.76 m) to 150” screen (approx. 4.499
m) when the aspect ratio of the screen is 4:3.
■ With this projector, the projection screen can be shifted up and down in position within the range of approx. 30% to
55%. The amount of shift shown in the illustration is 50% shifting which corresponds to the factory setting. See
page 17 for “Setting the Amount of Lens Shifting”.
Screen
When the amount of shift is
selected to be 50% (factory
setting), set the screen so that its
bottom edge is the same height as
the center line of the lens.

■ Relationship between Projection Distances and Projection Screen Sizes
* The projection screen sizes (recommended) and projection distances listed above are only for a guide. Use them as
reference when setting the projector.
* This projector is designed to allow the screen size to be fine-adjusted approx. ±2%. The above listing shows the values
with ±0% adjustment (standard).
