Installing the Projector (Cont.)

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”.

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.

*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).
