Installing the Projector
Projection Distance and Screen Size
•This projector uses 1.3x manual zoom lens for projection.
•The range of projection for good focus is approximately 1.6m to approximately 12m when the aspect ratio of the screen is 4:3. Install the projector within this range.
•If the KEYSTONE is adjusted, the screen becomes smaller. (☞ page 29)
