Setting up
You can adjust the projection size with 2.0x zoom lens. Calculate and define the throw distance as follows.
* All measurements above are approximate and may differ slightly from the actual measurements.

Calculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal.
SW (m) = SD (") x 0.0215
SH (m) = SD (") x 0.0135
LW (m) = 0.0289 x SD (") - 0.046
LT (m) = 0.0576 x SD (") - 0.061
* The results above are approximate and may differ slightly from the actual measurements.

NOTE:
• See page 50 for the screen size and throw distance of 4:3/16:9.
• Do not use the projector at a raised or a horizontally tilted position as it may cause
malfunction of the projector.
• Make sure the projector lens surface is parallel with the screen. You can tilt the projector
body approximately ± 30° vertically. Overtilting may result in shortening the component’s
life.
• For the best quality of the projection image, install a screen where sun light or room light does not shine directly onto the
screen. Close window shades or curtains to block the lights.
