Setting up
You can adjust the projection size with 1.2x 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. (Unit: m)
* The results above are approximate and may differ slightly from the actual measurements.

NOTE:
• 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.
