Adjusting projection image size
Refer to the graphic and table below to determine the screen size and projection
distance.
* Screen Diagonal (inch) = 40/1034* Projection Distance (mm)
Ex: 24=40/1034*621
** Screen Diagonal (mm) = 40*25.4/1034* Projection Distance (mm)
Ex: 610=40*25.4/1034*621
There is +/-10% tolerance among these numbers due to optical component variations.
Note
• Position the projector in a horizontal position; other positions can cause heat build-up
and damage to the projector.
• Keep a space of 30 cm or more between the sides of the projector.
• Do not use the projector in a smoky environment. Smoke residue may build-up on
critical parts and damage the projector or its performance .
• Consult with your dealer for special installation such as suspending from a ceiling.
