When the lens is attached to the projector and

images are being projected onto the screen, the

peripheral focus may be out of focus in some

localized areas. If this happens, insert the spacer

in between the lens attachment and the lens to

correct the focus.

Correcting the focus

Thickness; 0.1 mm

Inserting the spacers corrects the distance for best

diagonal focus at the screen.

The corrected distance is determined by the

thickness of the spacers that are used. As a guide,

the distance is adjusted by approximately 30 mm

for each 0.1-mm thickness of the spacers.

There are three types of spacers provided, and

there are four of each spacer type. Use these

spacers to correct the distance as required.
