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
Spacer "1"

Inserting the spacers corrects the distance for best
diagonal focus at the screen.
The corrected distance is determined by the thick-
ness 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.
