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.
