Optical Lens Focusing
The optical focusing procedure is performed separately for each
lens. The appropriate CRT will be switched on as the user proceeds
through the optical focusing adjustment sequence.
Each lens has two focus adjustment points, one at the rear of the lens
and one at the front. The center of the projected image is focused by
loosening the wing nut at the rear end of the lens and rotating the
lens barrel until the center of the image is clearly focused. The corners
of the projected image are focused by loosening the wing nut at the
front end of the lens and rotating the lens barrel until the corners of
the image are clearly focused. Repetition of these adjustments may
be necessary to optimize optical focusing.
Press
ENTER
to continue. After finishing focusing of the three lenses,
press
ENTER
to enter the Raster centering.
Press
