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 EXIT to return to operational mode.
Press ADJUST to return to operational mode.
