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.

Electrical focusing
The electrical focus for red, green and blue is factory preset. When
they have to be readjusted, follow the procedure as described
below:
- Ensure the lenses are correctly focused.
- Open the top cover.
- Adjust separately the focus control for red and green for the
sharpest image on the screen.
Warning :
The blue focus has been factory adjusted for optimal color reproduc-
tion. Readjustment of the blue focus will effect color temperature and
color tracking.
Adjust only if really necessary. Mark first for future reference the
blue focus control before adjusting.
Focus adjustment should be done with hight contrast settings.
