NEC iS8-2K Installation And Adjustment Manual page 36

Loosen each of the two y-direction setscrews of
the anamorphic lens holder and turn the y-direc-
tion adjusting knob on the top to adjust the lens
position so that the image is projected through
the center of the anamorphic lens. Securely
tighten the two setscrews after adjustment.
Unlock the x-direction fixing levers to adjust the
lens position so that the image is projected
through the center of the anamorphic lens. Se-
curely lock the levers after adjustment.
(The image center on the screen must match with and without the
anamorphic lens.)
Loosen the two tilt angle fixing screws and turn
the tilt angle adjusting knob (see the illustration
below) to adjust the angle so that the projected
image becomes as illustrated below. Securely
tighten the screws after adjustment.
Note:
Be careful not to allow the anamorphic lens to get into con-
tact with the primary lens when the former is tilted. If the
two lenses eventually meet, repeat step (2) above.
