Lens shift range
About lens position
The projection distance and lens shift range
are measured with the lens position adjusted
to the center. To adjust the lens position to
the center, follow the procedures below:
1 Rotate the left lens shift dial clockwise
or counterclockwise then align the
lens fixing screws with the v V marks
in four places, as illustrated, for
adjusting the lens horizontally.
2 Rotate the right lens shift dial
clockwise until the lens is fixed, to
adjust the lens vertically.
Before adjusting the lens position to the center
and checking whether the lens position is
centered, turn off the power to prevent
projected light from entering the eyes.
