Keystone correction (trapezoidal distor tion correction)

may be limited with some lenses.

LENS-037 Notes on Use

When using this optional lens, adjust the projected image
position using the following procedure.
1. Adjust the up-down lens shift dial to the DOWN direction

(same for ceiling installations).

2. Adjust the left-right lens shift dial to the center position.
* Adjusting the lef t-right lens shif t dial to shif t the lens

to the left end or right end may cause the shading at a
corner area (*1) as shown in the illustration below. This
lens cannot display the projected image properly in these
areas, so adjust the left-right lens shift dial not to have the
shading in the projected image.

(*1) The corner area of the projected image may appear

dark, or be shaded.
