3. Adjusting the lens

AUTION

Before shifting the lens, make sure that the lens locking system is not engaged! See the User

guide of the projector for details on the lens locking system.

How to adjust the focus ?

1. Turn the lens focus ring so as to obtain an overall focussed image

The use of a sheet of paper held in front of the screen can be useful to determine the focus plane (position
for best focus)

Unsharp corners in the image can be adjusted with the Sheimp

ug adjustment (3 adjustment screws on the

lens holder), see the Installation section

Before adjusting the lens focus, insure that the Back Focal Length is correctly adjusted, "Back focal length
adjustment", page 9
