Optical Engine Adjustment

The optical engine needs to be aligned when the vertical or horizontal images do not cover the screen or
are tilted.
Note: Before continuing with this adjustment, move the arm assembly up and down to relieve any stress and

see if the arm will realign itself and project an aligned image.

1. Locate the access door on the under side of the

projection arm.

2. Slide the door release catch to the open position

using the blade of a small screwdriver. Carefully
lift outward to remove the optical engine door.

3. Locate adjustment screw for side to side screen

adjustment. Locate locking screw for side to side
adjustment.
