I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
a. Focus Adjustment
1) Confirm that each of the pixels in the nine portions are clearly visible.

Note: If the Projection Lens is twisted left, the Focus Screen twists left. If the Projection Lens is twisted right, the Focus Screen twists right. 3) Tighten the 4 Screws while fixing the Projection Lens.
