Installation
Focus correction
When the lens is attached to the projector and images are being projected onto the screen, the peripheral focus may be out of focus in some localized areas. If this happens, insert the one, of three sizes of spacers, in between the Lens Attachment and the lens to adjust the focus.
Inserting the Spacer corrects the distance on the Lens Adjustment and improves the diagonal focus. The corrected distance is determined by the thickness of the used spacers. As a guide, the distance is adjusted by approximately 30 mm for each
There are three types of spacers provided, and there are four of each spacer type. Use these spacers to correct the distance as required.
| Spacer "1" | Correction distance |
| Color; Clear | 30 mm/for |
| Thickness; 0.1 mm | projection |
| Spacer "2" | Correction distance |
| Color; Black | 55 mm/for |
| Thickness; 0.2 mm | projection |
| Spacer "3" | Correction distance |
| Color; Cream | 80 mm/for |
| Thickness; 0.3 mm | projection |
