Caution: Maximum five (5) seconds are allowed of minimum light output on an non-adjusted integration rod. Otherwise, the
sealing between the DMD's and the prism will be damaged.
5. Activate the lamp and zoom the projector lens in or out until the projected image is focused.
Note: Dialog windows must be displayed sharp instead of blurry. This is independent of the focus of the light beam.
6. Gently rotate the adjustment ring D back or forward to a position which projects the sharpest possible edges on the screen.
Tip: Place a 2 mm Allen key in one of the holes on the outer side of the adjustment ring (D). The Allen key function as an
extension bar of the adjustment ring. This allows a more precise adjustment.
