Focusing the Screen Image
•••• If the surface of the lens is dirty or misted
over as a result of condensation, it may
not be possible to adjust the focus
correctly. If this happens, clean or de-mist
the lens. (p.46)
•••• If the projector is positioned outside the
normal projecting range of 0.9 - 13 m (2.9
- 42.6 ft.), it may not be possible to obtain
the correct focus. If you have trouble
obtaining the correct focus, check the
projection distance.
