Adjusting the Image Size (Zoom Function)

projector itself has been set up.

•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. sp.77, p.84
•If the distance from the lens to the screen is not within the
recommended distance, it is impossible to bring the lens into focus.
