Focusing the Screen Image

PROCEDURE
Turn the focus ring to adjust the image focus.
If keystone correction or Sharpness settings have been made, it may
not be possible to adjust the focus correctly.
TIP
• 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,
• If the distance from the lens to the screen is not within the
recommended distance, it is impossible to bring the lens into focus.
If you have trouble obtaining the correct focus, check the
projection distance. s
