Adjusting the Screen Image
You can correct and adjust the screen images in order to obtain the best
possible pictures.
Adjusting the Image Size (Zoom Function)
The size of the projected images is basically determined by the distance
from the projector to the screen.
The following procedures explain how to adjust the screen images once the
projector itself has been set up.
PROCEDURE
Turn the zoom ring on the projector to adjust the image.
If a standard lens is fitted, the images can be enlarged in this way to
1.35 times the normal size.
If you would like to enlarge the images further, move the projector
further away from the screen.
Focusing the Screen Images (Focus Adjustment)
PROCEDURE
Turn the focus ring to adjust the image focus.
TIP

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.
• If using the standard lens and the projector is positioned outside the
normal projecting range of 77–1113 cm (2.5–36.5 ft.), it may not be
possible to obtain the correct focus. If you have trouble obtaining the
correct focus, check the projection distance. If an optional lens is fitted,
refer to the documentation for the optional lens for further details.
