Tip
When keystone correction is carried
out, the projected image will become
smaller.
The keystone correction settings are
memorized, so that if you change the

need to readjust the keystone correction
settings.
To return an altered keystone correction
setting to the factory default setting, do
the following.
To restore the vertical keystone correction
to the default setting: While holding down
the
button, press the
button for
1 second or more.
To restore the horizontal keystone
correction to the default setting: While
holding down the
button, press the
button for 1 second or more.
If the images become uneven in
appearance after keystone correction is
carried out, decrease the Sharpness
setting.

Press
on the projector's control panel to correct the keystone distortion.
If using both horizontal and vertical keystone correction,
carry out in the following order.
1 . With the front adjustable foot retracted, set the projector so that it is fully horizontal.

3 . Adjust the vertical keystone distortion until both sides of the picture are vertical.
