Adjusting the Focus
This section describes how to adjust the video focus.
1.Turn the focus ring on the projector to adjust 
the focus.
Tip:
 Focus cannot be achieved if the lens is dirty or 
covered with condensation.  Wipe off any dirt 
or condensation (See page 64).
 If adjustment does not succeed, make sure the 
setup distance is between 39.37inches (1.0m)  
and 515.75inches (13.1m).
Keystone Correction (Using Projector Button)
When the foot adjust levers are used to change the projection angle, the 
keystone correction function can be used to correct trapezoidal distortion 
upward or downward by roughly 15°.
1.Press the Keystone button on the projector 
to minimize the trapezoidal distortion.
Tip:
 A keystone correction reduces screen size.
 The keystone correction is stored in memory.  
You will need to readjust the image if the 
projector is moved to a different location or the 
projection angle is changed.
 If a keystone correction makes the image 
noticeably uneven, reduce the video sharpness 
with the menu commands Video > Sharpness 
(See page 44).
