NOTE:  Your  “Keystone”  correction  data  can  be  reset  by  pressing  and  holding 
the 3D REFORM button for a minimum of 2 seconds.
CAUTION:
Do  not  use  the  tilt-foot  for  purposes  other  than  originally  intended. 
Misuses such as using the tilt foot to carry or hang (from the wall or 
ceiling) the projector can cause damage to the projector.
The rear foot height can be adjusted up to 0.5 inch/13 mm.
Rotate  the  rear  foot  to  the  desired  height  in  order  to  square  the  image 
on the projection surface, but the vertical distance from the bottom to the 
desk  or  floor  should  be  0.5  inch  /13mm  to  make  the  projector  horizontal 
on the flat surface.

 Correcting Keystone Distortion
When the projector is not exactly perpendicular to the screen, keystone distortion occurs. To overcome it, you can use the 
“Keystone” function, a digital technology that can adjust for keys\
tone-type distortion, resulting in a crisp, square image.
The following procedure explains how to use the [K EYSTONE] screen from the menu to correct trapezoidal distortions.
When the projector is set up at an angle in relation to the screen, adju\
st the Horizontal option of the Keystone menu 
so that the top and bottom of sides of the projected image are parallel.\
Auto Keystone Correction
The Auto Keystone correction feature will correct vertical distortion of\
 a projected image on the screen. No special
operation required. Just put the projector on a flat surface.
To use the Auto Keystone function, first you must select [AUTO KEYSTON\
E] in [KEYSTONE] from the menu.
