Epson EMP-53 사용자 설명서

The projector should be set up so that it is as perpendicular to the screen as 
possible.

If it is not possible to set up the projector so that it is perpendicular to the 
screen, it can be set up at a slight vertical angle instead. You can extend or 
retract the front adjustable feet to adjust the upward projection angle 
within a maximum range of 10°.
When the projector is tilted vertically, it will cause keystone distortion to 
appear in the image. However, the projector is equipped with an automatic 
keystone correction function that can automatically correct this keystone 

distortion as long as the vertical angle of tilt is within a range of 
approximately 15º *. Automatic keystone correction is carried out 
approximately one second after the projectors power is turned on and the 
projector has been positioned.

* This value applies when the zoom ring is turned to the maximum "T" 

setting. If the zoom ring is turned to the "W" setting, the available angle 
of tilt for automatic adjustment will become smaller.
