Correction Function
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 adjust the
upward projection angle of the projector to a maximum of 12° and the
downward projection angle to a maximum of 4° by extending and
retracting the front adjustable foot and rear adjustable feet.
