NOTE:
• In terms of the optical characteristics of this projector, in addition to keystone distortion
(page E-11), there may be occurrences of slight pincushion type or barrel type distortion.
To adjust the projected image with the screen, first perform Steps 1 to 6 pages E-7 to E-9
(Adjustment of the projection distance → Height adjustment of the projected image → Fo-
cus adjustment), then align the 4 corners of the projected image with the 4 corners of the
screen. Following this, if the pincushion type or the barrel type distortion is conspicuous,
please perform "7. Adjusting Pincushion or Barrel Distortion (Pincushion)" on the next page.
• If the keystone distortion is not improved after pressing the FOCUS buttons and adjusting
the focus, or the aspect ratio does not agree, check the screen or projector are not on a tilt.
[Symptom1]
In the case of keystone distortion (as illustrated), either the
screen is directed slightly upward or the projector is directed
slightly upward.
[Action]
Tilt the top end of the screen to the front or rotate the front
feet of the projector to correct keystone distortion.
