TIP:
Calculation of the throw distance from the screen size (m)
PA600X/PA500X: H x 0.8 to H x 1.1 : 1.0 m (min.) to 10.9 m (max.)
PA550W: H x 0.8 to H x 1.0 : 1.0 m (min.) to 11.4 m (max.)
PA500U: H x 0.8 to H x 1.0 : 1.0 m (min.) to 11.3 m (max.)
* “H” (Horizontal) refers to the screen width.
* Figures differ by several % with the table above because the calculation is approximate.
Lens shifting range
The lens shift dials on the projector allow you to move the position of the projected image in the vertical and horizontal
directions based on the following ranges.
Description of symbols: V indicates vertical (height of the projected image), H indicates horizontal (width of the projected image).
For adjusting the lens shift, see the User’s Manual supplied with the projector.

1. Turn the focus ring clockwise or counterclockwise to focus on the projected image around the optical axis.
The drawing below shows an example when the projected image is shifted upward. In this case the optical axis is at the bottom
edge of the projected image.
Optical axis
* With the lens shift in the center position the optical axis is at the center of the image. In this case, adjust the focus
at the center of the projected image.

2. Turn the edge focus ring clockwise or counterclockwise to adjust the focus at the edges of the projected image.
Doing so will not affect the focus adjustments around the optical axis done at Step 1.
Optical axis
This completes adjusting the projected image’s overall focus.
