TIP:

Calculation of the throw distance from the screen size (m)

PX750U: H x 0.75 to H x 0.93 : 0.62 m (min.) to 10.41 m (max.)

PX700W: H x 0.79 to H x 0.98 : 0.65 m (min.) to 10.91 m (max.)

PX800X: H x 0.77 to H x 0.97 : 0.61 m (min.) to 10.16 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

Button operations on the projector or on the remote control 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 pro-

jected image).

For adjusting the lens shift, see the User’s Manual supplied with the projector.

Adjusting the focus

1. Focus on the projected image around the optical axis. (Powered focus)

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.

Adjusting with buttons on the cabinet

Use the FOCUS (+) or (-) button on the projector cabinet.

Adjusting with the remote control

Hold the CTL button and press the VOL/FOCUS +/− button.

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.
