Model LENS-037 (Fixed Short Throw Lens) Cleaning

Use commercially available lens tissue to clean the lens (used to clean cameras, eyeglasses, etc.).

Excepting for lens, use a soft cloth to clean. When excessively soiled dilute a neutral detergent in water, wet and wring out the soft cloth.

Do not use detergents or chemicals other than those noted above (e.g. benzene or thinners).

OPERATIONS

Project an image as described in the LCD Projector user's manual, and adjust the size and focus of the projected image.

LENS-037 Notes on Use

When using this optional lens, adjust the projected image position using the following procedure.

1.Adjust the up-down lens shift dial to the DOWN direction (same for ceiling installations).

2.Adjust the left-right lens shift dial to the center position.

*Adjusting the left-right lens shift dial to shift the lens to the left end or right end may cause the shading at a corner area (*1) as shown in the illustration below. This lens cannot display the projected image properly in these areas, so adjust the left-right lens shift dial not to have the shading in the projected image.

(*1) The corner area of the projected image may appear dark, or be shaded.

For more information see the "Lens Type"of the "Service" item of the "Settings Menu" in the LCD Projector user's manual.

NOTE

The distance of projection may not allow focusing on the peripheral area of the screen. Adjust the focus to keep the center and the peripheral area of the screen balanced.

This specifications are subject to change without notice. The zoom lens may cause some distortion of the image on the screen depending on the zoom position.

Distortion may appear on screen if the keystone correction (trapezoidal distortion correction) is overly adjusted. Keystone correction (trapezoidal distortion correction) may be limited with some lenses.
