SAFETY INSTRUCTIONS

Warning

For safety, do work in accordance with the

Exchange Manual to install this product.

Please read this manual and manuals for the

LCD projector to be used thoroughly to ensure correct usage through understanding. Incorrect

usage could result in ﬁ re, an injury or damage.

Do not give any shock or impact.

Any shock or impact could result in an injury or damage. The lens part is projected. Take care not to strike it.

NOTE

Take care of the lens.

When carrying it, protect the lens parts with lens cap. Do not scratch and polish the lens with hard object. Do not touch the lens to prevent fog or dirt of the lens

that cause deterioration of display quality.

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.

See the Projection Distance table in this user's manual

for information on optional lens projection distances.

In order to optimize keystone distortion correction

(trapezoidal distortion correction), make note of the [Lens Type] shown on the label of the optional lens to be used and select this lens type on the LCD Projector's option menu.

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 speciﬁ cations 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.

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.

Continued use with dust inside may result in ﬁ re or electric shock.

Caution

When replacing the lens, do not touch the LCD panels or polariz-

■

ing plates of the LCD projector or subject them to shocks.

This can cause damage to the equipment. It can also cause a misalignment of the optical adjustment and, therefore, require readjustments.

When replacing the lens, be careful not to damage the

connectors or wires inside the LCD projector.

This can cause damage to the equipment. Be careful not to pull on the connectors or wires or get them caught in the circuit board or case.

After replacing the lens, part of the lens and louver

■

(Only for models LENS-037 and LENS-038) may stick out from the LCD projector.

Transporting the LCD projector in the original projector shipping box can cause damage to the equipment.

Follow these Instructions

Do not touch the lens directly with your hands or ﬁ ngers.

■

This can dirty the lens and cause deterioration in image quality.

The lens is a precision optical device. Carefully handle the

■

lens without subjecting it to shocks or vibrations. When resting the lens on a surface, place the lens face
