Read this rst! Always follow these precautions
WARNING:
Do not look at or place your skin into the light emitted from the lens while the
projector is being used.
Doing so can cause burns or loss of sight.
zStrong light is emitted from the projector’s lens. Do not look at or place your hands
directly into this light.
zTurn off the power when moving away from the projection lens or projector.
Do not project an image with the lens cover attached.
zDoing so can cause re.
CAUTION:
Before replacing the projection lens, be sure to turn off the power and
disconnect the power plug from the wall outlet.
zUnexpected projection of light may cause injury to eyes.
zReplacing the projection lens without removing the power plug may result in electric
shock.
Do not stand in front of the lens while the projector is being used.
Doing so can cause damage and burns to clothing.
zStrong light is emitted from the projector’s lens.
Do not place objects in front of the lens while the projector is being used.
Doing so can cause re, damage to the object, or malfunction of the lens and
projector.
zStrong light is emitted from the projector’s lens.
Do not open the desiccant bag. Do not eat the contents.
Inadvertently ingesting desiccant could be harmful.
zIf the desiccant gets into your eyes or mouth, immediately rinse with plenty of water
and seek medical attention.
zKeep desiccant out of the reach of children.

4-ENGLISH

Before Use

ENGLISH-5
Preparation
Before replacing the projection lens
Return the projection lens to the home position before replacing or removing it.
For details on how to return the lens to the home position, refer to the operating instructions
of the projector.
Attention
zMake sure that the projector power supply is switched off before attaching or detaching the
projection lens.
zAfter removing the projection lens, store it safely away from vibration or impacts.
z Do not touch the electrical contacts of the projection lens with your ngers. Dust and dirt on
the contacts may cause contact malfunctions, while static electricity may damage the unit.
zDo not touch the surface of the lens with bare hands. Finger prints and dirt on the surface
of the lens will be magnied by the lens and lower the quality of the projected image. Place
the supplied lens cover on the zoom lens when the projector is not in use.
zThe lens is made of glass. The lens could be damaged if brought into contact with or
rubbed against hard objects. Handle the lens carefully.
zUse a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use uffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
Attaching and Detaching the Lens
For details on attaching and detaching the projection lens, refer to the operating instructions
of the projector.

Preparation (continued)
Peripheral focus adjustment function (ET-D3LEW10C)
When yo u change the size of the projected image, the focal balance between the center
and peripheral areas of the screen may shift. This shift in balance tends to increase
proportionally with smaller throw ratios.
The ET-D3LEW10C is equipped with a peripheral focus adjustment function to correct
the shift
in focal balance between the center and peripheral areas of the screen.
1) Operate the projector to align
the focus of the center of the
projected image.
2) Loosen the lock knob by
turning it counterclockwise.
Note
zThe screen sizes displayed on the lens are approximate guides.
3) Turn the peripheral focus
adjustment ring in the
directions of the arrows
to align the focus of the
peripheral areas of the image.
4) Tighten the lock knob by
turning it clockwise.
The illustrations in this procedure depict
use of the PT-SRZ21KC as an example.

Note
zThe illustrations of projectors in this manual are for informational purposes only and do not
represent a specic projector model. Congurations may vary with the model.
Attention
zTo prevent obstruction of the intake and exhaust vents, install the projector with a
clearance at least 500 mm (1 ft. 7 in.) from walls and objects.
If you are installing the projector in a sealed space, be sure to provide additional air
conditioning equipment and ventilation equipment. Insufcient ventilation will result in an
accumulation of heat and may activate the projector's protection circuit.
zAvoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).
■Dimensional relationship

Lens shift ranges
After moving the lens to the home position according to “Lens calibration” on page 7,
you can use the position of the projected image at that position (i.e., the standard
projection position) as a basis, and use the lens shift adjustment function on the projector
to adjust the position of the projected image within the respective lens shift ranges.
Perform lens shift adjustment within the ranges shown in the following illustrations.
Moving the lens outside of the adjustment ranges may alter the focus. This occurs due
to limitations in lens movement that are intended to protect the optical components.
The following illustrations depict lens shift ranges for oor installations of the projector.

Note
zThe home position of the projector a point of origin position for the lens shift (i.e., vertical and
horizontal positions of the lens) based on the results of lens calibration. It is not the optical
center position of the screen.

提示
z所列出的投影距离可能有 ±5 % 的误差。
此外， 当使用 [KEYSTONE] 时， 距离被校正为小于指定的屏幕尺寸。
z投射率基于投影期间使用的投影画面尺寸为 3.81 m (150”) 时的值。
Note
zA ±5 % error in listed projection distances may occur.
In addition, when [KEYSTONE] is used, distance is corrected to become smaller than the specied screen size.
zThe throw ratio is based on the value during projection with the projected image size of 3.81 m (150").
未列在上表中的安装尺寸， 请使用下面的公式进行计算。 请检查投影画面尺寸 SD (m)， 使用下面的公式确定投
影距离 (L)。
Setting-up dimensions which are not given in the above table can be calculated using the formulas below.
