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.
WARNING (North America)
A projector would become Class IIIb laser product when this lens is used under the
condition that throw ratio is greater than 3.0, and if used without lens hood. If you use
under this condition, you must receive variance approval letter from FDA before usage.
Class IIIb levels of laser radiation are considered to be an acute hazard to the skin and
eyes from direct radiation.
Note
zThe lens hood needs to be mounted to the projector when this lens is used under the
condition that throw ratio is greater than 3.0 in the North America region. Always ask a
qualied technician or your dealer to mount the lens hood.
For the assembly and attachment, refer to the separate document “Mounting the lens hood”.
The components and document of the lens hood may not be supplied depending on the
country or region where you purchased the product.

■Supported projectors
PT-RQ32K / PT-RZ31K / PT-RS30K / PT-RQ22K / PT-RZ21K / PT-RS20K
Note
zSome of the alphabet letters at the end of projector model numbers may be omitted in this
manual.
zModels other than the above may also be supported. Refer to the operating instructions for
your projector or the Panasonic website (https://panasonic.net/cns/projector/).
zIf the projector you are using is PT-RQ32K / PT-RZ31K / PT-RS30K / PT-RZ21K /
PT-RS20K, you may not be able to use the projection lens depending on main version of
the rmware. If main version of the rmware is the version number shown below, update to
the latest rmware before use.
- PT-RQ32K / PT-RZ31K / PT-RS30K: Earlier than 3.00
- PT-RZ21K / PT-RS20K: Earlier than 2.00
For details on the update procedure, refer to the latest rmware information on the
Panasonic website (https://panasonic.net/cns/projector/pass/).
zThe main version of the rmware can be checked in the [STATUS] screen.

Attaching and Detaching the Lens
For details on attaching and detaching the projection lens, refer to the operating instructions
of the projector.
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.

Peripheral focus adjustment function (ET-D3LEW10)
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-D3LEW10 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-RZ21K 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.).

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.
