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.

If 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 firmware.
If main version of the firmware is the version number shown below, update to the latest
firmware 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 firmware information on the
following website.
https://panasonic.net/cns/projector/pass/
zThe main version of the firmware version can be checked in the [STATUS] screen.

Before Use

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.
zDo not touch the electrical contacts of the projection lens with your fingers. 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 magnified 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 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 fluffy 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.
Peripheral focus adjustment function
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-D3LEW300 is equipped with a peripheral focus adjustment function to correct
the shift in focal balance between the center and peripheral areas of the screen.
For instructions on adjusting the peripheral focus, refer to “Projecting” in the operating
instructions for the projector.
Lens calibration
Perform lens calibration after attaching the lens.
For instructions on the lens calibration, refer to “Projecting” in the operating instructions
for the projector.

Note
zThe illustrations of projectors in this manual are for informational purposes only and do not
represent a specific projector model. Configurations may vary with the model.
Attention
zTo prevent obstruction of the intake and exhaust vents, install the projector with a
clearance from walls and objects. For details about the required distance from surrounding
walls and objects, refer to the operating instructions for your projector.
If you are installing the projector in a sealed space, be sure to provide additional air
conditioning equipment and ventilation equipment. Insufficient 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.).

Perform the lens position shift within the adjustment range.
Perform lens shift adjustment within the ranges shown in the following illustrations.
The focus may change when the lens position is shifted out of the adjustment range.
This is because the movement of the lens is restricted to protect the optical parts.
Projection position can be adjusted with the optical axis shift based on the home position
in the respective range.
