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
rHazard distance (IEC/EN 62471-5:2015)
The distance from the projection lens surface, at which the emission reaches the Accessible
Emission Limit (AEL) of risk group 2, is known as the hazard distance (HD) or safety distance. The
area where the emission exceeds the Accessible Emission Limit of risk group 2 is called the hazard
zone (HZ).
Within the hazard zone, never look into the light projected from the projector. The eyes may be
damaged by direct irradiation even if you look at the light just for a moment. If you are outside the
hazard zone, it is considered to be safe in all circumstances except deliberately staring into the light
projected from the projector.

rRisk group
The combination of the projector and the projection lens is categorized as risk group 2 when the
hazard distance is 1 m (39-3/8") or less. It is categorized as risk group 3 when the hazard distance
exceeds 1 m (39-3/8"), and it will be for professional use instead of consumer use.
In the case of risk group 3, there is a possibility of damaging the eyes by direct irradiation when
looking into the projection light from inside the hazard zone even for a moment.
In the case of risk group 2, safe use without damaging the eyes is possible in all circumstances
except deliberately staring into the light projected from the projector.
The combination of projector and projection lens classified as risk group 3 with a hazard distance
greater than 1 m (39-3/8") is as follows.

Furthermore, each dimension to indicate the hazard area (Hz) for a combination with a projection
lens that has a hazard distance exceeding 1 m (39-3/8") is as follows.

*1 HD: Hazard distance
*2 The values of D1 to D4 will change in accordance with the lens shift amount. Each value in the table is the
maximum value.
Note
zThe values in the table are based on IEC/EN 62471-5:2015.
zThe projectors compatible with each projection lens may be added or changed without notice. For the latest
information, refer to the following website.
https://panasonic.net/cns/projector/
Attention
zIf the light projected from the projector directly enters the eyes while you are inside the hazard zone, the
retinas may be damaged. Do not enter the hazard zone during use. Alternatively, install the projector in a
location where the projected light will not directly enter the eyes.

Before Use

ENGLISH-7
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 electric contact points 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 turn the gear (ring) part of the projection lens barrel by hand. Doing so may damage
the motor.
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 may become damaged by hitting with a hard object or by wiping the front surface
of the lens with excessive force. Handle with care.
zUse a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use fl uffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
Attaching the Lens / Detaching the Lens
For details on attaching or removing the projection lens, refer to the operating
instructions for the projector.
Peripheral focus adjustment function
When you change the size of the projected image, the focal balance between the center
and peripheral areas of the screen may shift.
The ET-C1W300 / ET-C1W400 / ET-C1W500 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.

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.).

Projection relationships (continued)
■Dimensional relationship
For details on the projection distance (L), refer to “Projected image size and Projection
distance” and “Projection distance formulas” in the Appendix.
Note
zFor details on “Projected image size and Projection distance” for projector models other
than PT-REQ12 / PT-REQ10 / PT-REQ80, refer to “Setting up” in the operating instructions
of the projector.
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.
