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.

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 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 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-EMW200 / ET-EMW300 / ET-EMW400 / ET-EMW500 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 lens calibration, refer to “Projecting” in the operating instructions for
the projector.

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 blocking of the intake and exhaust vents, maintain clearances from walls and objects
of at least 1 000 mm (3'3") for the exhaust vent and at least 500 mm (1'8") for the intake vent.
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-MZ16K / PT-MZ13K / PT-MZ10K, refer to “Setting up” in the operating instructions
of the projector.
Lens shift ranges
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.
