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.

Do not allow children to reach the spacer.

zThe spacers can cause personal injury if swallowed.

zIf the spacers are swallowed, seek medical advice immediately.

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.

Note

zThis manual omits the alphabets at the end of projector model numbers.

zModels other than the above may also be supported. Refer to the operating instructions of

the projector you are using.

■Supplied Accessories

Make sure that the following has been provided.

Part name Appearance

1 each for front and rear

Spacer

(T0SAS0001--) (Colors: black, cream, clear) 4 each

zThe product is delivered with a

lens cap attached.

zThe shape and size of the lens

caps are different for each product.

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.

Attaching / removing the projection lens (continued)

Making Adjustments

Correcting the Focus

When the projection lens is attached to the projector and images are being projected

onto the screen, the peripheral focus may be out of focus in some localized areas.

In such cases, use the supplied spacers to correct the focus of these areas, and perform

adjustments so that the entire image is even.

■Relationship between lens orientation and screen focus

If the projection lens is tilted with respect to the plane of the screen, uneven focus will

result. For example, when the front side of the lens (screen side) is tilted downward as

shown in the figure below (direction of the dotted arrow), the upper part of the screen

will be tilted backward and the lower part of the screen will be tilted forward.

Screen surface versus focal point

■Procedure for correcting the focus

Attention

zTurn off the projector before removing the projection lens.

Note

zFocus correction requires some technical skill. Be sure to have a person with knowledge of

projectors or a service technician to perform adjustments.

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.

Spacers

1) Install the projector in the installation location, and turn it on to project an image.

2) Move the lens to its home position.

3) Operate the projector to shift the focus of the entire projected image toward

the front of the screen.

4) Operate the projector to shift the focus toward the screen a little bit at a time until

one of the areas A to D in Fig. 1 just comes into focus on the screen, and then stop.

zIn this state, the “just focus points” of the unfocused areas are positioned just in front of

the screen. The distance between this position and the screen is the correction distance.

5) Insert the spacers between the body of the projector and the lens mounter, as

shown in Fig. 2.

zRemove the lens mounter from the projector, and insert the spacers in the positions

that correspond to the unfocused areas.

zThe “just focus points” of the areas for which you inserted spacers will be corrected

toward the rear of the screen.

zMake sure the adhesive surfaces of the spacers face the lens mounter when inserting them.

zThe correction distance is determined by the thickness and quantity of spacers

inserted. Insert spacers according to the correction distance.

(The unit for correction distances derived from the formulas in the following table is millimeters.)

Spacer Color Thickness Correction distance

during projected image size SD (m)

Clear 0.1 mm SD × SD × 51.5

Black

0.2 mm SD × SD × 103

Cream

0.3 mm SD × SD × 154.5

Correction distance guide: When the projected image size is 1.52 m (60 in.), the cor-

rected distance when one 0.1 mm thick spacer is inserted is 120 mm.

Attention

zInstalling the lens mounter, be careful not to put wiring between the lens mounter and the

projector unit.

Projection relationships (continued)

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.).

■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-MZ770 / PT-MW730 / PT-MZ670 / PT-MW630 / PT-MZ570 / PT-MW530 /

PT-EZ770 / PT-EW730 / PT-EX800, 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.

Moving the lens outside of the adjustment ranges may alter the focus. 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.
