Read this rst! Always follow these precautions

WARNING:

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:

When moving or holding up the projector, be careful not to hold the projection

lens or the openings beside the projection lens.

zDoing so may damage the projector.

Do not touch or remove any parts except for the specied parts in this

Installation Instructions.

zDoing so may result in malfunctions, electrical shock, or accidents.

Supplied accessories and consumables:

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.

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 o󰀨 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 ngers. Dust and

dirt on the contacts may cause contact malfunctions.

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 cap 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 lens.

Do not use u󰀨y cloths containing oil, water or dust for cleaning. The material in the lens is

easily damaged, so do not apply excessive pressure when wiping it.

Attaching the Lens / Detaching the Lens

Before Use

(The product is

delivered with a lens

cap attached.)

ENGLISH-5

1) Remove the lens hole cover.

2) Align the red mark on the

projection lens with the red mark

on the projector, and insert the

projection lens as far as possible.

3) Slowly turn the lens clockwise

until it clicks into place.

Attention

zGently turn the projection lens

counterclockwise, and check that it does

not detach.

Turn the projection lens completely in

the counterclockwise direction while

pressing the lens release button to

detach the lens.

Attention

zAttach the supplied lens cap before

storing the lens.

Detaching the Lens

Adjusting the Focal Balance

The focal balance between the center and periphery of the projected image changes

depending on the size of the projected image.

The lens is equipped with a focus balance adjustment function for the screen periphery.

■Procedure for adjusting the focal balance

1) Focus the center of the screen by

operating the projector unit.

2) Turn the periphery focus ring by

hand as shown in the gure to

adjust the focus in the periphery

of the screen.

Note

zThe projected image sizes and scale shown on the periphery focus adjustment ring are an

approximate guide.

Making Adjustments

Periphery focus adjustment ring

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 gure 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.

Making Adjustments (continued)

■Procedure for correcting the focus

Attention

zTurn o󰀨 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.

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

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.

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.)

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 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.).
