Projection Distance and Screen Size

● The projection lens used in this projector is a long focal-distance zoom lens (1.9 x zoom lens f or 2.9:1 to 5.5:1) with

manual shift function.

● The range of projection distances that can be focused is approx. 14.83 ft (approx. 4.52 m) to approx. 98 ft (approx.

29.87 m) when the aspect ratio of the screen is 4:3. Set this projector within this range. Refer to “Relationship between Projection Distances and Projection Screen Sizes” (on pages 16 and 71).

● With this projector, the pr ojection screen can be shifted up and do wn in position within the range of appro x. 30% to

55%. The amount of shift shown in the illustration is 50% shifting. See page 17 for “Setting the Amount of Lens Shifting”.

*This list is extracted from “Relationship between Projection Distances and Projection Screen Size” on page 71. The projection

screen sizes and projection distances are only for a guide. Use them as reference when setting the projector.

Installing the Projector (Cont.)

CAUTIONS and NOTES

• When installing a screen, use a 4:3 aspect-ratio picture. (A 16:9 aspect-ratio picture is projected based on the width of the range in which a 4:3 aspect-ratio picture is projected.)

• The diagonal length of a 16:9 aspect-ratio screen is about 91.8% that of a 4:3 aspect-ratio screen. This value is only a guide (reference).

• If sunlight or lamp light strikes the projection screen directly, the picture tends to become whitish and dim. Be sure to use a curtain, etc. to shield the light.

• Trapezoidal distortion may not be corrected. Set the projector horizontally on a surface that is within the range of adjustable angles (up/down adjustment angle: +7° ; horizontal adjustment angle: ±1.5°).

• The values listed in table “Relationship between Projection Distances and Projection Screen Sizes” are provided only as a guide (reference). The projected screen size may vary depending on the manufacturing tolerance of the projection lens.

• When hanging from the ceiling, use a dedicated hanging fixture.

Setting the Amount of Lens Shifting

This projector features a lens shifting function which allows you to shift the projection screen up and down in position. Depending on installation conditions, you may need to use this function to make adjustments.

Notes

• The amount of shifting is within the range of approx. 30% to 55%. The factory setting is 30%.

• After finishing the lens shift setting (adjustment), tighten the SHIFT LOCK fixing bolt firmly so the lens will not move.

Loosen the SHIFT LOCK fixing

bolt.

Use the hex wrench supplied.

Rotate the LENS SHIFT knob to ad-

just the position (shift amount) of the projection screen.

Rotate it to the right: The lens shifts upward. Rotate it to the left: The lens shifts downward.

Tighten the SHIFT LOCK fixing

bolt firmly.

Use the hex wrench supplied.

Setting the Position Selecting Screw for Ceiling Mounting

When using the projector in an upside-down, ceiling-mounted position (inverted top-to-bottom and right-to-left), the “position selecting screw for ceiling mounting” must be turned to switch to ceiling mounting. This will correct variance in color images (shading), which otherwise would occur in ceiling mounting. To revert to normal desktop setting, turn the “position selecting screw for ceiling mounting” back to the initial position (factoryshipped).

[When using the projector in an upside-down, ceiling mounting position (inverted top-to-bottom and right-to-left)]

■ Turn the “position selecting screw for ceiling mounting” counterclockwise fully (until it is turning idly).

[To again use the projector in a normal desktop setting]

■ Turn the “position selecting screw for ceiling mounting” clockwise fully (until it tightens firmly).

For normal desktop mounting:

Turn clockwise.

For upside-down, ceiling-mounting:

Turn counterclockwise.

CAUTIONS

• To ceiling-mount and adjust the projector, special expertise and technique are necessary. Be sure to ask your dealer or a specialist to perform this work.

• To turn the “position selecting screw for ceiling mounting”, use a Phillips screwdriver with a 30-mm or longer shank.

Memo

When the OPERATE button is pressed but the power is not supplied:

•If the filter or lamp replacement opening cover is displaced, the power is not supplied. Check them for correct installation.

•You must press the OPERATE button for one second or more.

CAUTIONS and NOTES

Do not turn off the MAIN POWER switch suddenly while the projector is being used or immediately after it has been used. This could cause a malfunction.

•Since the projector uses a high-intensity lamp and is heated to high temperature, cooling fans are operating even during

projection. So, after use, the cooling fans continue to run from when the OPERATE button is pressed until the light-source lamp is cooled down. During cooling, the STAND BY indicator blinks to alert the cooling fans are running. During this time, do not turn off the main power switch. After the cooling of the light-source lamp is finished (the fans stop) and the STAND BY indicator comes on, then turn off the main power switch.

•If you press the OPERATE button immediately after the light-source lamp lights, it takes about 40 seconds for the lamp to go

off. To turn the lamp on again, wait 10 seconds or more before pressing the OPERATE button.

ENGLISH

When the TEMP indicator lights, the power turns off automatically.

•While the light-source lamp is on, if an abnormal temperature rise is detected, the TEMP indicator comes on, the power is

automatically cut off, and the projector’s EMERGENCY indicator blinks (goes into an emergency mode).

When the EMERGENCY indicator blinks, turn off the main power switch after the fans have stopped running.

•If the following abnormality occur to the projector, it goes into an emergency mode (the EMERGENCY indicator blinks).

When the projector goes into an emergency mode, it stops projecting automatically and runs the fans for about 20 seconds. – When the filter is dislodged. – When the filter is clogged. – When the light-source lamp suddenly goes off. – When the fans stop running. – When the temperature inside rises abnormally high. – When the AC power supply is suddenly cut or interrupted.

•When the projector goes into an emergency mode:

After the fans have stopped, turn off the MAIN POWER switch and pull out the power cord. After that, re-insert the power cord and try to operate the projector. If it goes into emergency again, after the fans have stopped, turn off the main power switch, pull out the power cord, and consult your authorized dealer or service center for repair.
