or staining or damaging the surrounding.
Beware of the following:
• Do not mix new and old batteries.
• Do not mix different types of batteries as they differ in
characteristics.
• Place batteries so they match the polarities indicated:
(+) to (+) and (–) to (–).
• Be sure to put the minus (–) end in first to avoid short-
circuiting.
• Use only designated batteries.
• Remove the batteries if not used for a prolonged period
of time.
• When the batteries are exhausted, replace them
immediately. Otherwise, liquidcould leak, or malfunction
could occur due to leaked liquids. If the leaked liquid
contacts the skin, wipe it off with a cloth, otherwise the
skin could become rough.
• Do not put batteries into fire or try to recharge them.
• Batteries run for six months to one year in normal use.
But the batteries supplied are for confirming operation
andmay not run that long.Whentheremote control starts
failing to work properly, replace the batteries with new
ones.

Projection Distance and Screen Size
■The projection lens used in this projector is a 1.5 : 1, short focal-distance lens (with a manual shift function).
■The range of projection distances that can be focused is 60” screen (approx. 1.76 m) to 150” screen (approx. 4.499
m) when the aspect ratio of the screen is 4:3.
■With this projector, the projection screen can be shifted up and down in position within the range of approx. 30% to
55%. The amount of shift shown in the illustration is 50% shifting which corresponds to the factory setting. See
page 17 for “Setting the Amount of Lens Shifting.”
Screen
When the amount of shift is
selected to be 50% (factory
setting), set the screen so that its
bottom edge is the same height
as the center line of the lens.

Relationship between Projection Distances and Projection Screen Sizes
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 pro-
jected.)
•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 adjust-
able angles (up/down adjustment angle: +7° ; horizontal adjustment angle: ±1.5°).
•The values listed in table “Relationship between Projection Distances and 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 the from the ceiling, use a dedicated hanging fixture.
Setting the Amount of Lens Shifting
Thisprojectorfeatures a lens shifting function which allows you to shiftthe projection screen upand down in position.Depending
on installation conditions (such as dual stacking), 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 50%.
•After finishing the lens shift setting (adjustment), tighten the SHIFT LOCK fixing bolt firmly so the lens will not move.
1Loosen the SHIFT LOCK fixing
bolt.
Use the hex wrench supplied.
2Rotate the LENS SHIFT knob to
adjust 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.
3Tighten 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 desltop setting, turn the “position selecting screw for ceiling mounting” back to the initial position (factory-
shipped).
[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).
Position selecting screw for ceiling mounting
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.
• Toturnthe“position selecting screw forceilingmounting”, usea Phillips
screwdriver with a 30-mm or longer shank.
