Installing Batteries
Install batteries in the remote control. If the remote control has started to work erratically, replace the batteries.
1Open the back cover.
While pushing on the back cover, slide it in the direction
of the arrow.
2Install the batteries.
Place the two batteries (AAA/R03-size) supplied in the
remote control as illustrated below.
3Close the back cover.
Slide the back cover in the direction of the arrow until a
click is heard.
Precautions for using batteries
If batteries are used incorrectly, they may crack or
leak liquid. This could cause a fire, burn, malfunction,
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, liquid could leak, ormalfunction
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
andmaynotrunthatlong. When the remote controlstarts
failing to work properly, replace the batteries with new
ones.

Installing the Projector (Cont.)
Setting the Amount of Lens Shifting
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.
• Trapezoidaldistortionmay not be corrected. Set the projector horizontallyonasurface 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 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 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).
