Open the back cover.

While pushing on the back cover, slide it in the direction of the arrow.

Install the batteries.

Place the two batteries (AAA/R03-size) supplied in the remote control as illustrated below.

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 shortcircuiting. 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, 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 irritated.

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

and may not run that long. When the remote control starts failing to work properly, replace the batteries with new

ones.

Close the back cover.

Slide the back cover in the direction of the arrow until a click is heard.

Installing the Projector

Precautions for Installation

Do not install the projector in places where :

There is much water, humidity or dust. The projector may be subjected to oil smoke or cigarette smoke. The surface is soft, such as a carpet or cushion. The projector may be subjected to direct sunlight. Temperature is high or humidity is low. Allowable operation temperature range: + 5°C to + 35°C (41°F to 95°F) Allowable relative humidity range: Allowable storage temperature range:

When installing the projector, observe the followings:

Do not use the projector placed on its side.

Avoid using the projector placed on its side. This could cause a malfunction.

Use the projector within the installed angle.

Avoid using the projector inclined ±30° or more right-to-left or left-to-right. This could cause color variation or harm the lamp life.

Do not block the exhaust vents.

Do not use a cover which encloses the projector air-tight or blocks the exhaust vents. Allow sufficient space around the projector. When the projector is enclosed in a space of the following dimensions, use an air conditioner so the temperature inside becomes equal to the outside temperature.

Install the screen so the lower edge of the projected picture aligns with the extended center line of the projector’s lens.

That way, the lower edge of the picture projected on a 4 : 3 aspect ratio screen aligns with the extended center line of the

lens. Also, the screen must be at right angles with the extended center line of the lens (so that projection occurs at right angles with the screen). When installing the 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 picture is about 91.8% that of a 4 : 3 aspect ratio picture. This value is a guide and should be used as a reference. When projecting at the maximum projection distance (20 m/65.6 ft), we recommend that the projector be used with the zoom on the Tele (T).

If sunlight or lamp light strikes the projection screen directly, the picture becomes whitish and dim. Be sure to use a curtain, etc. to shield the light. Trapezoidal distortion may not be corrected. Adjust the projector within the range of angle adjustment (up/down adjustment angle: +7°; horizontal adjustment angle: ±1.5°) so that it is set up level.

The numeric values listed in the table of Relationship between Projection Distances and Screen Sizes on page 19 are

provided only as a guide or reference. The projection sizes may vary within manufacturing tolerances of the projection lens. When hanging the projector from the ceiling, use a dedicated hanging fixture.
