Precautions

Safety

• Check that the operating voltage of your unit is identical with the voltage of your local power supply. If voltage adaptation is required, consult with qualified Sony personnel.

• Should any liquid or solid object fall into the cabinet, unplug the unit and have it checked by qualified personnel before operating it further.

• Unplug the unit from the wall outlet if it is not to be used for several days.

• To disconnect the cord, pull it out by the plug. Never pull the cord itself.

• The wall outlet should be near the unit and easily accessible.

• The unit is not disconnected to the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

• Do not look into the lens while the lamp is on.

• Do not place your hand or objects near the ventilation holes. The air coming out is hot.

• Be careful not to get your fingers caught in the adjuster.

• Do not spread a cloth or paper under the unit.

Illumination

• To obtain the best picture, the front of the screen should not be exposed to direct lighting or sunlight.

• Ceiling-mounted spot lighting is recommended. Use a cover over fluorescent lamps to avoid lowering the contrast ratio.

• Cover any windows that face the screen with opaque draperies.

• It is desirable to install the unit in a room where floor and walls are not of lightreflecting material. If the floor and walls are of reflecting material, it is recommended that the carpet and wall paper be changed to a dark color.

Preventing internal heat build-up

The unit is equipped with ventilation holes (intake) and ventilation holes (exhaust). Do not block or place anything near these holes, or internal heat build-up may occur, causing picture degradation or damage to the projector.

Cleaning

Before cleaning

Be sure to disconnect the AC power cord from the AC outlet.

Cleaning the air filter

• Clean the air filter whenever you replace the lamp.

• Refer to the “Cleaning the Air Filter” on page 48 for the air filter cleaning.

Cleaning the lens

The lens surface is especially treated to reduce reflection of light. As incorrect maintenance may impair the performance of the projector, take care with respect to the following:

• Avoid touching the lens. To remove dust on the lens, use a soft dry cloth. Do not use a damp cloth, detergent solution, or thinner.

• Wipe the lens gently with a soft cloth such as a cleaning cloth or glass cleaning cloth.

• Stubborn stains may be removed with a soft cloth such as a cleaning cloth or glass cleaning cloth lightly dampened with water.

• Never use solvent such as alcohol, benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning cloth, as they will damage the lens surface.

Cleaning the cabinet

• Clean the cabinet gently with a soft dry cloth. Stubborn stains may be removed with a cloth lightly dampened with mild detergent solution, followed by wiping with a soft dry cloth.

• Use of alcohol, benzene, thinner or insecticide may damage the finish of the cabinet or remove the indications on the cabinet. Do not use these chemicals.

Precautions

• If you rub on the cabinet with a stained cloth, the cabinet may be scratched.

• If the cabinet is in contact with a rubber or vinyl resin product for a long period of time, the finish of the cabinet may deteriorate or the coating may come off.

LCD data projector

This LCD data projector is manufactured using high-precision technology. You may, however, see tiny black points and/or bright points (red, blue, or green) that appear continuously on the LCD data projector. This is a normal result of the manufacturing process and does not indicate a malfunction. When the images are projected onto the screens from multiple LCD data projectors, they may generate color distinctions because each projector has its own color balance even if the projectors are the same models.

Notes on Installation and Usage

Unsuitable Installation

Do not install the projector in the following situations. Installation is these situations

or locations may cause a malfunction or damage to the unit.

Poorly ventilated locations

• Allow adequate air circulation to prevent internal heat build-up. Do not place the unit on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies) that may block the ventilation holes. When internal heat builds up due to blockage of ventilation holes, the temperature sensor will function, and the power will be turned off automatically.

• Leave space of more than 30 cm (11 inches) around the unit.

• Be careful not to allow the ventilation holes to inhale tiny objects such as pieces of paper or clumps of dust.

Notes on Installation and Usage

Hot and humid

Very dusty, extremely smoky locations

• Avoid installing the unit in a location where the temperature or humidity is very high, or the temperature is very low.

• To avoid moisture condensation, do not install the unit in a location where the temperature may rise rapidly.

Locations subject to direct cool or warm air from an air-conditioner

Installing the projector in such a location may cause a malfunction of the unit due to moisture condensation or a rise in temperature.

Near a heat or smoke sensor

Malfunction of the sensor may occur.

Avoid installing the unit in a very dusty or extremely smoky environment. Otherwise, the air filter will become obstructed, and this may cause a malfunction of the unit or damage it. Dust preventing the air passing through the filter may cause a rise in the internal temperature of the unit. Clean the air filter whenever you replace the lamp.

Unsuitable Conditions

Do not use the projector under the following conditions.

Do not stand the unit upright on one side

Avoid using the unit standing upright on its side. It may cause malfunction.

Do not tilt the unit to the right or left

Notes on Installation and Usage

Avoid tilting the unit to an angle of 15°, and avoid installing the unit in any way other than placing it on a level surface or suspending from the ceiling. Such an installation may cause color shading or shorten the lamp life excessively.

Do not block the ventilation holes

Usage at High Altitude

When using the projector at an altitude of 1,500 m or higher, turn on “High Altitude Mode” in the INSTALL SETTING menu. Failing to set this mode when using the projector at high altitudes could have adverse effects, such as reducing the reliability of certain components.

Avoid using a thick-piled carpet or anything that covers the ventilation holes (exhaust/ intake); otherwise, internal heat may build up.

Do not place a blocking object just in front of the lens

Do not place any object just in front of the lens that may block the light during projection. Heat from the light may damage the object. Use the PIC MUTING key to cut off the picture.

Do not use the Security bar for transporting or installation

Notes on Use

Note on carrying the projector

The unit is manufactured using highprecision technology. When transporting the unit, do not drop the unit or subject it to shock, as this may cause damage.

Note on the screen

When using a screen with an uneven surface, a striped pattern may rarely appear on the screen depending on the distance between the screen and the projector or the zooming magnification settings used. This is not a malfunction of the projector.

Use the Security bar at the rear of the projector for a purpose of preventing theft, by attaching a commercially available theft prevention cable for example. If you lift the projector by holding the Security bar, or hang the projector by using this bar, it may cause the projector to fall or be damaged.
