Precautions

On 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 Sony 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 from 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 catch your fingers by the adjuster when you adjust the height of the unit. Do not push hard on the top of the unit with the adjuster out.

•Be sure to grasp both sides of the unit with both hands when carrying the unit.

On 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 light- reflecting 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.

On preventing internal heat buildup

•After you turn off the power with the I / 1 key on the control panel or on the Remote Commander, do not disconnect the unit from the wall outlet while the cooling fan is still running.

Caution

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

On cleaningBefore cleaning

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

On 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.

On 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.

On cleaning the cabinet

•Clean the cabinet gently with a soft dry cloth. Stubborn stains may be removed
