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 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.

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 42 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.
