(GB) Overview
• To avoid moisture condensation, do not install the unit in a location
where the temperature may rise rapidly.
• Fans are installed inside the projector to prevent internal heat build-up.
The fans produce a humming noise when the power is switched on, which
is normal. Should the noise sound abnormal, please consult qualified
Sony personnel.
• 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 projector 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.
To turn on the projector after the projector has been turned off due to a
brief loss of power, press the ON key on the remote commander, or turn
off the MAIN POWER switch so that the STANDBY indicator turns off
and then turn on the MAIN POWER switch.
• To keep the cabinet looking new, periodically clean it with a soft cloth.
Stubborn stains may be removed with a cloth lightly dampened with a
mild detergent solution. Never use strong solvents, such as thinner,
benzene, or abrasive cleansers, since these will damage the cabinet.
• 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.
