Overview
• 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.
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 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.
On cleaning
• 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.
CRT burns
When a static picture of a VCR or a computer is displayed for more than
about an hour, a CRT burn may result. This means that an after-image
impression of the static picture remains on the screen even after the picture
has changed. If it is necessary to display the same static picture for more
than an hour, we recommend that you set the CONTR (contrast) control to
the lowest setting.
Also, when a picture of different size is displayed beyond a certain length
of time, an after-image impression of the frame of the smaller picture may
be burnt on the screen (such as displaying a 16:9 wide size picture on a 4:3
screen). To avoid this, we recommend that you use the same picture size
when possible. However, if it is necessary to use a different picture size,
set the CONTR (contrast) control and the BRT (brightness) control of the
smaller picture to the lowest setting possible. This will minimize the risk
of creating an after-image impression.
If the CRT burns, it must be replaced. In this case, refer to the warranty
provided with this unit. Consult your Sony dealer or Qualified Service
Personnel.
On repacking
Save the original shipping carton and packing material; they will come in
handy if you ever have to ship your unit. For maximum protection, repack
your unit as it was originally packed at the factory.
