Sony Super Bright VPH-1001Q Operating Instructions Manual page 5

Precautions
On safety
e Check that the operating voltage of your unit is identical
with the voltage of your local power supply. If voltage
adaptation is required, consult your Sony dealer or
qualified personnel.
e 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 or set the MAIN
POWER switch to OFF 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 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.
On installation
e 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.
Be aware that room heat rises to the ceiling; check that
temperature near the installation location is not
excessive.
Do not install the unit in a location near heat sources
such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust or humidity, mechanical
vibration or shock.
To avoid moisture condensation, do not install the unit in
a location where the temperature may rise rapidly.
When the projector is mounted on the ceiling, the Sony
PSS-722/PSS-10 projector suspension support must be
used for installation.
On illumination
¢ To obtain the best picture, the front of the screen should
not be exposed directly to illumination or sunlight.
e Ceiling mounted spot lighting is recommended. Use a
cover over fluorescent lamps to avoid lowering 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 brand-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 or 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.
On repacking
e 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.
On CRT burns
When a static picture of a video or computer signal is
displayed for more than approximately one hour, a CRT
burn may result. This means that an after-image
impression of the static picture remains on the screen even
after the signal is changed. If it is necessary to display the
same static picture for more than approximately one hour,
we recommend that you set the CONTR (contrast) control
to the lowest setting possible.
Also, when a picture of different size is displayed beyond a
certain length of time, an after-image impression of the
picture frame of smaller picture may be burnt on the screen
(such as displaying a 16:9 picure 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 making an
after-image impression.
Should a CRT burn occur, the CRT must be replaced. In
this event, the cost of replacing the CRT is not covered
under the warranty provided with this unit. Consult your
Sony dealer or qualified personnel.
On spotting on the lens
When you look into the lens from the front side of the
projector, small bubbles, or small black spots that look like
dust, may be seen on the lens. These spots do not affect the
image you project on the screen.
