Precautions - Sony CPJ-A300 Operating Instructions Manual

Precautions

Installation
• Place the projector so that the lens is
perpendicular to the projected
plane. Otherwise the picture will
become distorted and may be out of
focus.
• You will be able to see the picture
more clearly in a darker place.
• The picture brightness depends on
the quality of the surface of the
projected plane. Select a flat and
white surface.
• The picture gets darker as the
distance to the projected plane
increases.
• Allow adequate air circulation to
prevent internal heat buildup. Do
not place the projector on surfaces
near materials (curtains, draperies)
that may block the ventilation holes.
Leave space of more than 12 inches
(30 cm) between the wall and the
projector.
• Do not install the appliance in a
confined space, such as a book case
or build-in cabinet.
• Do not place the projector 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 place the projector in a location
where the temperature may rise
rapidly.
Operation
• Do not point the lens toward the
sun.
• Do not look into the lens during
projection.
• Should any liquid or solid object fall
into the cabinet, unplug the
projector and have it checked by
qualified personnel before operating
it further.
• Unplug the projector from the wall
outlet when you are not using the
projector.
• To disconnect the AC power cord,
pull it out by the plug. Never pull
the AC power cord itself.
• Do not use the projector near an AM
radio or tuner.
Cleaning the projector
• Be sure to turn off the power and
disconnect the AC power cord from
a wall outlet before cleaning.
• Clean the projector with a soft, dry
cloth. If the projector is very dirty,
wipe it off with a soft cloth lightly
moistened with a mild detergent
solution, and then wipe with a soft
dry cloth. Do not apply any type of
solvent as it may damage the finish.
• Wipe the mirror for the IR receiver
carefully.
Cleaning the lens
• Clean the surface of the lens with a
blower brush. Do not rub with a
cloth. Lens cleaning tissue papers
are recommended.

the leaflet "IMPORTANT
SAFEGUARDS" included with this
manual in the vinyl bag.
