Precautions with regard to safety
WARNING
If you notice smoke, strange smells or noise coming from the
projector, disconnect the power cord plug from the wall outlet.
• Do not continue to use the projector in such cases, otherwise fire or
electric shocks could result.
• Check that no more smoke is coming out, and then contact an Authorized
Service Center for repairs.
• Do not attempt to repair the projector yourself, as this can be dangerous.
Do
not install this projector in a place which is not strong enough to
take the full weight of the projector.
• If the installation location is not strong enough, it may fall down or tip over,
and severe injury or damage could result.
Installation
work (such as ceiling suspension) should only be carried
out by a qualified technician.
• If installation is not carried out correctly, there is the danger that injury or
electric shocks may occur.
If foreign objects or water get inside the projector, or if the projector is
dropped or the cabinet is broken, disconnect the power cord plug from
the wall outlet.
• Continued use of the projector in this condition may result in fire or electric
shocks.
• Contact an Authorized Service Center for repairs.
Do
not overload the wall outlet.
• If the power supply is overloaded (for example, by using too many
adapters), overheating may occur and fire may result.
Do
not remove the cover or modify it in any way.
• High voltages can cause fire or electric shocks.
• For any inspection, adjustment and repair work, please contact an
Authorized Service Center.
Clean
the power cord plug regularly to prevent it from becoming
covered in dust.
• If dust builds up on the power cord plug, the resulting humidity can
damage the insulation, which could result in fire. Pull the power cord plug
out from the wall outlet and wipe it with a dry cloth.
• If not using the projector for an extended period of time, pull the power
cord plug out from the wall outlet.
Do
not do anything that might damage the power cord or the power
cord plug.
• Do not damage the power cord, make any modifications to it, place it near
any hot objects, bend it excessively, twist it, pull it, place heavy objects on
top of it or wrap it into a bundle.

10-ENGLISH

Notes on use
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off any lights near the
screen to prevent outside light or light from indoor lamps from shining onto
the screen.
Do
not touch the surfaces of the lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints or anything else, this
will be magnified and projected onto the screen.
Screen
Do not apply any volatile substances which may cause discoloration to the
screen, and do not let it become dirty or damaged.
Lamp
The lamp may need to be replaced earlier due to variables such as individual
lamp characteristics, usage conditions and the installation environment,
especially when the projector is subjected to continuous use for more than
10 hours or the power is frequently turned on and off.
Liquid crystal panel
The liquid crystal panel of the projector is built with very high precision
technology to provide fine picture details. Occasionally, a few non-active
pixels may appear on the screen as fixed points of blue, green or red.
Please note that this does not affect the performance of your LCD.
