Preparation
Precautions with regard to safety
WARNING
If a problem occurs (such as no image or no sound) or if you notice
smoke or a strange smell coming from the projector, turn off the power
and disconnect the power cord from the wall outlet.
BDo not continue to use the projector in such cases, otherwise fire or
electric shocks could result.
BCheck that no more smoke is coming out, and then contact an Authorised
Service Center for repairs.
BDo 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.
BIf 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.
BIf 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, turn off the power and disconnect the
power cord from the wall outlet.
BContinued use of the projector in this condition may result in fire or electric
shocks.
BContact an Authorised Service Center for repairs.
Do not overload the wall outlet.
BIf 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.
BHigh voltages which can cause fire or electric shocks are present inside
the projector.
BFor any inspection, adjustment and repair work, please contact an
Authorised Service Center.
Clean the power cord plug regularly to prevent it from becoming
covered in dust.
BIf dust builds up on the power cord plug, the resulting humidity can
damage the insulation, which could result in fire. Pull the power cord out
from the wall outlet and wipe it with a dry cloth.
BIf not using the projector for an extended period of time, pull the power
cord plug out from the wall outlet.
