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.
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 Authorized
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, disconnect the power cord plug from
the wall outlet.
BContinued use of the projector in this condition may result in fire or electric
shocks.
BContact an Authorized 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 can cause fire or electric shocks.
BFor 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.
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 plug
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. 
						

							6-ENGLISH

plug.
BDo 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.
BIf the power cord lead is used while damaged, electric shocks, short-
circuits or fire may result.
BAsk an Authorized Service Center to carry out any repairs to the power
cord that might be necessary.
Do not handle the power cord plug with wet hands.
BFailure to observe this may result in electric shocks.
Insert the power cord plug securely into the wall outlet.
BIf the plug is not inserted correctly, electric shocks or overheating could
result.
BDo not use plugs which are damaged or wall outlets which are coming
loose from the wall.
Do not place the projector on top of surfaces which are unstable.
BIf the projector is placed on top of a surface which is sloped or unstable, it
may fall down or tip over, and injury or damage could result.

							ENGLISH-7
Preparation
Do not look into the lens while the projector is being used.
BStrong light is emitted from the projector’s lens. If you look directly into this
light, it can hurt and damage your eyes.
BBe especially careful not to let young children look into the lens. In
addition, turn off the power and disconnect the power cord plug when you
are away from the projector.
Keep the remote control unit out of the reach of children, and do not
look into the laser beam or point it towards other people.
BIf the laser beam which is emitted by the remote control unit transmitter is
pointed directly into the eyes, it may cause visual ability to be impaired.
Do not place your hands or other objects close to the air outlet port.
BHeated air comes out of the air outlet port. Do not place your hands or
face, or objects which cannot withstand heat close to this port, otherwise
burns or damage could result.
Replacement of the lamp unit should only be carried out by a qualified
technician.
BThe lamp unit has high internal pressure. If improperly handled, explosion
might result.
BThe lamp unit can easily become damaged if struck against hard objects
or dropped, and injury or malfunctions may result.
When replacing the lamp, allow it to cool for at least one hour before
handling it.
BThe lamp cover gets very hot, and contact with it can cause burns.
Before replacing the lamp, be sure to disconnect the power cord plug
from the wall outlet.
BElectric shocks or explosions can result if this is not done.
Caution
Do not cover the air inlet port or the air outlet port.
BDoing so may cause the projector to overheat, which can cause fire or
damage to the projector.
BDo not place the projector in narrow, badly ventilated places such as
closets or bookshelves.
Do not set up the projector in humid or dusty places or in places where
the projector may come into contact with smoke or steam.
BUsing the projector under such conditions may result in fire or electric shocks.
When disconnecting the power cord, hold the plug, not the lead.
BIf the power cord itself is pulled, the lead will become damaged, and fire,
short-circuits or serious electric shocks may result.
Always disconnect all cables before moving the projector.
BMoving the projector with cables still attached can damage the cables,
which could cause fire or electric shocks to occur. 
						

							8-ENGLISH
