WARNING:
 
r POWER
The wall outlet or the circuit breaker shall be installed near the equip\
ment and shall be easily acces
-
sible when problems occur. If the following problems occur, cut off the power supply immediately.
Continued use of the projector in these conditions will result in fire or electric shock.  
f If foreign objects or water get inside the projector, cut off the power supply.
 
f If the projector is dropped or the cabinet is broken, cut off the power supply.
 
f If you notice smoke, strange smells or noise coming from the projector
, cut off the power supply.
Please contact an Authorized Service Center for repairs, and do not attempt to repair the projector yourself.
During a thunderstorm, do not touch the projector or the cable.
Electric shocks can result.
Do not do anything that might damage the power cord or the power plug.
If the power cord is used while damaged, electric shocks, short-circuits or fire will result.  
f Do not damage the power cord, make any modifications to it, place it near any hot objects, bend it exces
-
sively, twist it, pull it, place heavy objects on top of it or wrap it into a bundle.
Ask an Authorized Service Center to carry out any repairs to the power cord that might be necessary.
Completely insert the power plug into the wall outlet and the power conn\
ector into the projector termi -
nal.
If the plug is not inserted correctly, electric shocks or overheating will result.  
f Do not use plugs which are damaged or wall outlets which are coming loos\
e from the wall.
Do not use anything other than the provided power cord.
Failure to observe this will result in electric shocks or fire. Please note that if you do not use the provided power 
cord to ground the device on the side of the outlet, this may result in electric shocks.
Clean the power plug regularly to prevent it from becoming covered in du\
st.
Failure to observe this will cause a fire.  
f If dust builds up on the power plug, the resulting humidity can damage the insulation.
 
f If not using the projector for an extended period of time, pull the power plug out from the wall outlet.
Pull the power plug out from the wall outlet and wipe it with a dry clot\
h regularly.
Do not handle the power plug and power connector with wet hands.
Failure to observe this will result in electric shocks.
Do not overload the wall outlet.
If the power supply is overloaded (ex., by using too many adapters), overheating may occur and fire will result.
 
r ON USE/INSTALLATION
Do not place the projector on soft materials such as carpets or sponge m\
ats.
Doing so will cause the projector to overheat, which can cause burns, fire or damage to the projector
.
Do not set up the projector in humid or dusty places or in places where \
the projector may come into 
contact with oily smoke or steam.
Using the projector under such conditions will result in fire, electric shocks or deterioration of components. 
Deterioration of components (such as ceiling mount brackets) may cause the projector which is mounted on the 
ceiling to fall down.
Do not install this projector in a place which is not strong enough to t\
ake the full weight of the projector 
or on top of a surface which is sloped or unstable.
Failure to observe this will cause projector to fall down or tip over the projector , and severe injury or damage 
could result.

WARNING:
Do not cover the air intake/exhaust ports.
Doing so will cause the projector to overheat, which can cause fire or damage to the projector.
 
f Do not place the projector in narrow, badly ventilated places.
 
f Do not place the projector on cloth or papers, as these materials could be drawn into the air intake port.
 
f Provide at least 1 m (40") of space between any walls or objects and the exhaust port, and at least 50 cm (20") 
of space between any walls or objects and the intake port.
Do not place your hands or other objects close to the air exhaust port.
Doing so will cause burns or damage your hands or other objects.  
f Heated air comes out of the air exhaust port. Do not place your hands or face, or objects which cannot with
-
stand heat close to this port.
Do not look at or place your skin into the light emitted from the lens w\
hile the projector is being used.
Doing so can cause burns or loss of sight.  
f Strong light is emitted from the projector’s lens. Do not look at or place your hands directly into this light.
 
f Be especially careful not to let young children look into the lens. In addition, turn of
f the power and switch 
off the main power when you are away from the projector.
Never attempt to remodel or disassemble the projector.

tor.  
f Do not place containers of liquid or metal objects near the projector
.
 
f If liquid enters inside of the projector, consult your dealer.
 
f Particular attention must be paid to children.
Use the ceiling mount bracket specified by Panasonic.
Using the ceiling mount bracket other than the specified one will result in falling accidents.  
f Attach the supplied safety cable to the ceiling mount bracket to prevent the projector from falling down.
Installation work (such as ceiling mount bracket) should only be carried out by a qualified technician.
If installation is not carried out and secured correctly, it can cause injury or accidents, such as electric shocks.  
f Be sure to use the wire provided with the ceiling mount bracket as an extra safety measure to prevent the
