■■
■Safety Precautions
Read and observe the following safety precautions to ensure safe use of the equipment.
Warning
●If any of the following abnormalities occur, switch off the power sup-
ply immediately, remove the plug from the power socket and contact
your dealer or nearest address provided at page 96.
· The emission of smoke, strange odors or strange noises.
· Faults, such as images not being able to be projected or no sound being
emitted.
· When water or foreign objects have entered the inside of the unit.
· When the unit has been dropped or the case damaged.
Continuation of operations under these conditions may result in the out-
break of fire or electric shocks.
Repairs should never be attempted by the user.
●The cabinet to the unit should never be opened by anyone other than
our service personnel.
The inside of the projector contains many high-voltage parts that may
result in the outbreak of fire, electric shocks or other incidents.
●Never use an electrical voltage other than that displayed.
The use of a voltage other than that specified may result in the outbreak of
fire or electric shocks.
●Verify the specifications of the Power Cord.
The Power Cord supplied with the projector conforms to the electrical
specifications of the country of purchase. If the projector is to be used in
any other location, check the electrical voltage and shape of sockets in the
relevant country beforehand and purchase a cable that conforms to that
country’s specifications.
●Never use damaged Power Cord.
Failure to observe this may result in the outbreak of fire or electric shocks.
Also ensure that the following points are strictly observed.
· Never make any modifications to the Power Cord.
· Never place anything heavy on the Power Cord.
· Never bend, twist or pull the cable.
· Ensure that the cable is not installed near heaters.
Contact your dealer or nearest address provided at page 96 if the power
cord becomes damaged.

Safety Precautions - 9
●Never look into the lens when the power is switched on.
An extremely strong light is emitted that may cause sight defects. Special
attention must be paid by households with children.
●Take care when handling power plugs and power connectors.
Failure to observe these instructions may result in the outbreak of fire or
electric shocks.
Observe the following precautions when handling power plugs and power
connectors.
· Never connect too many appliances to a single socket.
· Never use plugs or connectors to which dust, dirt or other foreign objects
have adhered.
· Ensure that the plugs and connectors are firmly inserted as far as they
will go.
· Do not atempt to plug in plugs or connectors with wet hands.
· Do not pull the Power Cord when disconnecting plugs and connectors.
Always ensure that the actual plug or connector is firmly gripped.
●The projector includes many glass parts, such as the lens and lamps.
If any of these parts should break, handle them with extreme care to avoid
injury and then contact your dealer or nearest address provided at page 96
and request repairs.
●Never place vases or containers that contain liquid on top of the pro-
jector.
If the water is spilt and enters the outer case, it may result in the outbreak
of fire or electric shocks.
●Never insert or drop metal or inflammable objects, or any other for-
eign objects into the suction inlets and ventilation outlets on the pro-
jector.
Failure to observe this may result in the outbreak of fire or electric shocks.
●Never place the projector or the battery-operated remote control in
locations with excessive temperatures, such as in vehicles with
closed windows, in areas subject to direct sunlight, or near the fan
outlets of air-conditioners and heaters.
Failure to observe this may result in heat-distortion that would have an
adverse affect on the contents of the projector, and may result in the out-
break of fire or electric shocks.
●Do not block or look inside the main unit's ventilation outlet.
Failure to observe this may result in injury through glass shreds if the lamp is broken.
Warning

10 - Safety Precautions
Caution
●Never stand on the projector or place any heavy objects on it.
Failure to observe this may result in it dropping over, becoming damaged,
or causing injury.
●Never place the projector on unstable surfaces, such as wobbly
tables or slanted surfaces.
Failure to observe this may result in it dropping over, becoming damaged,
or causing injury.
●Do not place or store the projector within the reach of children’s
hands.
Failure to observe this may result in it dropping over, becoming damaged,
or causing injury.
●Do not place the projector in humid or dusty locations, or in loca-
tions where it would be subject to oil steam or water steam, such as
kitchens or near humidifiers.
Failure to observe this may result in the outbreak of fire or electric shocks.
●Never block the projector’s suction inlets or ventilation outlets. Fail-
ure to observe this may result in the build up of high temperatures
inside the projector, leading to the outbreak of fire. Do not place the
projector in the following locations.
·In narrow, badly ventilated areas, such as in cupboards or in bookcases.
·On top of carpets, matresses or blankets.
·Never cover the projectors with table cloth or other material.
Also, if placing by a wall, ensure that at least 20cm of space has been pro-
vided between the projector and the wall.
●Always ensure that the plug has been disconnented from the power
socket when it is not to be used.
Failure to observe this may result in the outbreak of fire.
●Always ensure that the power has been switched off, the plug has
been disconnected from the power socket, and all other cables have
been disconnected when moving the projector.
Failure to observe this may result in the outbreak of fire or electric shocks.

Safety Precautions - 11
●Never attempt to remove the lamp immediately after the projector has
been used. Wait for the projector to cool down sufficiently by leaving
it for at least sixty minutes after the power supply has been switched
off.
Failure to observe this may result in burns or other injuries.
●Misuse of the batteries may result in damage to the batteries and
subsequent leakages, leading to the outbreak of fire, injury and prod-
uct corrosion. Observe the following precautions to ensure safety.
·Never use combinations of different batteries, or old batteries together
with new batteries.
·Never use batteries that are not specified in the instruction manual.
·If liquid should leak from the battery, wipe up the leakage with a cloth and
then replace the battery accordingly.
·Replace the batteries immediately when the time for replacement
arrives.
·Remove the batteries when the projector is not to be used for a long
period of time.
·Never apply heat to the batteries, or place them in naked flames or water.
·Ensure that the batteries are inserted in accordance with the correct
polarity (+ and -).
·If any liquid that has leaked from a battery gets onto the hands, wash it
off immediately with water.
Batteries must be disposed of in accordance with the regulations in effect
in each relevant area.
●Ensure that the electric plug and connectors have been discon-
nected from their sockets when performing maintenance tasks.
Failure to observe this may result in electric shocks.
Caution
Confirmation

12 - Safety Precautions
Safety Precautions
●Using the projector outside of the permissible temperature range (+5°C to +40°C) may
result in unstable display and excessive loads being placed on the fan, leading to
damage to the equipment.
●Storing the projector outside of the permissible temperature range (-10°C to +60°C)
may result in damage of the case. Take special care to avoid placing the equipment in
direct sunlight for a long period of time.
●Do not use the projector with the lens cover still in place. The heat generated by the
lens may cause the cover to become malformed.
●The liquid crystal display panel has been manufactured with high-accuracy technol-
ogy and contains more than 99.99% active pixels. However, note that there is a possi-
bility of 0.01% of missing pixels and pixels that will be constantly illuminated.
