wrong with your projector.
Do not operate if smoke, strange noise or odor comes
out of your projector. It may cause fire or electric
shock. In this case, unplug immediately and contact
your dealer.
Never remove the cabinet.
This projector contains high voltage circuitry. An
inadvertent contact may result in an electric shock.
Except as specifically explained in User Manual, do
not attempt to service this product by yourself.
Please contact your dealer when you want to fix,
adjust, or inspect the projector.
Do not modify the projector.
It can lead to fire or electric shock.
Do not keep using the damaged projector.
If the projector is dropped and the cabinet is dam-
aged, unplug the projector and contact your dealer
for inspection. It may lead to fire if you keep using
the damaged projector.
Do not face the projection lens to the sun.
It can lead to fire.
Use correct voltage.
If you use incorrect voltage, it can lead to fire.
Do not place the projector on uneven surface.
Place the projector on a level and stable surface only.
Do not look into the lens when the projector is
operating.
It may hurt your eyes. Never let children look into
the lens when the projector is on.
Do not unplug the power cord during
operation.
It can lead to lamp breakage, fire, electric shock or
other trouble. Wait for the fan to stop before unplug-
ging the power cord.
Do not touch the air outlet grilles and bottom
plate.
Do not touch them or put other equipment close to
the air outlet grilles because they become hot during
operation. The heated air outlet grilles and bottomplate may cause injury or damage to other equip-
ment. Also, do not put the projector on a desk that is
easily affected by heat.
Clean the air-filter once a month.
Clean the air-filter frequently. If the filter or ventila-
tion slots become clogged with dirt or dust, the
temperature inside of the projector may rise and
cause some troubles, such as damage of inside parts,
and shortening the life of the panels.
Do not look into the air outlet grilles when
projector is operating.
Heat, dust, etc. may blow out of them and hurt your
eyes.
Do not block the air inlet and outlet grilles.
If they are blocked, heat may be generated inside the
projector, causing deterioration in the projector
quality and fire.
Place of installation

place subjected to high temperature and high hu-
midity. Please maintain an operating temperature,
humidity, and altitude as specified below.
• Operating temperature: between +41°F (+5°C)
and +95°F (+35°C).
• Operating humidity:  between 30% and 90%.
• Never put any heat-producing device under the
projector to prevent the projector from being
overheated.
• Do not install the projector at a place that is
unstable or subject to vibration.
• Do not install the projector near any equipment
that produces a strong magnetic field. Also re-
frain from installing the projector near any cable
carrying a large amount of current.

causing serious injury or damage.
• Slanting the projector more than ±10˚(right and
left) or ±30˚(front and rear) may cause trouble or
explosion of the lamp.
• Do not place the projector near air-conditioning
unit or heater to avoid the air outlet and inlet
grilles from being exposed to hot air.

• Load the batteries from - spring side, and make sure to set them tightly.
3. Replace the back cover.
CAUTION
• Use of a battery of wrong type may cause explosion.
• Only Carbon-Zinc or Alkaline-Manganese Dioxide type batteries should be used.
• Dispose of used batteries according to your local regulations.
• Batteries may explode if misused.
• Do not recharge, disassemble, or dispose of in fire.
• Be sure to handle batteries according to the instructions.
• Load batteries with the positive (+) and negative (-) sides correctly oriented as indicated on the remote control.

Operation range (of the remote control)
The maximum operation distance of the remote control is about 10 m (or about 32 feet) when the remote control
is pointed at the remote control sensor of the projector. When the remote control is pointed to the screen, the
distance from the remote control to the projector via the screen should be 6 m or less. However, the operation
distance varies depending on the type of the screen used.
