Important Information
Cleaning
1. Turn off the projector and unplug the power cable before
cleaning the cabinet or replacing the lamp.
2. Clean the cabinet periodically with a cloth. If heavily
soiled, use a mild detergent. Never use strong deter-
gents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be
careful not to scratch or mar the lens.
4. Do not touch the projector or the power plug with wet
hand. Doing so can cause electrical shock or fire.
CAUTION
1. Do not unplug the power cable from the wall outlet or
projector when the projector is powered on.
Doing so can damage the projector.
• While projecting images
• While cooling after the projector has been turned
off.
(The POWER button LED blinks in green while the

LCD screen. The cooling fan continues to work for
90 seconds.)
2. Do not turn of the AC power for 90 seconds after the
lamp is turned on and while the POWER indicator is
blinking green. Doing so could cause premature lamp
failure.
3. Use of a wall outlet with a 20 A or more circuit breaker
is recommended.

3. Due to the lamp being sealed in a pressurized environ-
ment, there is a small risk of explosion, if not operated
correctly. There is minimal risk involved, if the unit is in
proper working order, but if damaged or operated
beyond the recommended hours, the risk of explosion
increases. Please note that there is a warning system
built in, that displays following message when you reach
a preset operating time "Lamp1 OverTime" or "Lamp2
OverTime" . When you see this message please replace
the lamp 1 or lamp 2. If the lamp does explode, smoke
will be discharged from the vents located on the back of
the unit. Do not stand in front of the vents during the
operation. This smoke is comprised of glass in particu-
late form and Mercury gas, and will not cause harm if
kept out of your eyes. If your eyes have been exposed to
this gas, please flush your eyes out with water immedi-
ately and seek immediate medical attention. Do not rub
your eyes! This could cause serious injury.
A Lamp Characteristic
The projector has a high-pressure mercury lamp as a
light source.
A lamp has a characteristic that its brightness gradually
decreases with age. Also repeatedly turning the lamp on
and off will increase the possibility of its lower
brightness.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has
been used. It will be extremely hot. Turn the projector
off and then disconnect the power cable. Allow at least
one hour for the lamp to cool before handling.
• When removing the lamp from a ceiling-mounted pro-
jector, make sure that no one is under the projector.
Glass fragments could fall if the lamp has been
burned out.
Disposing of your used product
EU-wide legislation as implemented in each
Member State requires that used electrical
and electronic products carrying the mark (left)
must be disposed of separately from normal
household waste.
This includes projectors and their electrical
accessories or lamps. When you dispose of
such products, please follow the guidance of
your local authority and/or ask the shop where
you purchased the product.
After collecting the used products, they are
reused and recycled in a proper way. This
effort will help us reduce the wastes as well as
the negative impact such as mercury con-
tained in a lamp to the human health and the
environment at the minimum level.
The mark on the electrical and electronic prod-
ucts only applies to the current European
Union Member States.
