WASH HANDS AFTER HANDLING
Note for US Residents
The lamp in this product contains mercury.
Please dispose according to Local, State or
Federal Laws.
Lamp Replacement
1. Use the specified lamp for safety and performance.
2. To replace the lamp, follow all instructions provided on
the user's manual.
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.
About High Altitude mode
• Set [Fan Speed Mode] to [High Altitude] when using the
projector at altitudes approximately 5500 feet/1600 meters
or higher.
Using the projector at altitudes approximately 5500
feet/1600 meters or higher without setting to [High Alti-
tude] can cause the projector to overheat and the projec-
tor could shut down. If this happens, wait a couple minutes
and turn on the projector.
• Using the projector at altitudes less than approximately
5500 feet/1600 meters and setting to [High Altitude] can
cause the lamp to overcool, causing the image to flicker.
Switch [Fan Speed Mode] to [Auto].
• Using the projector at altitudes approximately 5500
feet/1600 meters or higher can shorten the life of internal
parts such as the lamp.
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 house-
hold 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 contained 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.
