This appendix includes safety instructions and other important information 
about your projector.
Important Safety Instructions
Follow these safety instructions when setting up and using the projector:
■Do not look into the lens when the projector is on. The bright light can 
damage your eyes.
■Do not place the projector on an unstable cart, stand, or table.
■Do not operate the projector on its side, or while tilted to one side. 
Do not tilt the projector forward or back at a greater angle than that 
specified for keystone correction (see page 94). 
■If the projector is mounted on a ceiling, it should be installed by 
qualified technicians using mounting hardware designed for use with 
this projector.
■If you use a ceiling mount and apply adhesives to the mount to prevent 
the screws from loosening, or if you use lubricants or oils on the 
projector, the projector case may crack and the projector may fall from 
its ceiling mount. This could cause serious injury to anyone under the 
mount and could damage the projector. When installing or adjusting a 
ceiling mount, do not use adhesives to prevent the screws from loosening 
and do not use oils or lubricants.
■Do not stand on the projector or place heavy objects on it.
■Do not use the projector where it may be exposed to rain, water, or 
excessive humidity. 
■Unplug the projector from the wall outlet before cleaning. Use a dry 
cloth (or, for stubborn dirt or stains, a moist cloth that has been wrung 
dry) for cleaning. Do not use liquid or aerosol cleaners.
■Never spill liquid of any kind into the projector.
■Do not use the projector where it may be exposed to excessive dust or 
smoke. 
						

							102Notices
■Never push objects of any kind through the cabinet slots. 
■Do not use or store the projector or remote control in a hot location, 
such as near a heater, in direct sunlight, or in a closed vehicle.
■Do not block the slots and openings in the projector case. They provide 
ventilation and prevent the projector from overheating. Do not operate 
the projector on a sofa, rug, or other soft surface, or set it on top of loose 
papers, which could block vents underneath your projector. If you are 
setting up the projector near a wall, leave at least 7.9 inches (20 cm) of 
space between the wall and the air exhaust vent.
■Do not operate the projector in a closed-in cabinet unless proper 
ventilation is provided.
■If you are using two or more projectors side-by-side, leave at least 2 feet 
(60 cm) of space between the projectors to allow for proper ventilation.
■You may need to clean the air filter and vent. A clogged air filter or vent 
can block ventilation needed to cool the projector.
■Do not store the projector outdoors for an extended length of time.
■Do not use the projector outside the required temperature range of 
41 to 95 °F (5 to 35 °C). Doing so may cause an unstable display and 
could lead to projector damage.
■Do not store the projector outside the required temperature range of 
14 to 140 °F (–10 to 60 °C) or in direct sunlight for long periods of 
time. Doing so may cause damage to the case.
■Do not touch the plug during an electrical storm. Otherwise, you may 
receive an electric shock.
■Unplug the projector when it will not be used for extended periods.
■Unplug the projector from the wall outlet and refer servicing to qualified 
service personnel under the following conditions: If it does not operate 
normally when you follow the operating instructions, or exhibits a 
distinct change in performance; If smoke, strange odors, or strange 
noises come from the projector; If the power cord or plug is damaged or 
frayed; If liquid or foreign objects get inside the projector, or if it has 
been exposed to rain or water; If it has been dropped or the housing has 
been damaged.
■Except as specifically explained in this User’s Guide, do not attempt to 
service this product yourself. Refer all servicing to qualified personnel. 
Opening or removing covers may expose you to dangerous voltages and 
other hazards.
■Never open any covers on the projector except as specifically explained 
in this User’s Guide. Never attempt to disassemble or modify the 
projector. Refer all repairs to qualified service personnel. 
						

							Notices103
■Use the type of power source indicated on the projector. Use of a 
different power source may result in fire or electric shock. If you are not 
sure of the power available, consult your dealer or power company.
■If you use the projector in a country other than where you purchased it, 
use the correct power cord for that country.
■Do not overload wall outlets, extension cords, or power strips. Do not 
insert the plug into a dusty outlet. This can cause fire or electric shock.
■Take the following precautions when handling the plug: Do not hold 
the plug with wet hands. Do not insert the plug into an outlet with dust 
present. Insert the plug firmly into the outlet. Do not pull the power 
cord when disconnecting the plug; always be sure to hold the plug when 
disconnecting it. Failure to comply with these precautions could result 
in fire or electric shock.
■Do not place the projector where the cord can be walked on.
■The lamp(s) in this product contain mercury. Please consult your 
state and local regulations regarding disposal or recycling. Do not put in 
the trash.
■Do not place anything that can become warped or damaged by heat near 
the exhaust vents. Do not bring your hands or face close to the vents 
while projection is in progress.
■Before you move the projector, make sure its power is turned off, the 
plug is disconnected from the outlet, and all cables are disconnected.
■Never try to remove the lamp immediately after use because it will be 
extremely hot. Before removing the lamp, turn off the power and wait at 
least an hour to allow the lamp to cool completely.
■Do not place the source of an open flame, such as a lit candle, on or near 
the projector.
■Do not modify the power cord. Do not place heavy objects on top of the 
power cord or bend, twist, or pull it excessively. Keep the power cord 
away from hot electrical appliances.
■If the lamp breaks, ventilate the room to prevent gases contained in the 
lamp from being inhaled or coming in contact with the eyes or mouth.
■If the projector is mounted overhead and the lamp breaks, be careful to 
prevent pieces of glass from falling into your eyes when you open the 
lamp cover.
WARNING: The cords included with this product contain chemicals, 
including lead, known to the State of California to cause birth defects or 
other reproductive harm. Wash hands after handling. (This notice is 
provided in accordance with Proposition 65 in Cal. Health & Safety Code 
§25249.5 and following.)
