Epson Powerlite 78 Multimedia Projector Users Guide

							Notices111
■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.)
