Replacing the Lamp
• Before replacing the lamp, turn off the power and wait at least one hour to allow the product to
cool completely. If it is not completely cool, you may burn or injure yourself due to the inside of
the product and lamp unit being hot. If you replace the lamp without unplugging the power
cord from the power outlet, electric shock or explosion may occur.
• Be careful when handling the used lamp so that it does not break. If it breaks, it may cause
injury.
• Contact your sales or service representative to clean or replace parts for a projector that is
installed on a wall or ceiling.
• Do not attempt to clean or replace parts for a projector that is installed in a high location
on a wall or ceiling. Doing so may cause it to fall down, resulting in an injury.
• Do not open the lamp cover of a projector that is installed on a wall or ceiling. Doing so
may cause the lamp cover to fall down. If the lamp is broken, pieces of glass may fall and
cause an injury.
• Be sure to always use a dedicated replacement lamp that is new when replacing the lamp. If
you use a lamp that is not dedicated, it may result in an explosion and injury.
• The product's light uses a mercury vapor lamp that becomes high pressure when it is turned on.
The lamp has the following characteristics, so be sure to handle it with care after understanding
the contents.
• Deterioration or shock can cause the lamp's life span to end or the lamp to explode. If the
lamp explodes, it may make a big noise.
• The time that it takes for the lamp to reach its life span or explode depends on each
individual lamp and its operating conditions. It is possible that it might explode the first
time it is used.
• If you use the lamp past its replacement period, the possibility of explosion increases.
• If the lamp explodes, broken glass pieces may be scattered around the inside of the
product and ejected from the vent or other opening.
• If the lamp explodes, a very small amount of mercury vapor in the lamp tube and broken
glass pieces may be ejected from the vents or other opening.
