• The machine'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. If the lamp explodes and you are either injured from broken pieces of glass, think
you have gotten glass particles or mercury vapour in your eyes, or have inhaled glass particles
or mercury vapour, contact a doctor immediately.
• 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
machine 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.
• The lamp is a glass product. Do not touch the glass surface with bare hands, hit it forcefully, or
damage it. For details about what to do if a lamp has exploded, see page 73 "Operating
Precautions".
• This projector's lamp contains trace amounts of environmentally harmful inorganic mercury. Be
careful not to break used lamps, and dispose of them in accordance with local regulations or
contact your sales representative or service representative.
When the lamp is due for replacement, the message "The lamp is reaching the end of its life. Please
change it." is displayed. Change the lamp as instructed.
When [Lamp Power] in [Energy Saving Settings] is specified as [Stnd.], replace the lamp after
approximately 3,500 hours. When the setting is [Eco], replace it after approximately 5,000 hours.
However, depending on the characteristics of the lamp and how the lamp is used, the image may
become dim or the lamp may go out before the message is displayed. We recommend preparing a
spare lamp, just in case.
Do not repeatedly turn off the projector immediately after the lamp is lit, or turn on the projector
immediately after turning it off. Doing so may damage the lamp or shorten its life.
Furthermore, if the lamp is used for an extended period of time, the image may darken or the lamp may
burn out. If this happens, replace the lamp with a new one.
1. Turn over the projector and place it on a flat surface so that you can see the bottom of the
projector.
