Lamp replacement (Continued)
The product’s light source is a mercury lamp that lights at increased internal pressure. Be sure
to fully understand the following characteristics of the lamp and handle it with extreme care.• The lamp may burst with a loud noise due to impact or deterioration, or fail to light at
the expiration of its life.
•H ow long it takes before the lamp bursts or the life expires may vary greatly by lamp.
Some may burst shortly after first use.
• Burst is likely to happen if the lamp is used after the replacement period has elapsed.
• When the lamp bursts, the broken pieces of glass may get inside the product or be
released outside from the openings for ventilation.
• When the lamp bursts, a slight amount of mercury gas enclosed in the lamp along with
glass dust may be released from the openings for ventilation.■
Immediately replace the lamp when a sign appears on the screen.•When the replacement time approaches, a message will appear on the scree\
n.
• The risk of burst will increase if the lamp is continuously used without being replaced.
•F requently check the used hours and prepare spares when the replacement time
approaches. (Refer to “Status display”. 
p.48
)
■
When the lamp is broken• If glass components, including a lamp and a lens, should break, handle the broken
pieces with care to avoid injury and contact your dealer for repair service.
• In the event of lamp burst, unplug the product from the wall outlet, leave and completely
ventilate the room. Then, thoroughly clean the area around the projector and discard
any edible items placed in that area.
• When the lamp bursts, consult a doctor if glass dust or mercury gas gets into your eyes
or you breathe it.Lamp replacementA lamp is consumable supplies. If used for extended periods, images will appear dark, and
the lamp could burn out. This is characteristic of a lamp, and is not malfunction. (The lifetime
of the lamp depends on condition of use.) If this happens, replace it with a new one
.

.
Attempting to clean/replace the lamp at a high site by yourself may cause you to fall
down, thus resulting in injury.
■ Lens cleaning•Clean the lens with a commercially available blower and/or
lens cleaner.
• The lens is easily scratched, so do not rub it with hard objects,
or strike it.■ Main unit cleaning•Clean the main unit after unplugging the power cord.
• Wipe dirt off the main unit gently with a soft cloth.
• Do not wipe the main unit with a damp cloth. Doing
so may allow water to get inside, resulting in an
electric shock or failure.
• Do not use benzene, thinner and the like as they may
deform or discolor the unit or damage the paint
surface.
• When using a chemically treated cloth, follow the
precautions included with the cloth.Lens and main unit cleaning
