About lamp
Maintenance
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 explode with a loud noise due to impact or deterioration, or fail to light at
the expiration of its life.
• How long it takes before the lamp explodes or the life expires may vary greatly by lamp.
Some may explode shortly after first use. (Free replacement is available if the lamp
explodes within the warranty period. Contact the dealer from whom you purchased the
product in such a case.)
• Explosion is likely to happen if the lamp is used after the replacement period has elapsed.
• When the lamp explodes, the broken pieces of glass may get inside the product or be
released outside from the openings for ventilation.
• When the lamp explodes, 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 screen.
• The risk of explosion will increase if the lamp is continuously used without being replaced.
• Frequently check the used hours and prepare spares when the replacement time
approaches. (Refer to “Status display”. p.33 )
■ 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 explosion, 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 explodes, consult a doctor if glass dust or mercury gas gets into your
eyes or you breathe it.
Lamp replacement
A 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.
WARNING
• If the projector is mounted on a ceiling, request a lamp replacement from your projector dealership.
• When replacing, always use lamp “TLPLW3” (sold separately).
CAUTION
• If you have been using the projector, the lamp will be very hot, and may cause burn injuries.
Wait for the lamp to cool (for longer than 1 hour) before replacing it.
• If the lamp should break, please handle with care to avoid injury due to broken pieces and
contact your dealer for repair service.
