6.2 Replacing The Lamp
Prepare a new lamp.
Type number: DT01461.
WARNING
• The projector uses a high-pressure mercury lamp (Hg-Lamp).
• The lamp can break with a loud bang, or burn out, if jolted or scratched, handled while hot,
or worn over time. Note that each lamp has a different lifetime, and some may burst or burn
out soon after you start using them.
Hg - Lamp contains mercury. Manage in accordance with local disposal laws. See
www.lamprecycle.org
• To reduce the risk of electrical shock, always turn the projector off and disconnect the
power cord before changing the lamp.
• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before
replacing the lamp.
• To reduce the risk of injuries to fingers and damage to internal components, use caution
when removing lamp glass that has shattered into sharp pieces. Before replacing the lamp,
clean the lamp compartment and dispose of cleaning materials. Be careful of sharp edges
in the lamp compartment. Wash hands after lamp replacement.
• If the lamp should break (it will make a loud bang when it does), ventilate the room well,
and make sure not to inhale the gas or fine particles that come out from the projector's vent
holes, and not to get them into your eyes or mouth.
• Only certified lamps are tested with this projector. Use of other lamps may cause electrical
shock and fire.
• Be sure to place the projector on a flat surface to replace the lamp.
Replace Process:
1. Turn the power off and disconnect the power cord from
the wall socket. If the lamp is hot, avoid burns by
waiting for approximately 45 minutes until the lamp has
cooled.
2. Prepare a new lamp. If the projector is mounted in a
high position, or if the lamp has broken, also ask the
dealer to replace the lamp.
3.
Loosen the screw of the lamp door. Refer to the right
figure to identify the screw.
4. Remove the lamp door from the projector.
WARNING
• Do not turn the power on with the lamp door
removed.
• Do not insert your fingers between the lamp and the
projector. It may cause injuries.
