Appendix
Replacing the Lamp
As the projector operates over time, the brightness of the projector lamp 
gradually decreases and the lamp becomes more susceptible to breakage. 
We recommend replacing the lamp if a warning message is displayed. Do 
not attempt to replace the lamp yourself. Contact the qualified service 
personnel for replacement.
Note
„The lamp is extremely hot right after turning off the projector. If you touch the lamp, you may
scald your finger. When you replace the lamp, wait for at least 45 minutes for the lamp to cool
down.
„Do not touch the lamp glass at any time. The lamp may explode due to improper handling,
including the touching of the lamp glass.
„Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is
no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their
lifetime in a shorter period of time than other similar lamps.
„A lamp may explode as a result of vibration, shock or degradation as a result of hours of use
as its lifetime draws to an end. Risk of explosion may differ according to the environment or
conditions in which the projector and lamp are being used.
„Wear protective gloves and eyeglasses when fixing or detaching the lamp.„Faster on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 5 minutes to
turn off the projector after powering on.
„Do not operate the lamp in proximity to paper, cloth, or other combustible material nor cover it
with such materials.
„Do not operate the lamp in an atmosphere containing an inflammable substance, such as
thinner.
„Thoroughly ventilate the area or the room when operating the lamp in an oxygen atmosphere
(in the air). If ozone is inhaled, it could cause headaches, nausea, dizziness, and other
symptoms.
„The inorganic mercury is involved in the lamp. If the lamp bursts, the mercury inside the lamp
will be exposed. Leave the area immediately if the lamp shatters while being operated and
ventilate the area for at least 30 minutes in order to avoid the inhalation of mercury fumes.
Otherwise it could be harmful to user’s health.
