The dust filter should be cleaned or replaced periodically (suggest 
after every 500 hours or 3 months of use). If it is not cleaned

projector from being ventilated properly. This can cause over 
heating and damage the projector. If the projector is used in a dusty

it out as the illustration.

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.
