Maintenance
The projector needs proper maintenance. You should keep the lens clean as dust, dirt 
or spots will project on the screen and diminish image quality. If any other parts need 
replacing, contact your dealer or qualified service personnel. When cleaning any part 
of the projector, always switch off and unplug the projector first.
Warning
Never open any of the covers on the projector. Dangerous electrical voltages 
inside the projector can cause severe injury. Do not attempt to service this 
product yourself. Refer all servicing to qualified service personnel.
Cleaning the Lens
Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands.
Cleaning the Projector Housing
Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth 
damped with water, or water and neutral detergent, and wipe dry with a soft, dry cloth.
Cleaning the Filter Cover
The filter cover, which is located at the side of the projector, should be cleaned after 
every 100 hours of use. If it is not cleaned periodically, it can become clogged with 
dust and prevent the projector from being ventilated properly. This can cause over 
heating and damage the projector.

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.
„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.
