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....

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.
