Maintenance
Cleaning of the filter
Clean dust from the filter.
Before cleaning the filter, be sure to turn off the power
of the projector and unplug the power cord from the
outlet.
Clean the filter frequently (at least once a month).
Dust settling on the filter causes the temperature
inside the projector to increase abnormally, damaging
the internal parts and components and affecting the
panel’s lifetime, resulting in a breakdown.
t When the temperature inside the projector is
abnormally high, the projector may automatically
turn off and go into the standby mode where the
light source lamp is off to protect the internal parts
and components.
