11.3.2 How to clean the automatic cleaning
fi
lter
Preparations
Check the amount of dust through the dust check window of the
fi
lter cover and clean it, if necessary. Before cleaning the
fi
lter, be
sure to unplug the power cord from the outlet.
•
Wen the dust box of the automatic cleaning
fi
lter is
fi
lled up with dust, the cleaning ability decreases. If you use the projector
in such a state, the
fi
lter is covered by the dust and the temperature inside the product abnormally rises, damaging the internal
parts and components and affecting the panel’s lifetime, resulting in a breakdown.
•
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 lamps are off to protect the internal parts and components.
