When Using Mounted on the Ceiling
When the projector is used mounted on the
ceiling or installed in a high location, it is
necessary to periodically clean the air
intake and exhaust vents, and the area
around the air filter. Dust that accumulates
in intake or exhaust vents may impair
ventilation, raising the temperature inside
and posing a risk of damage or fire. Use a
vacuum cleaner or similar means to
remove dust from the intake vent and
exhaust vent.
