Air Circulation

The projector uses a lamp which generates significant
heat. The cooling fans and air vents are provided to
dissipate the heat by drawing air into the housing and the
filter is located in the intake vents to prevent dust from
getting inside of the projector.
In order to care for the projector appropriately, regular
cleaning is required. Remove any dirt or dust that has
accumulated on the projector.
If the projector reaches a time set in the timer setting, a
Filter replacement icon (Fig. 1) appears on the screen and
WARNING FILTER indicator on the top panel lights up (see
below), indicating that the filter replacement is necessary.
If the projector detects that the filter is clogged and
no scroll is left in the filter cartridge, a Filter cartridge
replacement icon (Fig. 2) appears on the screen and
WARNING FILTER indicator on the top panel lights up (see
below). Stop using the projector immediately and replace
the filter cartridge.
Blocking the air vents and leaving the projector uncleaned
for a long time may not only damage the projector and may
require costly repairs but may also cause accidents or fire.
For maintenance of the filter, refer to "Filter counter" on
Exhaust Vent
