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 warning 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.
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
page 64 and "Maintenance and Care" on pages 65-67.
Damages to the projector caused by using an
uncleaned filter or improper maintenance will void the
warranty on the projector .
