Safety Instructions
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,
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 page 67.
Damages to the projector caused by using an
uncleaned filter or improper maintenance will void the
warranty on the projector.
