Safety Instructions
Openings in the cabinet are provided for
ventilation. To ensure reliable operation of the
product and to protect it from overheating, these
openings must not be blocked or covered.
CAUTION
Hot air is exhausted from the exhaust vent. When
using or installing the projector, the following
precautions should be taken.
– Do not put any flammable object or spray can
near the projector, as hot air is exhausted from
the air vents.
– Keep the exhaust vent at least 3' (1 m) away
from any objects.
– Do not touch peripheral parts of the exhaust
vent, especially screws and metallic parts.
These areas will become hot while the projector
is being used.
– Do not put anything on the cabinet. Objects put
on the cabinet will not only get damaged but
also may cause fire hazard by heat.
Cooling fans are provided to cool down the
projector. The fans' running speed is changed
according to the temperature inside the projector.

IMPORTANT!
Filter Maintenance!!
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 page 65 and "Maintenance and Care" on pages
66-68.
Damages to the projector caused by using an
uncleaned filter or improper maintenance will
void the warranty on the projector .
