Safety Instructions
Air Circulation
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. 
IMPORTANT!
Filter Maintenance!!
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, 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.
Exhaust Vent
(Hot air exhaust)
Air flow
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 55 and “Maintenance and Care” on pages 
56–58.
Damages to the projector caused by using an 
uncleaned filter or improper maintenance will 
void the warranty on the projector .
