Important Information
iii
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.
CAUTION
Hot air is from the exhaust vent. When using or installing
the projector, the following precautions should be taken.
− Do not put any flammable objects or spray cans near
the projector, hot air is exhausted from the air vents.
− Keep the exhaust vent at least 3 feet (1 m) away from
any objects.
− Do not touch peripheral parts in the exhaust vents,
especially screws and metallic parts. These areas will
become hot while the projector is used.
− Do not put anything on the cabinet. Objects put on
the cabinet will not only get damaged but may also
cause a fire hazard.
Cooling fans are provided to cool down the projector. The
fans’ running speed is changed according to the tem-
perature inside the projector.
IMPORTANT!
Clean the Filter Regularly!!
The projector uses a lamp which generates significant
heat. The cooling fans and air vents are provided to dis-
sipate 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 and on or in the filter.
When the “Please clean filter” message is displayed, stop
using the projector immediately and clean or replace the
filter.
Blocking the air vents and leaving the projector un-
cleaned for a long time may not only damage the projec-
tor and may require costly repairs but may also cause
accidents or fire.
For maintenance of the filter, refer to “Option” on page 83
and “Replacing the Filters” on pages 97 – 98 .
Damages to the projector caused by using an
un-cleaned filter or improper maintenance will void
the warranty on the projector.
