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.

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.

IMPORTANT!

Clean the Filter Regularly!!

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 and on or in the filter.

If the projector detects that the filter is clogged, a “Filter warning” icon (red) will appear on the screen and “WARNING FILTER” indicator on the top panel will blink (see below). Stop using the projector immediately and clean or replace the filter.

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 62 and “Maintenance and Filter Cleaning” on pages 63–64.

Damages to the projector caused by using an uncleaned filter or improper maintenance will void the warranty on the projector.
