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!! 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 vent to prevent dust from getting inside of the projector. CAUTION Hot air is exhausted from the exhaust vents. 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 vents at least 3' (1 m) away from any objects. - Do not touch peripheral parts of the exhaust vents, 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. - D o not cover vents with papers or other materials. - Make sure that there are no objects under the projector. An object under the projector may prevent the projector from taking cooling air through bottom vent. - When detaching the adjustable feet, always keep at least 50 mm between the bottom of the projector and installation surface. Cooling fans are provided to cool down the projector. The fans' running speed is changed according to the temperature inside 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, the icon as shown in Fig. 1 appears on the screen and WARNING FILTER indicator lights up (see below), indicating that cleaning or replacing the filter is necessary. If the projector detects that the filter is clogged, the icon as shown in Fig. 2 appears on the screen and WARNING FILTER indicator lights up (see below). Stop using the projector immediately and replace the electrostatic honeycomb filter and the electrostatic pleated 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 68 and "Maintenance and Care" on pages 72-74. Damages to the projector caused by using an uncleaned filter or improper maintenance will void the warranty on the projector.
