Safety Instructions Safety Precautions WARNING: The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identified with the line ( ) in the schematic diagram. For continued product safety and protection of per- sonnel injury, servicing should be made with qualified personnel. The following precautions must be observed. 1: An isolation transformer should be connected in the power line between the projector and the AC DO NOT OPERATE THIS PROJECTOR WITHOUT T line before any service is performed on the projec- HE PROTECTIVE SHIELD IN POSITION AND PROP tor.

Page 5: Circuit Protections
Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro- jector, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW902) inside of the projector to de- tect the internal temperature rising abnormally. When the internal temperature reaches near 100˚C, the thermal switch opens to stop the operation of the power supply circuit. The thermal switch cannot be reset itself automatically even if the internal temperature becomes normal. Reset the thermal switch following to the below procedure. How to reset the thermal switch 1. I nsert the sharp tool like a screwdriver into a hole on the cabinet from the cabinet bottom. 2. P ress the reset button on the thermal switch with the screw- driver.
Page 6: Warning Temperature And Power Failure Protection
Circuit Protections Warning temperature and power failure protection The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the cooling fans stop spinning, or the power supplies in the projector are failed. Led indicator WArNING lights red POWer the projector is shut down and the WArNING indicator is blinking red. When the temperature inside the projector reaches a certain level, the projector will be automatically shut down to protect the inside of the projector and the WARNING and POWER indicators start blinking. When the projector has cooled down enough (to its normal operating temperature), the POWER indicator stops blinking and lights red, The projector can be turned on again by pressing the ON/STAND-BY button. Note The WARNING indicator continues to blink even after the temperature inside the projector returns to nor- mal. When the projector is turned on again, the WARNING indicator stops blinking. Check items - Remove dust around the air filter. CAUtION - Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation DO NOT LEAVE THE PROJECTOR WITH THE AC slots are not obstructed.
Page 7: Maintenance
Maintenance Cleaning the Filter Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector. If a Filter warning icon appears on the screen, clean the filters immediately. Clean the filters by following the steps below. Turn off the projector, and unplug the AC power cord from the AC outlet. Turn the projector over and remove the filters by pulling the latches upward. Gently clean the filters by using a brush or rinse it softly. When rinsing the filters, dry they well. Replace the filters properly. Make sure that the filters are fully inserted to the projector. CAUtION Filters Do not operate the projector with the filters Pull up and remove. removed. Dust may accumulate on the optical elements degrading picture quality. Do not put anything into the air vents. Doing so P Note: may result in malfunction of the projector. When reinserting these filters, be sure that the slit part is facing the outer side. reCOMMeNdAtION We recommend avoiding dusty/smoky environments when you operate the projector. Usage in these environments may cause poor image quality.
