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 (SW90) inside of the projector to detect the internal temperature rising abnormally.
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. - If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector.
Page 7: Maintenance
Maintenance Cleaning the Filter Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes 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 filter immedi- ately.
Page 8: Lamp Replacement
Maintenance Lamp Replacement When the projection lamp of the projector reaches its end of life, Top Control the Lamp replacement icon appears on the screen and LAMP REPLACE indicator lights yellow. Replace the lamp with a new one promptly. The timing when the LAMP REPLACE indicator LAMP REPLACE should light is depending on the lamp mode.
Page 9: Resetting The Lamp Counter
Maintenance Resetting the Lamp Counter Be sure to reset the Lamp counter after the lamp is replaced. When the Lamp counter is reset, the LAMP RE- PLACE indicator stops lighting and the Lamp replacement icon disappears. Lamp counter Press the MENU button to display the On-Screen Menu. Use the Point 7 8 buttons to move the red framed pointer to the Setting Menu icon.
Page 10: Cleaning
Maintenance Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray.
Page 11: Security Function Notice
Security Function Notice Security Function Disable This projector provides security functions such as "Key lock", "PIN code lock" and "Logo PIN code lock". When the projector has set these security function on, you are required to enter correct PIN code to use the projector. If you do not know the correct PIN code to the projector, the projector can no longer be operated or started.
