Page 8: Air Filter Care And Cleaning
● Air filter care and cleaning ● A A ir fi er ca and c a ing The Air Filter prevents dust from accumulating on the optical elements inside the LCD Projection Monitor. Should the Air Filter become clogged with dust particles, it will reduce the Cooling Fans' effectiveness and may result in internal heat building up and effect on the life of the LCD Projection Monitor.
Page 9: Cleaning The Lcd Projection Monitor
● Cleaning the LCD Projection Monitor ● Clean g the LCD Pr e tion M Be sure to disconnect the AC Power cord from the AC outlet before cleaning the LCD Projection Monitor. ● Gently wipe the screen and the cabinet with a soft dry clean cloth.
Page 10: Optical Parts Care And Cleaning
● Optical parts care and cleaning ● O O pti al parts s care and clea a ning 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 other particles using air spray.
