■ 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 con- verter 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.
■ Specifications technical Specifications Projector type Multimedia Projector dimensions 15.75” x 5.75” x 13.6” (400,0 mm x 146.0 mm x 346.0 mm) (not including raised portions) (W x H x d) Net Weight 16.5 lbs (7.5 kg ) LCd Panel System 0.74”...
■ Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. ● Fuse A fuse(F601) is located inside of the projector. When the Fuse (F601) POWER indicator is not lightning, the fuse may be opened.
Circuit Protection Lamp cover switch ● The lamp cover switch (SW8803) cuts off the drive signal to the lamp circuit when the lamp cover is removed or not closed completely. After opening the lamp cover for replacing the lamp unit, Lamp cover switch place the lamp cover correctly otherwise the projector can not turn on.
■ Maintenance and 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.
Maintenance and Cleaning Cleaning the RGB panels Blemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of the screen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality. This projector is equipped with the RGB panel cleaning holes on the bottom for cleaning of the internal parts (such as optical components) of the projector.
Maintenance and Cleaning Clean by using the Cleaning function in the Setting Menu Cleaning Turn the projector on and press the MENU button to display the On-Screen Menu. Select the Setting Menu with the Point buttons. Press the Point or OK buttons to access the submenu items.
Maintenance and Cleaning Warning Indicator The WARNING indicator shows the state of the function that protects the projector. Check the state of the WARNING indicator and the POWER indicator to take proper maintenance. the projector is shut down and the WARNING indicator is blinking red. When the temperature inside the projector reaches a certain level, the toP CoNtRoL projector is automatically shut down to protect its inside.
Maintenance and Cleaning Cleaning the Air Filters The air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in a buildup of internal heat and adversely affect the life of the projector.
Maintenance and Cleaning Resetting the Filter Counter Be sure to reset the Filter counter after cleaning or replacing the air filter. Filter counter Turn the projector on and press the MENU button to display the On-Screen Menu. Select the Setting Menu with the Point buttons.
Screws oRdER REPLACEMENt LAMP Replacement lamp can be ordered through your dealer. When ordering a projection lamp, give the following information to the dealer. Model No. of your projector: PLV-Z3000 ● Replacement Lamp type No.: PoA-LMP135 ● (Service Parts No. 610 344 5120)
Lamp Replacement Lamp Replacement Counter Be sure to reset the lamp replacement counter after the lamp is replaced. When the lamp replacement counter is reset, the LAMP REPLACE indicator stops lighting. Lamp counter reset Turn the projector on and press the MENU button to display the On-Screen Menu.

■ Optical Adjustment Before taking optical adjustments below, remove the Cabinet Top following to the "Mechanical Disassemblies". Adjustments require a 2.0mm hex wrench, Philips Screwdriver and a slot screwdriver. When you adjust Integrator lens or Relay lens adjustment, you need to disconnect some connectors and FPC cables of LCD panels on the main board. Note: Do not disconnect connectors on the main board, because the projector can not turn on or operate properly for adjustment.
