The resistor R105 on the CORE MAIN UNIT ASSY (For MD mechanism assy) are for the limiting of current through a laser diode. Control method of the laser output power The laser pickup assy provide the photo-dio

7、des and APC (Auto Power Control) circuit. The photo-diode detect output of the laser diode then IC104 control the APC circuit according to the signal voltage of the photo-diode via IC101. The Variable resistancer on the FPC in the Laser pickup assy can be adjusted the output level of Laser diode to

8、fix the rated output level. Laser Interlock Switch The loading position detect switch S101 is set to “ LOAD ON ” (ON: low level, OFF: high level) position, IC104 get the “ LOAD ” signal, and hand the laser “ LDON ” signal to No. 9 terminal (LDON) of the Laser pickup assy. Then a laser diode can be l

9、ighted exept when the level of signal “LOAD ” is low. Additional Laser Caution This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and

10、safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying t

11、o do so and refer the repair to a qualified service technician. Refer to page 30. IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUTED PERSON. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 32 mW WAVELENGTH: 785 n
