MJ-L11 2 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 nm Control method of the current through a laser diode. 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-diodes 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 fix the rated output level. Laser Interlock Switch The loading position detect switch S101 is set to Ò LOAD ON Ó (ON: low level, OFF: high level) position, IC104 get the Ò LOAD Ó signal, and hand the laser Ò LDON Ó signal to No. 9 terminal (LDON) of the Laser pickup assy. Then a laser diode can be lighted exept when the level of signal ÒLOAD Ó is low. Additional Laser Caution 1.
