1. SAFETY INFORMATION

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 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 to do so and refer the repair to a qualified service technician.

THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUTED PERSON.

LABEL CHECK

IMPORTANT

MYXJ type

NVXJ type

LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 32 mW WAVELENGTH: 785 nm

Additional Laser Caution

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 “ LOAD ON ” (ON:

( MYXJ type Only )

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 lighted exept when the level of signal “LOAD ” is low.

∗ Refer to page 31.
