T-ZZE JUNE 2003 printed in JapanRadioFans.CN 收音机爱 好者资料库 DV-565A-S212341234CDFABE SAFETY INFORMATIONThis service manual is intended for qualified service technicians ; it is not meant for the casual do-it-yourselfer. Qualified technicians have
4、 the necessary test equipment and tools, and have been trainedto 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 mayvoid the warranty. If you are not qualified to perform
5、the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician.WARNING ! THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING TH
6、E LIMIT FOR CLASS 1.A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. LASER DIODE CHARACTERISTICSFOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nmFOR CD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 780 nmAdditional Laser Caution : See page 51.1. Laser Interlock Mech
7、anism Loading switch (S101 on the LOAB Assy) is used for interlock mechanism of the laser. When this switch turned ON in SW2 (CLOSE) side (OPEN signal is 0V and CLOSE signal is 3.5V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the dis
8、c judgment and disc playback. When player is power ON state and laser diode is not completely oscillating, 780nm laser diode is always oscillating by half power. Laser diode is driving with Q201 (650nm LD) and Q211 (780nm LD) on the DVDM Assy. Therefore, when short-circuit between the emitter and co
9、llector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) In the test mode , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The int
10、erlock mechanism mentioned above becomes invalid in this mode.2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam.LABEL CHECK(Printed on the Rear Panel)RadioFans.CN 收音机爱 好者资料库 DV-565A-S356785678CDFABE Important symbols for good
