2、, Singapore 159936 PIONEER CORPORATION 2003 DV-565A-S RRV2791 DVD PLAYER DV-565A-S DV-565A-K THIS MANUAL IS APPLICABLE TO THE FOLLOWING MODEL(S) AND TYPE(S). ModelTypePower RequirementRegion No. Serial No. Confi rm 3rd it is not meant for the casual do- it-yourselfer. Qualified technicians have the

3、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 the r

4、epair 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 THE LI

5、MIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 780 nm Additional Laser Caution : See page 51. 1. Laser Interlock Mec

6、hanism 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 di

7、sc 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 c

8、ollector 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 in

9、terlock 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.
