XR-VS500D 2 1. SAFETY INFORMATION Printed on the Rear Panel LABEL CHECK LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 655 nm FOR CD : MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 785 nm Additional Laser Caution 1. Inside detection switch (S201 on the SMEB assy) and loading- status detection switch (S9503 on the MOTOR assy) are detected by the microprocessor (IC11 in the DVDM assy). ¥ To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S9503 is shorted to +5V). The 655 nm laser diode for DVD oscillation will continue if pin 19 of IC1 is shorted to +5V (fault condition) in the DVDM assy. The 785 nm laser diode for CD oscillates if pin 20 of IC1 is shorted to +5V in the DVDM assy. In the test mode * , the laser diode oscillates when microproces- sor detects a PLAY signal, or when the PLAY key is pressed (S5931 ON in the DISPLAY assy), with the above requirements satisfied. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. * : Refer to page 82 on the service manual RRV2329. 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 LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. 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.

XR-VS500D 3 2. CONTRAST OF MISCELLANEOUS PARTS Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. Screws adjacent to mark on product are used for disassembly. Reference Nos. indicate the pages and Nos. in the service manual for the base model. NOTES: When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 561 473 R50 1R0 5621 560 47k 0.5 1RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x 10 3 R50 1R0561 473 5.62k RN1/4PC F562 x 10 1 5621 CONTRAST TABLE XR-VS500D/YPWXJ, YPWXJN and XR-A9800D/KUCXJ are constructed the same except for the following : Part No. Ref.
