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. 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. LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 780 nm Additional Laser Caution 1. Laser Interlock Mechanism - 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 disc 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 collector 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 interlock 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.

(In the case of no amount instructions, apply as you think it appropriate.) 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%). 560 Ω→56 × 10 1 →561 ........................................................ RD1/4PU 5 6 1 J 47k Ω→47 × 10 3 →473 ........................................................ RD1/4PU 4 7 3 J 0.5 Ω→R50 ..................................................................................... RN2H R 5 0 K 1 Ω→1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω→562 × 10 1→5621 ......................................................
