2 1 23 4 1234 C D F A B E XV-HTD5 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 CLASS1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. 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 clamp- status detection switch (S11 on the TRSB 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 S11 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 (S5817 ON in the KEYB assy), with the above requirements sat- isfied. 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 81 on service manual RRV2634.

(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 ......................................................
