Check leakage asdescribed below.LEAKAGE The AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed met

13、al part having areturn to chassis, must not exceed 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.1.A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers instructions to use theseinstruments.2.A battery-operated AC milliam

The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are

ELECTRICAL PARTS LIST90Unleaded solderBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating

22、 the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size.) : LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher thanordinary solder.Ordinary solder

23、ing irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful! Strong vis

24、cosityUnleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc. Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.4RCD-W10SECTION 1SER

25、VICING NOTENOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNITThe laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electr

26、ostatic break-down and alsouse the procedure in the printed matter which is included in therepain parts.The flexible board is easily damaged and should be handled withcare.NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surfac

27、e by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.The emission check enables continuous checking of the S curve.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in

28、“CD section adjustment” and checkthat the S curve waveform is output three times.MessageC12/Cannot CopyC13/Rec ErrorC14/TOC ErrorC41/Cannot CopyC71/Din UnlockExplanationYou are trying to record a disc thatcannot be played back in DECK-Aor with an external device, such asCD-ROM or VIDEO CD.
