Design and specifications are subject to change without notice.
Unleaded solderBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating 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 MARK
Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than
ordinary solder.Ordinary soldering 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 ifthe heated tip is applied for too long, so be careful!
Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.
Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
After correcting the original service problem, perform the followingsafety checks before releasing the set to the customer:Check the antenna terminals, metal trim, metallized knobs, screws,and all other exposed metal parts for AC leakage. Check leakage asdescribed below.
LEAKAGE
The AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal 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 milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The limit indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT
The 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 electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused onthe disc reflective surface 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.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECK
Carry out the S curve check in CD section adjustment and checkthat the S curve waveform is output several times.
