Unleaded solder melts at a temperature about 40C higher thanordinary 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 if theheated tip is applied for too long, so be careful! Strong viscosityUnleaded 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.CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation exposure.Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat.Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270Cduring repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering.Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.This appliance is classified asa CLASS 1 LASER product.The CLASS 1 LASERPRODUCT MARKING islocated on the rear exterior.RadioFans.CN 收音机爱 好者资料库3AVD-K600PSAFETY CHECK-OUTAfter 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.NOTES 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 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 CHECKThe 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 OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveform is output several times.LEAKAGE TESTThe 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 microampers).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 examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)Fig. A.
