18、e set to the customer:Check the antenna terminals, metal trim, “metallized” knobs,screws, and all other exposed metal parts for AC leakage.Check leakage as described below.LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part

19、 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.

20、 The Data Precision 245digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of a VOMor battery-operated AC voltmeter. The “limit” indication is 0.75V, so analog meters must have an accurate low-voltage scale.The Simpson 250 and Sanwa SH-63Trd are exampl

24、 printed circuit boards may not come printed withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics.

Strong viscosityUnleaded solder is more viscou-s (sti

26、cky, less prone to flow)than ordinary solder so use caution not to let solder bridges oc-cur 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.4STR-DA5000ES1.SERVICING NOTES.52.GENERALLocation of Control
