After correcting the original service problem, perform thefollowing safety 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 examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)SAFETY CHECK-OUTTo Exposed Metal Parts on Set0.15 F1.5 kACVoltmeter(0.75 V)Earth GroundFig. A.

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 “CD section adjustment” and checkthat the S curve waveform is output three times.1.
