2 SAFETY CHECK-OUT After correcting the original service problem, perform the following 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 as described below. LEAKAGE The AC leakage from any exposed metal part to earth Ground and from all exposed metal parts to any exposed metal part having a return 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 RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

Leave for one hour with the power supplied. (Aging) 3. Measure the voltage at the respective measuring points and adjust RV301 (L-CH) and RV401 (R-CH) so that the voltages become within the ranges shown in the following table. Adjust to the voltage with the highest priority shown in the table as much as possible.

Leave for another 30 minutes if the adjustment control has been rotated. 5. Measure the voltage again and check that it is within the adjusting value. If outside, repeat from step 3 again. 6. Be sure to perform aging for more than 30 minutes if the adjustment control has been rotated. Finally check the voltage before ending the adjustment.
