6 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. SAFETY CHECK-OUT (US model only) To Exposed Metal Parts on Set 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.. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 0.5 µf.5 kω Earth Ground AC Voltmeter (0.75 V) Fig. A. Using an AC voltmeter to check AC leakage. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.. 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-6Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A) 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. EXTENSION CABLE AND SERVICE POSITION When repairing or serving this set, connect the jig (extension cable) as shown below. Connect the Digital board (CN202) and the E-Vol board (CNP402) with the extension cable (Part No. J A). J A CN202 E-VOL board CNP402 DIGITAL board 6
