SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check 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 TEST 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 lowvoltage 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 2 V AC range are suitable. (See Fig. A)

NOTE: · Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. · -XX and -X mean standardized parts, so they may have some difference from the original one. · RESISTORS All resistors are in ohms. METAL:Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F:nonflammable · Items marked "*" are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. · SEMICONDUCTORS In each case, u : µ, for example: uA.. : µA.. uPA.. : µPA.. uPB.. : µPB.. uPC.. : µPC.. uPD.. : µPD.. · CAPACITORS uF : µF · COILS uH : µH · Abbreviation CND : Canadian model AR : Argentina model AUS : Australian model CH : Chinese model MX : Mexican model SP : Singapore model TW : Taiwan model
