SAFETY CHECK-OUT (US MODEL) 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)

STR-K5900P/K9900P SECTION 5 EXPLODED VIEWS
NOTE: The mechanical parts with no reference number in the exploded views are not supplied. Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. Abbreviation CND : Canadian model -XX and -X mean standardized parts, so they may have some difference from the original one. Color Indication of Appearance Parts Example : KNOB, BALANCE (WHITE). (RED) R R Parts Color Cabinets Color Accessories are given in the last of this parts list. The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Les composants identifis par une marque 0 sont critiques pour la scurit. Ne les remplacer que par une pice portant le numro spcifi.
