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 microamperes). 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” indica- tion is 0.75 V, so analog meters must have an accurate low- voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex- amples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suit- able.

When returning the unit to the customer after completing repairs, per- form this operation to clear the unit. Procedure: 1.While pressing two buttons of TUNER and MD/TAPE si- multaneously, press the 1/u button to turn the power ON. 2.The message “INITIAL” appears and initialization is per- formed. Fluorescent Indicator Tube Test Mode All fluorescent segments are tested. When this test is activated, all segments turn on at the same time, then each segment turns on one after another. Procedure: 1.While pressing two buttons of TV/SAT (US , Canadian and Australian models)* and DIRECT simultaneously, press the 1/u button to turn the power ON. 2.All segments turn on at the same time, then each segment and LED turns on one after another. 3.The message “FINISH” appears when this test is complete. *) Except US, Canadian and Australian models are TV/LD AUTO-BETICAL Check Mode (AEP model) To auto-scanning and memories of RDS station. Procedure: 1.While pressing the MEMORY button, press the 1/u button to turn the power ON. 2.The message “AUTO BET” appears and each function is se- lected one after another.
