SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITHMARK ! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTSLIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERSAPPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTSPUBLISHED BY SONY.

TABLE OF CONTENTS

After correcting the original service problem, perform thefollowing 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 asdescribed below.

LEAKAGE

The AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn 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 RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.

2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

SECTION 2TEST MODE

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 onone after another.

* Procedure:While depressing the SET UP and the SOUND FIELD MODEbuttons simultaneously, press the power 1/u button to turn onthe main power. All segments turn on at the same time, then eachsegment turns on one after another.
