SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITHMARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTSLIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR INSUPPLEMENTS PUBLISHED BY SONY.

• HOW TO CHANGE THE CERAMIC FILTERThis model is used two ceramic filters of CF2 and CF3.You must use same type of color marked ceramic filters inorder to meet same specifications.Therefore, the ceramic filter must change two pieces togethersince it's supply two pieces in package as a spare parts.

SAFETY CHECK-OUT

After correcting the original service problem, perform the followingsafety 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.

LEAKAGEThe 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 examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)
