2 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.5 ma (5 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-54A. 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.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 25 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.

Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK OR DOTTED LINE WITH MARK ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. : LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 4 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 35 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. 2

Procedure: While depressing the PRESET TUNING and the DIMMER buttons simultaneously, press the power?/1 button to turn on the main power. The message FACTORY appears and the present contents are reset to the default values. AM CHANNEL STEP 9 khz/1 khz SELECTION MODE Either the 9 khz step or 1 khz step can be selected for the AM channel step. Procedure: Set the FUNCTION to AM. Turn off the main power. While depressing the TUNING+ button or the PRESET TUNING+ button, press the power?/1 button to turn on the main power. Either the message 9 k STEP or 1 k STEP appears. Select the desired step. This mode is only for US, Canadian, Australian and E models. FLUORESCENT INDICATOR TUBE TEST MODE All fluorescent segments are tested.
