3) You can change the AM tuning scale to 9 kHz or 10 kHz. After tuning in any AM station, turn off the receiver. While holding down PRESET TUNING + or TUNING +, press ?/1. All preset stations will be erased when you change the tuning scale. To reset the scale to 10 kHz (or 9 kHz), repeat the procedure.

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 THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERSAPPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTSPUBLISHED BY SONY.
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 groundand from all exposed metal parts to any exposed metal part havinga 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 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)
SAFETY CHECK-OUT 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 solderBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size.)
: LEAD FREE MARKUnleaded solder has the following characteristics.• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350°C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful!
• Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

SECTION 5ELECTRICAL PARTS LIST
The components identified by mark 0 ordotted line with mark 0 are critical for safety.Replace only with part number specified.
When indicating parts by reference number,please include the board name.
NOTE:• Due to standardization, replacements in the
parts list may be different from the partsspecified in the diagrams or the componentsused on the set.
• -XX, -X mean standardized parts, so they mayhave some difference from the original one.
• Items marked “*” are not stocked since theyare seldom required for routine service. Somedelay should be anticipated when ordering theseitems.
• COILSuH: µH
• RESISTORSAll resistors are in ohms.METAL: metal-film resistorMETAL OXIDE: Metal Oxide-film resistorF: nonflammable
