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 with
the 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 higherthan 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
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 bridgesoccur such as on IC pins, etc.
Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL ORIN SUPPLEMENTS PUBLISHED BY SONY.
ATTENTION AU COMPOSANT AYANT RAPPORT LA SCURIT!
LES COMPOSANTS IDENTIFIS PAR UNE MARQUE 0 SURLES DIAGRAMMES SCHMATIQUES ET LA LISTE DESPICES SONT CRITIQUES POUR LA SCURIT DEFONCTIONNEMENT. NE REMPLACER CES COM- POSANTSQUE PAR DES PICES SONY DONT LES NUMROS SONTDONNS DANS CE MANUEL OU DANS LES SUPPLMENTSPUBLIS PAR SONY.
SAFETY CHECK-OUTAfter correcting the original service problem, perform the followingsafety 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 TESTThe 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 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 examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2 V AC range are suitable. (SeeFig. A)

TipUnder normal conditions, the batteries should last for about 6 months. When the remote no longer operates the receiver, replace all batteries with new ones.
Notes Do not leave the remote in an extremely hot or humid
place.
Do not use a new battery with an old one.
Do not expose the remote sensor to direct sunlight or lighting apparatuses. Doing so may cause a malfunction.

For Schematic Diagrams.Note: All capacitors are in F unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics andtantalums.
All resistors are in and 1/4 W or less unless otherwisespecified.
% : indicates tolerance. f : internal component. 2 : nonflammable resistor. 5 : fusible resistor. C : panel designation.
A : B+ Line. B : B+ Line. Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.No mark : FM
Voltages are taken with a VOM (Input impedance 10 M).Voltage variations may be noted due to normal productiontolerances.
Waveforms are taken with a oscilloscope. Circled numbers refer to waveforms. Signal path.

For Printed Wiring Boards.Note: X : parts extracted from the component side. a : Through hole. f : internal component. : Pattern from the side which enables seeing.
Indication of transistor.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.(In addition to this, the necessary note is printed in each block.)
Note:The components identi-fied by mark 0 or dot-ted line with mark 0 arecritical for safety.Replace only with partnumber specified.
Note:Les composants identifispar une marque 0 sont cri-tiques pour la scurit.Ne les remplacer que par unepice por tant le numrospcifi.
Caution:Pattern face side: Parts on the pattern face side seen from(Side A) the pattern face are indicated.Parts face side: Parts on the parts face side seen from(Side B) the parts face are indicated.
