IAGRAMME SCHI:MATIQUE

1. As for the voltages of 0507, 0508 and 0513, each of themis measured in playback mode.

e Parts marked with "6" ( ) are important for main­taining the safety of the set. Be sure to replace these partswith specified ones for maintaining the safety andperformance of the set.

e Schematic diagram and Wiring Side of P.W.Board for thismodel are subject to change for improvement without priornotice.

1. Fur die Spannunqen von 0507, 0508 und 0513 wird jedevon diesen bei Einstellung auf Wiedergabe-Betriebsart ge­messen.

e Die mit .& ( ) bezelchneten Teile sind besonders wichtigfur die Aufrechterhaltunq der Sicherhsit. Beim Wechselndiessr Teile sollten die vorgeschriebenen Tells immerverwendet warden, um sowoh I die Sicherherheit als auchdie Leistung des Gerates aufrechtzuerhalten.

e Anderungen des schernatlschen Schsltplans und der Ver­drahtungsseite der Leiterplatte fur disses Modell im Sinnevon Verbesserungsn [ederzeit vorbehalten,

ANMERKUNGEN ZUM SCHEMATISCHEN SCHALTPLAN

REMARQUES CONCERNANT LE

e Widerstande:Um die Einheiten der Widerstande unter-scheiden zukennan, werden Symbole wie K benutzt, Das Symbol Kbedautat 1000 Ohm Sei Widerstiinden ohne Symbolhandelt es slch um ohmsche Widerstande.

el Kondensatoren:Zum Bezelchnen der Kondensatoreinheit wird das SymbolP benutzt: dieses Symbol P bedeutet Nanofard, Die Einheiteines Kondensators ohne Symbol ist Mikrofarad. FurElektrolytkondensatoren wird die Be-zslchnunq "Kapazitat/ Stehspannung" banutzt.

Ell Die in den einzelnen Teilen angegebenen Spannungenwerden mit einem DigitalvielfachmeBgerat zwischen dembetreffen den Tell und dem Chassis ohne Signalzuleitunggemessen.( ): AM-BetriebsartAnzeichnen, auBer ( ): UKW-Betriebsart

@

e Resistor:To differentiate the units of resistors, such svmbot.as K isused: the symbol K means 1000 ohm and the resistorwithout any symbol is ohm-type resistor.

e Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As to elec­trolytic capacitor, the expression "capacitance/withstandvoltage" is used.

e The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and thechassis with no signal given.( ): AM modeMarking except for ( ): FM mode

®e Resistance:

Pour differencier las unites de resistances, on utilise dessvrnbole tels que K: Ie svmbole I< signifie 1000 ohms et laresistance don nee sans svrnbole est une resistance de typeohm.

e Condensateur:Pour lndlquer l'unlte de condensateur, on utilise le symboleP; ce symbole P signifie micro-microfarad, et l'unite decondensateur donnse sans ce svmbole est Ie microfarad. Ence qui concerne Ie condensateur electrolytique, on utilisel'expression "tension de regime/capacite"
