1-12-1 H9641SCNOTE: CBA AND PWB MEANS PRINTED WIRINGBOARD.Standard NotesWARNINGMany electrical and mechanical parts in this chassishave special characteristics. These characteristics oftenpass unnoticed and the protection afforded by themcannot necessarily be obtained by using replacementcomponents rated for higher voltage, wattage, etc.Replacement parts that have these special safetycharacteristics are identified in this manual and itssupplements; electrical components having suchfeatures are identified by the mark " # " in the schematicdiagram and the parts list. Before replacing any of thesecomponents, read the parts list in this manual carefully.The use of substitute replacement parts that do nothave the same safety characteristics as specified in theparts list may create shock, fire, or other hazards.Capacitor Temperature MarkingsMark Capacitychange rateStandardtemperatureTemperaturerange(B)(F)±10%+30 - 80%±15%+30 - 80%20°C20°C20°C20°C-25~+85°C-25~+85°C-25~+85°C-10~+70°C(SR)(Z)Capacitors and transistors are represented by thefollowing symbols.SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTSNotes:1. Do not use the part number shown on these draw-ings for ordering. The correct part number is shownin the parts list, and may be slightly different oramended since these drawings were prepared.2. All resistance values are indicated in ohms (K=10 3,M=10 6 ).3. Resistor wattages are 1/4W or 1/6W unless other-wise specified.4. All capacitance values are indicated in μF(P=10 -6 μF).5. All voltages are DC voltages unless otherwise speci-fied.(Top View) (Bottom View)(Bottom View)Electrolytic Capacitor+Transistor or Digital TransistorNPN Transistor PNP TransistorNPN Digital Transistor PNP DigitalTransistor(Top View)(Top View)E C BE C BDigital TransistorCBA Symbols Schematic Diagram SymbolsE C B(Top View)(Top View)E C BE C B
