NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000kohm and theresistor without any symbol is
ohm-type resistor. Besides, the one with "Fusible" is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitorwithoutsuch a symbol is microfarad. As toelectro-
lytic capacitor, the expression "capacitance/withstand volt-
age" is used.
(CH), (TH), (RH),
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
