NOTES ON SCHEMATIC DIAGRAM
? Resistor:? The indicated voltage in each section is the one measured
To differentiate the units of resistors, such symbol as K andby Digital Multimeter between such a section and the chas-
M are used: the symbol K means 1000 ohm and the symbolsis with no signal given.
M means 1000 kohm and the resistor without any symbol is1. In the tuner section,
ohm-type resistor. Besides, the one with OFusible� is a fuse( ) indicates AM
type.< > indicates FM stereo
? Capacitor:2. In the main section, a tape is being played back.
To indicate the unit of capacitor, a symbol P is used: this3. In the deck section, a tape is being played back.
symbol P means micro-micro-farad and the unit of the( ) indicates the record state.
capacitor without such a symbol is microfarad. As to4. In the power section, a tape is being played back.
electrolytic capacitor, the expression Ocapacitance/withstand5. In the CD section, the CD is stopped.
