Notes On Schematic Diagram; Type Qf Transistor And Led - Sharp CD-C471 W Service Manual

CD-C471 W
Resistor:
l
To differentiate the units of resistors, such symbol as K and
ohm-type resistor. Besides, the one with " Fusible" is a fuse
Capacitor:
l
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression " capacitance/withstand
voltage" is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type

The indicated voltage in each section is the one measured
l
by Digital Multimeter between such a section and the chas-
sis with no signal given.
1. In the tuner section,
2. In the main section, a tape is being played back.
3. in the deck section, a tape is being played back.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
Parts marked with " A " ( c - - - 7) are important for
l
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.
