For schematic diagrams.
Note:
• All capacitors are in µF unless otherwise noted. p : µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

4
W or less unless otherwise
specified.
•%: indicates tolerance.
•
f
: internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
No mark : FM
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
•Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
J : ANALOG INPUT
c : DIGITAL INPUT

E51 : Chilean and Peruvian models
MX : Mexican model
SP : Singapore model
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this necessary note is printed in each
block.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side A) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side B) the parts face are indicated.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
