THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
Common Note on Schematic Diagrams:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in 
 and 
1
/
4
 
W or less unless otherwise
specified.
%
: indicates tolerance.
f
: internal component.
C
: panel designation.
A
: B+ Line.
• Power voltage is dc 3V and fed with regulated dc power
supply from external power voltage jack.
• Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : REC
(
) : PB
• Voltages are taken with a VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
E
: PB
a
: REC
• For CSP (chip size package), it is impossible to measure
the voltage and waveforms since the package has a dif-
ferent outline from conventional IC’s.
Common Note on Printed Wiring Boards:
• X
: parts extracted from the component side.
• Y
: parts extracted from the conductor side.
f
: internal component.
: Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
