NOTE  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC  DIAGRAMS
• MAIN and SUB boards are multi-layer printed board.
However, the patterns of intermediate-layer have not been in-
cluded in this diagrams.
Note on Schematic Diagram:
• All capacitors are in 
µ
F unless otherwise noted.  pF: 
µµ

50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in

W or less unless otherwise
specified.
%
: indicates tolerance.
f
: internal component.
C
: panel designation.
A
: B+ Line.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground in
playback mode.
no mark : PLAYBACK
: Impossible to measure
• 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.
• Signal path.
F
: PLAYBACK
*
The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
