W or less unless otherwise
specified.
% : indicates tolerance.
C : panel designation.
A : B+ Line.
Total current is measured with MD installed.
Power voltage is dc 3 V and fed with regulated dc power
supply from DC IN 3 V jack (J601).
Voltages and waveforms are dc with respect to ground in
playback mode.

: 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.
Circled numbers refer to waveforms.

The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
6-4. NOTE FOR PRINTED WIRING BOARD AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
X : parts extracted from the component side.
Y : parts extracted from the conductor side.
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
MAIN board is four-layer printed board.
However, the patterns of layers 2 and 3 have not been
included in this diagrams.
