Note on Schematic Diagram:
•All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
•All resistors are in Ω and 1/4 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 wa vef orms are dc with respect to ground in
playback mode.
no mark : PLAYBACK

〈〈 〉〉 : USB
∗: Impossible to measure
•V oltages are taken with a V OM (Input impedance 10 MΩ).
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: PLAYBACK
j: REC (ANALOG IN)
l: REC (DIGITAL IN)
F: USB CHECK OUT
•The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
•Abbreviation
FR : French model

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 par ts 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.
*Replacement of IC801 used in this set requires a spe-
cial tool.
