•Note For Printed Wiring Boards 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 multi-layer printed board.

However, the patterns of intermediate-layer have not been in- cluded in this diagrams.

•A : B+ Line.

•Total current is measured with MD installed.

•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 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.
