THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• 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.)
• Indication of transistor.

• SERVO board is multi-layer printed board.
However, the patterns of intermediate-layer have not
been included in this diagrams.
For Schematic Diagrams.
Note:
• All capacitors are in μ F unless otherwise noted. (p: pF) 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
speci fi ed.
•
A
: B+ Line.
• Power voltage is dc 14.4V and fed with regulated dc pow-
er supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : DVD PLAY
*
: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M

).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
