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.

•

: Internal component.

For Schematic Diagrams.

Note:

• All capacitors are in μF 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

speciﬁ ed.

•

: Internal component.

• 2 : Nonﬂ ammable resistor.

• 5 : Fusible resistor.

• C : Panel designation.

The components identiﬁ ed by mark 0

or dotted line with mark 0 are critical for

safety.

Replace only with part number speciﬁ ed.

Les composants identiﬁ és par une marque

0 sont critiques pour la sécurité.

Ne les remplacer que par une pièce por-

tant le numéro spéciﬁ é.

• A : B+ Line.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.

no mark : POWER ON

• 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.
