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.

•

: 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

(Conductor Side)

from the pattern face are indicated.

Parts face side:

For Schematic Diagrams.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF)

50 V 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.

Note: The components identiﬁ ed by mark 0 or

dotted line with mark 0 are critical for safety.

Replace only with part number speciﬁ ed.

Note: Les composants identiﬁ és par une marque

0 sont critiques pour la sécurité.

Ne les remplacer que par une piéce portant

le numéro spéciﬁ é.

• A : B+ Line.

• Voltages and waveforms are dc with respect to ground

in wireless connection to the bar speaker (SA-CT380/

CT381).

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.
