THIS NOTE IS COMMON FOR PRINTED WIRING

BOARDS AND SCHEMATIC DIAGRAMS.

(In addition to this, the necessary note is printed

in each block.)

For schematic diagrams.

Note:

• 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

specified.

•

: internal component.

• 2 : nonflammable resistor.

• 5 : fusible resistor.

• C : panel designation.

Note:

The components identified by mark 0 or

dotted line with mark 0 are critical for

safety.

Replace only with part number specified.

• U : B+ Line.

• V : B– Line.

• H : adjustment for repair.

• Voltages and waveforms are dc with respect to ground

under no-signal (detuned) conditions.

• 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.

For printed wiring boards.

Note:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

•

: Through hole.

• b : 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 the

(Side B)

pattern face are indicated.

Parts face side: Parts on the parts face side seen from the

(Side A)

parts face are indicated.
