(For printed wiring boards)

• b: Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

• Through hole is omitted.

• Circled numbers refer to waveforms.

• There are few cases that the part printed on diagram

(For schematic diagrams)

• All capacitors are in µF unless otherwise noted. pF : µ

µF . 50V or less are not indicated except for electrolytics

and tantalums.

• Chip resistors are 1/10W unless otherwise noted.

kΩ=1000Ω, MΩ=1000kΩ.

• Caution when replacing chip parts.

New parts must be attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, Because it is damaged by the heat.

• Some chip part will be indicated as follows.

• Constants of resistors, capacitors, ICs and etc with XX

indicate that they are not used. In such cases, the unused circuits may be indicated.

• Parts with ★ differ according to the model/destination.

Refer to the mount table for each function.

• All variable and adjustable resistors have characteristic

curve B, unless otherwise noted.

• Signal name

• 2: non flammable resistor

• 1: fusible resistor

• C: panel designation

• A: B+ Line *

• B: B– Line *

• J : IN/OUT direction of (+,–) B LINE. *

• C: adjustment for repair. *

• Circled numbers refer to waveforms. *

* Indicated by the color red.

Note : Les composants identifiés par une marque

(Measuring conditions voltage and waveform)

• Voltages and waveforms are measured between the measurement points and ground when camera shoots color bar chart of pattern box. They are reference values and reference waveforms. * (VOM of DC 10 MΩ input impedance is used.).

• Voltage values change depending upon input impedance of VOM used.)
