4-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR WIRING BOARDS AND SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(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
isn’t mounted in this model.
• Chip parts.

(For schematic diagrams)
• All capacitors are in µF unless otherwise noted. pF : µµF.
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.
Example C541 L452
22U 10UH
TA A 2520
(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 MW input impedance is used.).
• Voltage values change depending upon input impedance of VOM
used.) *

• 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 :
The components identified by
mark ! or dotted line with mark

Replace only with part number
specified.
Note :
Les composants identifiés par
