(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 : 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.
Example C541 L452
22U 10UH
TA A2520
• 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
XEDIT→ EDIT PB/XREC →PB/REC
•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
!sont critiques pour la sécurité.
Ne les remplacer que par une pièce portant
le numéro spécifie.
Note : The components identified by mark !or
dotted line with mark !are critical for safety.
Replace only with part number specified.
(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the
measurement points and ground when camera shoots
colorbar chart of pattern box. They are referencevalues
and reference waveforms. *
(VOM of DC 10 MΩinput impedance is used.).
• Voltagevalueschangedependinguponinputimpedance
of VOM used.)
1. Connection
2. Adjust the distance so that the output waveform of Fig.
a and the Fig. b can be obtain.
When indicating parts by reference number, please
include the board name.
