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.

• 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, Be-
cause 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

SECTION 4
(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the measure-
ment points and ground when camera shoots color bar chart of
pattern box. They are reference values and reference wave-
forms.
(VOM of DC 10 MΩ input impedance is used.).
• Voltage values change depending upon input impedance of VOM
used.)
