: 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

• 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.
Example C541 L452
22U 10UH
TA A 2520
• 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

(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 MW input impedance is used.).
• Voltage values change depending upon input impedance of VOM
used.) *
1. Connection
2. Adjust the distance so that the output waveform of Fig. a and
the Fig. b can be obtain.
