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 

µ

F unless otherwise noted. pF : 

µµ

F.

50 V or less are not indicated except for electrolytics and
tantalums.

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

• 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

• 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

• Circled numbers refer to waveforms.
• Readings are taken with a color-bar signal input.
• Voltage are dc between ground and measurement points.
• Readings are taken with a digital multimeter (DC 10 M
