(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
µ
F unless otherwise noted. pF :

50V 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
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

• 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 (DC10M
Ω
).
• Voltage variations may be noted due to normal production
• Circled numbers refer to waveforms.
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
