For printed wiring boards:
@ o——— ; indicates a lead wire mounted on the component
side.
e——— : indicates a lead wire mounted on the printed side.
(e) : Through hole.
i : Parts mounted on the conductor side.
: Pattern from the side which enables seeing.
ics > Pattern of the rear side.*
Circled numbers refer to waveforms.
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Conductor Side) pattern face are indicated.

e@ 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. Of a
© All resistors are in ohms, 1/4W (Chip resistors: 1/10W) unless
otherwise noted.
kQ: 10002, MQ: 1000kQ.

50V or less are not indicated except for electrolytics and
tantalums.
@ All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
ES =: nonflammabie resistor.
{0A} : fusible resistor.
(=~) : panel designation.
A : intemal component.
{(-—] : adjustment for repair."

Circled numbers refer to waveforms.*
Voltages are dc between measurement point.*
Readings are taken with a color-bar signal input.*
Readings are taken with a digital multimeter (DC10MQ).*
Voltage variations may be noted due to normal production
tolerances.*
