which enables seeing.
'© gem : Patter of the rear side.
Circled numbers refer to waveforms.
(B) or (F), etc. of capacitors indicate the temperature
characteristics.
* @ : Through hole.
Caution:
Patter face side:
Parts on the pattern face side seen from
(Conductor Side)
the pattern face are indicated.
Parts face side:
Parts on the parts face side seen from the
(Component side) _ pattern face are indicated.
« For schematic diagrams.
* Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minuts side of tantalum capacitor,
because it is damaged by the heat.
* Allresistors are in ohms, 1/4W unless otherwise noted.
Chip resistor are 1/10W unless otherwise noted.
