CHARTS AND DIAGRAMS

NOTES OF SCHEMATIC DIAGRAM
Safety precautions The Components identified by the symbol are
critical for safety. For continued safety, replace safety critical components only with manufacturer's recom­mended parts.
1. Units of components on the schematic diagram
Unless otherwise specified.
1) All resistance values are in ohm, 1/6 W, 1/8 W (refer to parts list). Chip resistors are 1/16 W.
K or k: k
2) All capacitance values are in µF, (P: PF).
3) All inductance values are in µH, (m: mH).
4) All diodes are 1SS133, MA165 or 1N4148M (refer to parts list).
2. Indications of control voltage
