Ω), (
K=1,000, M=1,000,000)
2. CAPACITOR
All capacitors are ceramic 50V capacitor, unless otherwise noted by the following marks.
Unit of capacitance is
µ
F, unless otherwise noted.
3. COIL
Unit of inductance is
µ
H, unless otherwise noted.
4. VOLTAGE MEASUREMENT
Voltage is measured by a digital meter receiving normal signal.
Note: These schematic diagrams are the latest at the time of printing
and are subject to change without notice.
SERVICE NOTES:
This model has section that does not share a common ground with the power supply section. The different sections
