THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and
1
specified.
f
• : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
Note: The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
• H : adjustment for repair.
• A : B+ Line.
• B : B– Line.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
