THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS
AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each
block.)
• Printed wiring boards.
: parts extracted from the component side.
: parts extracted from the conductor side.
® : Through hole.
: Pattern from the side which enable seeing.
(The other layer's patterns are not indicated.)
• Schematic diagrams.
• All capacitors are in µF unless otherwise noted. pF : µµF 50WV
or less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and 1/4W or less unless otherwise speci-
fied.
¢ : internal component.
: panel designation.
Note : The components identified by mark ! or dotted
line with mark ! are critical for safety.
Replace only with part number specified.

• Voltage and waveforms are dc with respect to ground under no-
signal conditions.
no mark : STOP
• Voltages are taken with a VOM (Input impedance 10MΩ).
Voltage variations may be noted due to normal production tol-
erances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tol-
erances.
• Circled numbers refer to waveforms.
