THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
a

: Through hole.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side:
Parts on the pattern face side seen from

Note:
• All capacitors are in PF unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in : and 1/4 W or less unless otherwise
specifi ed.
f
•
: internal component.
• C : panel designation.
Note: The components identifi ed by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specifi ed.
• A : B+ Line.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
