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.
• : 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
(SIDE B) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.

Note:
• 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 1/4 W or less unless otherwise
specifi ed.
• : Internal component.
f
• 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.
no mark : TUNER (FM)
< > : DVD PLAY
* : Impossible to measure
• Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
• Signal path.
