THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is
printed in each block.)
for schematic diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
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
specified.
•%: indicates tolerance.
•
f
: internal component.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
•Voltage and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• BD section
no mark : CD
• VIDEO (1/2), (2/2), MAIN (1/4), (2/4), (3/4), (4/4), PANEL,
POWER sections.
no mark : FM
(): CD
[]: TAPE
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
f : AM
E : PB (DECK A)
d : PB (DECK B)
G : REC (DECK B)

• Abbreviation
E3 : 240 V AC area in E model
EA : Saudi Arabia model
MY : Malaysia model
SP : Singapore model
TH : Thai model
for printed wiring boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• x : parts mounted on the conductor side.
• : Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.

Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B) pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
(Side A) parts face are indicated.
