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

W or less unless otherwise
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.

• CN401 of XVM-H65D is connected to Connection Box
with a monitor cable.
Power voltage is dc 14.4 V from ACC cord of the Connec-
tion Box and fed with regulated dc power supply.
• CN401 of XVM-H65D is connected to Connection Box
with a monitor cable.
Voltage and waveforms are measured at input the color
bar signal from the Connection Box.
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.

Note:
The components identi-
fied by mark
0
or dotted
line with mark

are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
