• Voltages are taken with a VOM (Input impedance 10 M ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.

Note on Printed Wiring Board:
•
X
: parts extracted from the component side.
•
: parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Caution:

Parts on the pattern face side seen from
the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.
Note: The components identifi ed by mark

or
dotted line with mark
0
are critical for safety.
Replace only with part number specifi ed.
