Important safety notice:
Components identified by A mark have special
characteristics important for safety. When replac-
ing any of these components use only manufac-
turer’s specified parts.
Indicated voltage values are the standard values for
the DC electronic circuit tester (high-impedance)
with the ground point taken as standard. Therefore,
there may exist some errors in the voltage values,
depending on the invertal impedance of the DC
circuit tester,
