[—_]Indicated
voltage
values
are
the
standard
values
for
the unit
measured by the DC electronic circuit tester (high impedance) with the
chassis taken as standard.
Therefore, there may exist some errors in the
voltage values, depending on the internal impedance of the DC circuit
tester.
This schematic diagram may be modified
at any time with the develo-
pment of new technology.
