8. The drive circuit IC voltage and wave farm are not
indicated in side the schematic diagram.
9. Indicated voltage valuse are the standard values for
the unit measured by
De
electron ie circuit tester
(high impedance) with the chassis taken as
standard. Therefore. there may exist some errors
in the voltage values, dependingon the internal im~
pedance of the
De
cirCUit tester.
