14. (J 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.
15. This schematic diagram may be modified at any time with the development of new
technology.
16. AX indicates that only parts specified by the manufacture be used for safety.
