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.
Important safety notice:
Components identified by A. mark have special characteristics important for safety.
When replacing any of these components, use only manufacturer's specified parts.
