16 Schematic Diagram
•
The voltage value and waveforms are the reference voltage of this unit measured by DC electronic voltmeter (high impedance)
and oscilloscope on the basis of chassis. Accordingly, there may arise some error in voltage values and waveforms depending
upon the internal impedance of the tester or the measuring unit.

Importance safety notice:
Components identified by
mark have special characteristics important for safety. Furthermore, special parts which have
purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. When replacing any
of components, be sure to use only manufacturer´s specified parts shown in the parts list.
