    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....

13 Replacement Parts List
 
    · 
    Important 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.
Whenreplacing any of these components, be sure to use onlymanufacturers’s specified parts shown in the parts list.
