7. Voltage Measurement and Waveform Chart
Note:
- 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.
- Circuit voltage and waveform described herein shall be regarded
as reference information when probing defect point because it
may differ from actual measuring value due to difference of
Measuring instrument and its measuring condition and product
itself.

9. Notes of Schematic Diagram
(All schematic diagrams may be modified at any time with the development of the new
technology)
Note:
- 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.
Caution !
IC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
