(All schematic diagrams may be modified at any time with the development of new technology.)
Notes:
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 waveformsdepending upon the internal impedance of the tester or the measuring unit.

Importance safety notice:
Components identifed 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 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.
Cover the parts boxes made of plastics with aluminium foil.
Put a conductive mat on the work table.
Ground the soldering iron.
Do not touch the pins of IC, LSI or VLSI with fingers directly.
