7. Connection of the Speaker Wiring
8. Block Diagram
9. 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.
- Cover the parts boxes made of plastics with aluminium foil.
