DISASSEMBLY
Caution on Disassembly
Follow the below-mentioned notes when disassembling
the unit and reassembling it, to keep it safe and ensure
excellent performance:
1. Take the battery and minidisc out of the unit.
2. When disassembling the machine, be sure to withdraw
the power plug from the socket in advance.
3. When disassemble the parts, remove the nylon band or
wire holder as necessary.
To assemble after repair, be sure to arrange the wires as
they were.
If a screw of different length is fitted to the MD mechanism (the screw of the part to be fitted to the MD
mechanism chassis), it may contact the optical pickup,
resulting in malfunction.
4. When repairing, pay due attention to electrostatic charges
of IC.

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type

• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chassis with no signal given.
• Parts marked with “
”(
) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.
• The wiring diagram and the PWB drawing may be changed
to refect improvements in the design without prior notice.
They may differ a little the unit you have.
