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 mecha-

nism (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.
