1.Gen eral Items

1)Be careful not to have eyes or a part of body touch with laser diode when servicing because this product uses laser diode.

2)Do not disassemble Pick-up when servicing. If the laser diode is damaged, replace the entire Mechanism.

3 )Keep away from TV or other electrical appliances

in other not to get influenced by them during servicing.

5) When you insert a disk into disk drive, be sure to load it correctly.

7 )This unit consists of many parts whose features

can affect on safety and importance indicated are specially given in circuit diagr am and part li s t o f crucial parts. Be certain to use the parts with same specifications when replacing these parts.

2. Earthing when handling P ick-up

- Because the laser diode in optical Pick-up Ass'y is subj ect to get out of order due to p o tent i a l difference generated by static electricity charged in clothes or bodies, observe the following earthing items before servicing.

1) Earthing the static electricity in the body

Be sure to wear a grounding strap with one

side earthed around your wrist.

2) Earthing the Work Table
