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.
6 )Because this unit can't be used on its own right,
sur ely mount it on PC(486 or more) and check
operating condition by using a suitable device
d ri v er floopy diskette. Refer to instructions
manual for more information.
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
Place the earthed conductive plate such as
copper plate on the work table.
3)Cautions for clothes
Do not have any clothes touch with Pick-up
because the static electricity in clothes
can remain even after grounding
