Earthing cautions at handling Pick-up
- Because the laser diode in optical Pick-up is subject
to get out of order due to the potential difference
occurring by electricity load charged in clothes or
bodies, observe the following earthing items at
handling.
1)Body earthing(hand) : Be sure to wear a wrist strip
with one side earthed.(Impedance : Below 104).
It removes the electricity formed in body.
2) Work table earthing : Put the earthed conductive
plate(Impedance : Below 104) such as copper plate
on work table.
3)Cautions for clothes : Do not have any clothes
touch with Pick-up because the electricity formed in
clothes is destroyed easily.
Cautions at Service
1. General Items
1) Be careful not to have your eyes or a part of body
touch with laser diode at repair because this
product uses laser diode.
2) Do not disassemble Pick-up at repair. If the laser
diode is bad, replace the entire Pick-up.
3) Keep away from TV or other electrical units at
repair to prevent influence from surrounding units.
4) If you replace the parts during repair, be sure to
unplug the power cable before replacement.
5) If you insert a disc into the drive, be sure to load it
correctly.
6)Because this unit can't be used by itself, surely
mount it on PC (486 DMA support) and check the
operations in use of private device driver floppy
diskette. Refer to Instruction manual.
7)This unit has many parts with features related to
safety and especially, for essential parts, the
importance is indicated on circuit diagram and
part list.
Be certain to use the parts with same specifications
at replacing these parts.
