PICKUP
During repair,carefulley take the following precautions.
The laser diode in the optical pickup block is so
sensitive to static electricity surge current and etc,
that the components are liable to be broken down
or its reliability remarkably deteriorated.
PRECAUTIONS
1.Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with inpedance lower than 10M) on the work-
desk and place the set on the conductive sheet so
that the chassis.
2.Grounding for the test equipment and tools.
Test equipments. and toolings should be grounded
in order that their ground level is the same the
ground of the power source.
(The following precautions are included in the service
parts.) ,
3.Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.
4.Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.
5.Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.
