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
3.Grounding for the human body.
Be sure to put on a wnist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
that the chassis. synthetic fiber clothes, or air is dry.
2.Grounding for the test equipment and tools. 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.
Test equipments and toolings should be grounded
in order that their ground level is the same the
ground of the power source.
