PRECAUTIONS

l.Ground for the work-desk. 3.Grounding for the human body.
Place a conductive sheet such 3 a sheet of copper Be sure to put on a wrist-snap for grounding whose

desk and place the set on the conductive sheet so
that the chassis.

I2.Grounding for the test equipment and tools.

Test equipments and toolings should be grounded

in order that their ground level is the same the

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 I
have the tip of the iron well-grounded.
5.Do not check the laser diode terminals with the

ground of the power source. probe of a circuit tester or oscilloscope.
