Chapter 1 Safety Instruction
�
Wear an antistatic wrist strap (the other end of wrist strap must
be well grounded) before touching the equipment or holding
a plug-in board, circuit board, Integrated Circuit (IC) chip or
other devices, to prevent human static electricity from damag-
ing sensitive components.
be well grounded) before touching the equipment or holding
a plug-in board, circuit board, Integrated Circuit (IC) chip or
other devices, to prevent human static electricity from damag-
ing sensitive components.
�
A resistor over 1 MΩ should be connected in series on the cable
between the antistatic wrist strap and the grounding point, to
protect the operator against accidental electric shock. Resis-
tance over 1 MΩ is low enough to discharge static voltage.

check. Do not replace the cable of an antistatic wrist strap
with any other cable.
�
Do not contact static-sensitive modules with any object that
easily generates static electricity. For example, friction of pack-
age bag, transfer box and transfer belt made from insulation
plastic may cause static electricity on components. Discharge
of static electricity may damage components when they con-
tact a human body or the ground.

Modules should only contact materials such as antistatic bag.
Keep modules in antistatic bags during storage and transporta-
tion.

Do not place the module near a strong DC magnetic field, such
as the cathode-ray tube of a monitor. Keep the module at least
10 cm away.
