1. Precaution
1.4. Static Electricity Precautions
Many parts of the system are susceptible to static electricity. Using an electrostatic discharge (ESD) device is very important
for the safety of the user and the user's surroundings. Using an ESD device increases the probability of a successful repair
and lowers the expenses for damaged parts.
To prevent static electricity, follow the instructions below.
1) Perform the repair in a location without static electricity.
2) Touch your hands to a metal water pipe or some metal object connected to the ground to discharge any static
Electricity from your body before handling the parts.
3) Touch only the edges of the board, if possible.
4) Do not touch any parts unless absolutely necessary
5) Disassemble the parts on the anti-static-electricity pad.
6) When a board is not installed in the system, package the board with an anti-static-electricity packaging.
