Handling Static-Sensitive Adapters
Warning: Adapters can be damaged by static electricity discharge.
The adapters are wrapped in antistatic bags to prevent this damage.
Take the following precautions when handling devices sensitive to static
electricity discharge:
1. Hold the device (still in the antistatic bag) in one hand, and with the
other hand, touch the metal on the system unit frame.
