Important Safeguard
19. Unplug the power cord before inserting any add-on card or module.
20. Use power cord correctly. There are some important safety requirements.
The power cord is equipped either a 2-prong or a 3-prong grounded plug.
The third prong is an important safety feature; do not defeat the safety
purpose of the third grounded plug. If your outlet does not accommodate
the plug, have a qualified electrician install the correct outlet, or use an
adapter to ground the system product safely.
Do not leave the power cord where people may walk on it or place heavy
objects on top of it.
Do not overload wall outlet and extension cords. Electric power overload
will cause fire or electric shock.
When unplug the power cord, be sure to disconnect it by the plug head,
not by its wire.
Keep the power cord/adapter away from children.
