will fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire
plug, have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat
the safety purpose of the grounded plug.

Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect
the monitor from damage due to power surges.

Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
