THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN

ORDER FOR THIS MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO INPUT SIGNAL.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA)
and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees
(NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is
no video-input signal present. When there is no video input signal this monitor, following a time-out period, will
automatically switch to an OFF mode. This reduces the monitor’s internal power supply consumption. After the
video input signal is restored, full power is restored and the display is automatically redrawn. The appearance is
similar to a “Screen Saver” feature except the display is completely off. The display is restored by pressing a key
on the keyboard, or clicking the mouse.
