POWER SAVING FUNCTION

This monitor is equipped with a power saving function. It goes
into power-saving mode if either of the following conditions
exist:
If either the horizontal sync or vertical sync are not present,
the monitor goes into suspend mode. Suspend mode means
that the power-saving level is substantial, yet the monitor
recovers relatively fast when you press a key or touch the
mouse.
If both horizontal sync and vertical sync are not present, the
monitor goes into active-off mode. Active-off mode means
that the power-saving level is almost at the level of being
shut off, and the monitor takes several seconds to recover
when you press a key or touch the mouse.

The Power Saving function automatically
NOTE:
places the monitor into active-off state if
you turn on the power switch and leave the
rest of the system off. However, once the
monitor can sense the horizontal and verti-

mal operation state.
