LED INDICATOR 

LED is off when power is off; LED glows green when power is on. The power management feature of the monitor is 
designed for security surveillance applications. When there is no video, the monitor remains ON to be instantly ready 
to display video when the source is changed or if a PC changes state from sleep/standby to active mode.  A floating 

“No Signal” box 

moves slowly 

across the screen 

until video is re-

stored.
