If no video signal is input to the monitor, the
"NO INPUT SIGNAL" message appears. After
about 30 seconds, the Power Saving function
automatically puts the monitor into active-off
mode and the indicator lights up orange. Once
the monitor detects horizontal and vertical sync
signals, the monitor automatically resumes
normal operation mode.
