NOTE:
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 horizon-
tal and vertical sync signals, the monitor automatically resumes normal operation mode.
