POWER SAVING FUNCTION
This monitor has three Power Saving modes. By sensing the absence of a video signal from the computer, it reduces power consumption as follows:
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 horizontal and vertical sync signals, the monitor automatically resumes normal operation mode.
Required Recovery Time
State 1 Normal Operation 2 Standby (1st mode) 3 Suspend (2nd mode) 4 Active-off (3rd mode) 5 Power-off 6 Failure modes

SELF DIAGNOSIS FUNCTION When a failure occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the lamp will identify the first of the problem areas.
