RESTORATION
Image restoration does not work unless the monitor has been in normal operation (Green
power indicator) for at least 30 minutes. See page 12 for detailed information about Image
Restoration.
In order to keep the monitor “on”, you may need to check the PC’s power saving setting.
The monitor may gradually lose its ability to perform this function due to the natural aging
of the picture tube.
A hum Is heard right after the
power is turned on

monitor is automatically degaussed for three seconds.
If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result. A humming noise may be heard, but this is not a
malfunction.
