Degauss switch
This monitor is equipped with automatic and manual OSD degaussing. Automatic degaussing is
operativewhen the monitor is cold (after being off for approximately 20 minutes). Therefore, if the monitor is
repositioned while it is warm and discoloration is observed, it is important to remember to turn off the monitor
and let it cool. When powering the monitor back on, it will then degauss automatically and discoloration will
disappear. Manual degaussing is operative by selecting the OSD degauss function.
Caution:
Please allow a minimum of 20 minutes to elapse between uses of the degauss function.
