The following are not malfunctions:
• When a bright still image (such as a white cloth) is displayed for a long period, it may appear to be colored. This is due to the
structure of the cathode ray tube and will be deleted when another image is displayed.
• You experience a mild electric shock when you touch the picture tube. This phenomenon is due to a normal buildup of static
electricity on the CRT and is not harmful.
• The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality
appears on the screen as well.
• If two or more monitors are operated next to each other, their images may shake or be distorted. This phenomenon is due to
mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the
power off on any monitor that is not being used .
