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 t	he
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.
