Monitor care
Always remove the plug from the AC outlet when

the cabinet and control panel.
If very dirty, apply neutral detergent to a dampened soft
cloth, wring it out well and wipe away grime.

from the surface of the LCD panel. (A soft cloth such as
gauze or that used for lens cleaning is suitable.)

-
Never use thinner, benzine, alcohol, glass cleaner,
etc, as this could lead to color change or change in

result in malfunction.
Storage
If the monitor will not be used for a long period of time,
be sure to remove the power plug from the AC outlet.

items for long periods of time as this could lead to color
change or change in shape.
