Colour system
This is a characteristic of liquid crystal panels and is not a
problem. The liquid crystal panel is built with very high precision
technology giving you fine picture details. Occasionally, a few
non-active pixels may appear on the screen as a fixed point of
blue, green, or red.
Please note this does not affect the performance of your LCD.
• Use eyeglass cleaner to remove stubborn dirt from the LCD.
• Never use alcohol, paint thinner or benzine to clean this unit.
• Before using chemically treated cloth, read the instructions that came with the
cloth carefully.
• Do not wipe the LCD with water.

Maintenance
To clean this unit, wipe with a soft, dry cloth.
If the surfaces are extremely dirty, use a soft cloth dipped in soap-and-water solution
or a weak detergent solution.
Wipe the cabinet with a soft cloth.
If the cabinet is heavily soiled, wipe with a well-wrung soft cloth dipped in kitchen cleanser (neutral) diluted with water.
CAUTION:
If water or similar substances get inside the monitor via the liquid crystal panel surface, a malfunction may result.
