Warning:

Unplug the power cord from the power outlet and refer to qualified service

personnel under the following conditions:

• When the power cord is damaged.
• If the LCD display has been dropped or the housing has been damaged.
  ◆ If the LCD display emits smoke or a distinct odor.

Notice for the LCD Display

• In order to maintain the stable luminous performance, it is recommended to use low brightness setting.
• Due to the lifespan of the lamp, it is normal that the brightness quality of the LCD display may decrease with time.
• When static images are displayed for long periods of time, the image may cause an imprint on the LCD display. This is called image retention or burn-in.

◆ To prevent image retention, do any of the following:

• Set the LCD display to turn off after a few minutes of being idle.
• Use a screen saver that has moving graphics or a blank white image.
• Execute the ANTI-BURN-IN function of the LCD display. Refer to "ANTI-BURN-IN" on page 47.
• Switch desktop backgrounds regularly.
• Adjust the LCD display to low brightness settings.
• Turn off the LCD display when the system is not in use.

◆ Things to do when the LCD display shows image retention:

• Turn off the LCD display for extended periods of time. It can be several hours or several days.
• Use a screen saver and run it for extended periods of time.
• Use a black and white image and run it for extended periods of time.

- There are millions of micro transistors inside the LCD display. It is normal for a few transistors to be damaged and to produce spots. This is acceptable and is not considered a failure.

- IMPORTANT: Always activate a moving screen saver program when you leave your display unattended. Always activate a periodic screen refresh application if the unit will display unchanging static content. Uninterrupted display of still or static images over an extended period may cause “burn in”, also known as “after-imaging” or “ghost imaging”, on your screen. This is a well-known phenomenon in LCD panel technology. In most cases, the “burned in” or “after-imaging” or “ghost imaging” will disappear gradually over a period of time after the power has been switched off.

- WARNING: Severe "burn-in" or "after-image" or "ghost image" symptoms will not disappear and cannot be repaired. This is also not covered under the terms of your warranty.

• The front of the display has been specially treated. Wipe the surface gently using only a cleaning cloth or a soft, lint-free cloth.
• If the surface becomes dirty, soak a soft, lint-free cloth in a mild detergent solution. Wring the cloth to remove excess liquid. Wipe the surface of the display to remove dirt. Then use a dry cloth of the same type to dry.
• Do not scratch or hit the surface of the panel with fingers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners.

Cabinet Cleaning Instructions

• If the cabinet becomes dirty, wipe the cabinet with a soft, dry cloth.
• If the cabinet is extremely dirty, soak a lint-free cloth in a mild detergent solution. Wring the cloth to remove as much moisture as possible. Wipe the cabinet. Use another dry cloth to wipe over until the surface is dry.
• Do not allow any water or detergent to come into contact with the surface of the display. If water or moisture gets inside the unit, operating problems, electrical and shock hazards may result.
• Do not scratch or hit the cabinet with fingers or hard objects of any kind.
