CAUTION:
Immediately unplug your monitor from the wall outlet and refer servicing to qualified service 

personnel under the following conditions:

•  When the power supply cord or plug is damaged.
•  If liquid has been spilled, or objects have fallen into the monitor.
•  If the monitor has been exposed to rain or water.
•  If the monitor has been dropped or the cabinet damaged.
•  If the monitor does not operate normally by following operating instructions.

•  For optimum performance, allow 20 minutes for warm-up.
•  Rest your eyes periodically by focusing on an object at least 5 feet away. Blink often.
•  Position the monitor at a 90° angle to windows and other light sources to minimize glare and 

reflections.

•  Clean the LCD monitor surface with a lint-free, nonabrasive cloth. Avoid using any cleaning 

solution or glass cleaner!

•  Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
•  Avoid displaying fixed patterns on the monitor for long periods of time to avoid image 

persistence (after image effects).

•  Get regular eye checkups.

To realize the maximum ergonomic benefits, we recommend the following:

•  Use the preset Size and Position controls with standard signals.
•  Use the preset Color Setting.
•  Use non-interlaced signals.
•  Do not use primary color blue on a dark background, as it is difficult to see and may produce 

eye fatigue due to insufficient contrast.
