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.
Recommended Use
CAUTION:
• 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.
• The device can be physically fixed to the floor with screws to keep it standing still
and avoid it falling over.
Ergonomics
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.
