Recommended Use & Maintenance
Recommended Use
Ergonomics
To realize the maximum ergonomic benefits, we recommend the following:
• For optimum performance of the monitor, allow 20 minutes for warming up. Avoid reproduction of still patterns on the monitor
for long periods of time to avoid image persistence (after image effects).
• 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.
• Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
• Get regular eye checkups.
• Use the preset Size and Position controls with standard input signals.
• Use the preset color settings.
• Use non-interlaced signals.
• Do not view the primary color blue on a dark background. It is difficult to see and may cause eye fatigue due to insufficient
contrast.
Maintenance
Cleaning the LCD Screen
• When the LCD screen is dusty, please gently wipe with a soft cloth.
• Clean the LCD screen surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!
• Please do not rub the LCD screen with a hard or abrasive material.
• Please do not apply pressure to the LCD screen surface.
