Refer all servicing to qualifi ed service personnel.
• Do not spill any liquids into the cabinet or use your
monitor near water.
• Do not insert objects of any kind into the cabinet slots, as
they may touch dangerous voltage points, which can be
harmful or fatal or may cause electric shock, fi re or
equipment failure.
• Do not place any heavy objects on the power cord.
Damage to the cord may cause shock or fi re.
• Do not place this product on a sloping or unstable cart,
stand or table, as the monitor may fall, causing serious
damage to the monitor.

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 refl ections.
• 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 fi xed patterns on the monitor for long
periods of time to avoid image persistence (after image
effects).
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomic benefi ts, we recommend
the following:
• Use the preset Size and Position controls with standard
signals.
• Use the preset Color Setting.

• Do not use primary color blue on a dark background, as
it is diffi cult to see and may produce eye fatigue due to
insuffi cient contrast.
