CAUTION
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK
THE FOLLOWING WHEN YOU POSITION THE MONITOR:
• For optimum performance, allow 20 minutes for warm-up.
• Rest your eyes periodically by focusing on an object at least
20 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 and contrast controls to en-
hance readability.
• Avoid displaying fixed patterns on the monitor for long peri-
ods of time to avoid image persistence (afterimage effects).
• Get regular eye checkups.
• The lamp of backlight contains mercury. Please handle it ap-
propriately in case of disposal.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the
following:
• Use the preset Size and Position controls with standard
signals
• Use the preset Color Setting
• Use non-interlaced signals with a vertical refresh rate between
58-62Hz
• Do not use primary color blue on a dark background, as it is
difficult to see and may produce eye fatigue to insufficient
contrast

dangerous shock hazards or other risks. Refer all servicing to
qualified 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, fire or equipment failure.
• Do not place any heavy objects on the power cord. Damage to
the cord may cause shock or fire.
• 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.
• When operating the LCD4000 monitor with its AC 220-240V
power supply, use a power supply cord that matches the power
supply voltage of the AC power outlet being used. The power
supply cord you use must have been approved by and comply
with the safety standards of your country. (Type H05VV-F 3G 1mm
