Safety Precautions, Maintenance & Recommended Use
FOR OPTIMUM PERFORMANCE, PLEASE NOTE
THE FOLLOWING WHEN SETTING UP AND USING
THE LCD COLOR MONITOR:
• DO NOT REMOVE MONITOR BACK COVER. There are
no user serviceable parts inside and opening or removing
covers may expose you to dangerous shock hazards or
other risks.
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.
• When operating the LCD monitor with an AC 100-120V
power supply in North America, use a power supply cord
provided with this monitor.
• When operating the LCD monitor with an AC 220-240V
power supply in Europe, use a power supply cord
provided with this monitor.
• In UK, use a BS-approved power cord with molded plug
having a black (10A) fuse installed for use with this
monitor.
If a power cord is not supplied with this monitor, please
contact your supplier.
• When operating the LCD monitor with a 220-240V AC
power supply in Australia, use the power cord provided
with this monitor.
If a power cord is not supplied with this monitor, please
contact your supplier.
• For all othercase, use a power cord that matches the AC
voltage of the power outlet and has been approved by
and complies with the safety standard of your particular
country.
• Do not place any objects onto the monitor and do not use
the monitor outdoors.
• The inside of the fl uorescent tube located within the LCD
monitor contains mercury. Please follow the laws or rules
of your municipality to dispose of the tube properly.
• Do not bend power cord.
• Do not use monitor in high temperature, humid, dusty, or
oily areas.
• If monitor or glass is broken, do not come in contact with
the liquid crystal and handle with care.
• Allow adequate ventilation around the monitor, so that
heat can properly dissipate. Do not block ventilated
openings or place the monitor near a radiator or other
heat sources.
Do not put anything on top of the monitor.
• The power cable connector is the primary means of
detaching the system from the power supply. The monitor
should be installed close to a power outlet, which is easily
accessible.
• Handle with care when transporting. Save packaging for
transporting.
• Please clean the holes of back cabinet to reject dirt and
dust at least once a year because of set reliability.
• If using the cooling fan continuously, it’s recommended to
wipe holes a minimum of once a month.
• When installing the remote control batteries;
- Align the batteries according to the (+) and (-)
indications inside the case.
- Align the (-) indication of the battery fi rst inside the
case.
CAUTION:
Immediately unplug your monitor from the wall outlet and refer
servicing to qualifi ed service personnel under the following
conditions:

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 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.
• Use non-interlaced signals.
• 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.
