Safety information
•
Before setting up the monitor, carefully read all the documentation that came
with the package.
•
•
To prevent fire or shock hazard, never expose the monitor to rain or moisture.
Never try to open the monitor cabinet. The dangerous high voltages inside the
monitor may result in serious physical injury.
•
•
If the power supply is broken, do not try to fix it by yourself. Contact a qualified
service technician or your retailer.
Before using the product, make sure all cables are correctly connected and the
power cables are not damaged. If you detect any damage, contact your dealer
immediately.
•
•
Slots and openings on the back or top of the cabinet are provided for
ventilation. Do not block these slots. Never place this product near or over a
radiator or heat source unless proper ventilation is provided.
The monitor should be operated only from the type of power source indicated
on the label. If you are not sure of the type of power supply to your home,
consult your dealer or local power company.
•
•
•
•
•
•
Use the appropriate power plug which complies with your local power
standard.
Do not overload power strips and extention cords. Overloading can result in
fire or electric shock.
Avoid dust, humidity, and temperature extremes. Do not place the monitor in
any area where it may become wet. Place the monitor on a stable surface.
Unplug the unit during a lightning storm or if it will not be used for a long period
of time. This will protect the monitor from damage due to power surges.
Never push objects or spill liquid of any kind into the slots on the monitor
cabinet.
To ensure satisfactory operation, use the monitor only with UL listed
computers which have appropriate configured receptacles marked between
100-240V AC.
•
If you encounter technical problems with the monitor, contact a qualified
service technician or your retailer.

electronic equipment, and mercury-containing button cell battery) should not
be placed in municipal waste. Please check local regulations for disposal of
electronic products.
v
Care & Cleaning
•
Before you lift or reposition your monitor, it is better to disconnect the cables
and power cord. Follow the correct lifting techniques when positioning the
monitor. When lifting or carrying the monitor, grasp the edges of the monitor.
Do not lift the display by the stand or the cord.
•
•
Cleaning. Turn your monitor off and unplug the power cord. Clean the monitor
surface with a lint-free, non-abrasive cloth. Stubborn stains may be removed
with a cloth dampened with mild cleaner.
Avoid using a cleaner containing alcohol or acetone. Use a cleaner intended
for use with the monitor. Never spray cleaner directly on the screen, as it may
drip inside the monitor and cause an electric shock.
The following symptoms are normal with the monitor:
•
The screen may flicker during the initial use due to the nature of the fluorescent
light. Turn off the Power Switch and turn it on again to make sure that the
flicker disappears.
•
•
You may find slightly uneven brightness on the screen depending on the
desktop pattern you use.
When the same image is displayed for hours, an afterimage of the previous
screen may remain after switching the image. The screen will recover slowly or
you can turn off the Power Switch for hours.
•
When the screen becomes black or flashes, or cannot work anymore, contact
your dealer or service center to fix it. Do not repair the screen by yourself!
