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 extension 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.  
The socket-outlet shall be installed near the equipment and shall be  
easily accessible  
If you encounter technical problems with the monitor, contact a  
qualified service technician or your retailer.  
iv  
 
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 LCD. 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!
