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.

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!
