					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.   
					This symbol of the crossed out wheeled bin indicates that the product (electrical,   
					electronic equipment, and mercury-containing button cell battery) should not   
					be placed in municipal waste. Please check local regulations for disposal of   
					electronic products.

					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!
