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, in case use at a PC then it should   use the monitor only with 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.   The wall socket shall be installed near the equipment and shall be   easily accessible.   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 LED. 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!   Conventions used in this guide   WARNING: Information to prevent injury to yourself when trying   to complete a task.   CAUTION: Information to prevent damage to the components   when trying to complete a task.   IMPORTANT: Information that you MUST follow to complete a   task.   NOTE: Tips and additional information to aid in completing a   task.   v Where to find more information   Refer to the following sources for additional information and for product and   software updates.   1.   2.   ASUS websites   The ASUS websites worldwide provide updated information on ASUS   hardware and software products.
