Maintaining the Monitor
General Precautions
Make sure the monitor is turned off and the power cable is unplugged from the power outlet.
Never spray or pour any liquid directly onto the screen or case.
Handle the monitor with care, as a darker-colored monitor, if scuffed, may show marks more
clearly than a lighter-colored monitor.
