					Connecting the power cord   
					• 
					Check first to make sure that the power cord you use is the correct type   
					required for your area.   
					• 
					The monitor has a universal power supply that allows operation in either   
					100/120 V AC or 220/240 V AC voltage area. No user-adjustment is   
					required.   
					• 
					• 
					• 
					Plug one end of the power cord to the AC inlet, and plug the other end   
					into an AC outlet.   
					For units using 120 V AC:   
					Use a UL-listed cord set, type SVT wire and plug rated 10 A/125 V.   
					For units using 220/240 V AC:   
					Use a cord set consisting of H05VV-F cord and plug rated 10 A/250 V. The   
					cord set should have the appropriate safety approvals for the country in   
					which the equipment will be installed.   
					Power saving   
					The monitor will be switched to "power saving" mode by the control signal   
					from the display controller, as indicated by the amber-colored power LED.   
					Mode   
					On   
					LED light   
					Blue   
					Power saving   
					Amber   
					The power saving mode will be kept until a control signal has been detected or   
					the keyboard or mouse is activated. The recovery time from "power saving"   
					mode back to "on" is around 3 seconds.   
					Display Data Channel (DDC)   
					To make installation easier, so long as your system supports the DDC protocol,   
					the monitor is able to plug-and-play. The DDC is a communication protocol   
					through which the monitor automatically informs the host system about its   
					capabilities; for example, supported resolutions and corresponding timing. The   
					monitor supports the DDC2B standard.
