****** Page 3 ****** Special notes on LCD monitors The following are normal with the LCD monitor and do not indicate a problem. Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the power switch and then turn it on again to make sure the flicker disappears. You may find slightly uneven brightness on the screen depending on the desktop pattern you use. The LCD screen has 99.99% or more effective pixels. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all the time. Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the power switch for a few hours.

****** Page 16 ****** 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 Power saving LED light Blue Flicker 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. 4
