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

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.

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.
