wrists, arms, shoulders, neck or back:
•
•
numbness, or a burning or tingling sensation
aching, soreness or tenderness

distant point.
•
Blink frequently to keep your eyes from drying out.
Display
•
•

point downward when looking at the middle of the display.
Adjust the display brightness and/or contrast to a comfortable level for enhanced
text readability and graphics clarity.
•
•
Eliminate glare and reflections by:
•
placing your display in such a way that the side faces the window or any light
source
viii
•
•
•
•
•
minimizing room light by using drapes, shades or blinds
using a task light
changing the display’s viewing angle
using a glare-reduction filter
using a display visor, such as a piece of cardboard extended from the display’s
top front edge
•
•
Avoid adjusting your display to an awkward viewing angle.
Avoid looking at bright light sources, such as open windows, for extended periods
of time.
Developing good work habits
Develop the following work habits to make your computer use more relaxing and
productive:
•
•
•

Attaching/ Removing the base
Take out the monitor, stand and base from the package, put them on smooth surface.
Align the stand for the back cover portion of the monitor, insert the back cover, ensure that the
monitor and.standconnection is stable, do not shake.
1.
2.
Align base and stand, insert the base to stand, rotating hand screw until tightening, fix the base.
3.
1. Attach the base to the monitor, as illustrated.
2. Ensure that the base is screwed tight onto the monitor stand arm.
2
Screen position adjustment
To optimize the viewving position, you can adjust the monitor tilt by using
both of your hands to hold the edges of the monitor as shown below. The
monitor can be adjusted to 20 degrees up or 5 degrees down.
3
Connecting the Pow er 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.
Pow er 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.

Power saving
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.
