The following symptoms may appear in the hands, wrists, arms, shoulders, neck or back:

numbness, or a burning or tingling sensation
aching, soreness or tenderness
pain, swelling or throbbing
stiffness or tightness
coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort and/or pain related to computer use, consult a physician immediately and inform your company’s health and safety department. The following section provides tips for more comfortable computer use.

refrain from staying too long in one fixed posture
avoid slouching forward and/or leaning backward
stand up and walk around regularly to remove the strain on your leg muscles

Taking care of your vision

Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive room lighting, poorly focused screens, very small typefaces and low-contrast displays could stress your eyes. The following sections provide suggestions on how to reduce eyestrain.

Eyes

Rest your eyes frequently.
Give your eyes regular breaks by looking away from the monitor and focusing on a distant point.
Blink frequently to keep your eyes from drying out.

Display

Keep your display clean.
Keep your head at a higher level than the top edge of the display so your eyes 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
- 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:

Take short breaks regularly and often.
Perform some stretching exercises.
Breathe fresh air as often as possible.

Attaching/ Removing the base

Remove the monitor from the packaging.
Attach the footstand to the monitor, attach the base to the footstand.
Secure the base to the stand by turn the screw clockwise using a screwdriver or a suitable coin.

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 15 degrees up or 5 degrees down.

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-flicker power LED.

Mode	LED light
On	Blue
Power Saving	Amber 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.
