Tips and information for comfortable use

Computer users may complain of eyestrain and headaches after prolonged use. Users are also at risk of physical injury after long hours of working in front of a computer. Long work periods, bad posture, poor work habits, stress, inadequate working conditions, personal health and other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis or other musculoskeletal disorders. 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.

Finding your comfort zone

Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest, or raising your sitting height to achieve maximum comfort. Observe the following tips:

• 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 istant 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.
• Exercise regularly and maintain a healthy body.

TCO Certified

A third-party certification according to ISO 14024

Say hello to a more sustainable product

IT products are associated with a wide range of sustainability risks throughout their life cycle. Human rights violations are common in the factories. Harmful substances are used both in products and their manufacture. Products can often have a short lifespan because of poor ergonomics, low quality and when they are not able to be repaired or upgraded.

This product is a better choice. It meets all the criteria in TCO Certified, the world’s most comprehensive sustainability certification for IT products. Thank you for making a responsible product choice, that help drive progress towards a more sustainable future!

Criteria in TCO Certified have a life-cycle perspective and balance environmental and social responsibility. Conformity is verified by independent and approved verifiers that specialize in IT products, social responsibility or other sustainability issues. Verification is done both before and after the certificate is issued, covering the entire validity  period. The process also includes ensuring that corrective actions are implemented in all cases of factory non-conformities. And last but not least, to make sure that the certification and independent verification is accurate, both TCO Certified and the verifiers are reviewed regularly.

**SCREEN POSITION ADJUSTMENT**

In order to optimize the best viewing position, you can adjust the tilt of the monitor.

• Attaching the Base
  Note: Remove the monitor and monitor base from its packaging. Carefully place the monitor face-down on a stable surface — use a cloth to avoid scratching the screen.

• Monitor Pivot
  Before rotating the display, lift it to the top position and then push it back to the utmost degree. Rotate clockwise until the monitor stops at 90°.
  

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 AC power cord to the Adapter, 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 driven into “Power Saving” mode by the control signal from the display controller, as indicated by the amber-color power LED.

The power saving states will be kept until a control signal has been detected or the keyboard or mouse is activated. The recovery time from Active OFF state back to ON state 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.
