• 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

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.

  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:
