Ergonomic Guidelines

Many experts believe that the extended use of any computer screen has the potential to cause serious injury to your eyes, neck and back. This can be largely avoided by correctly positioning your display.

Viewing angle: Ergonomists recommend that the optimal position of your display should be slightly below eye level. When looking at the display's centre the user should have a downward visual angle of approximately 10°-20° .

Height: As a guide, the height (h) of your display should approximately be as follows:

• Tall Male (Max): 560mm (22")
• Short Male (Min): 368mm (14.5")
• Tall Female (Max): 520mm (20.5")
• Short Female (Min) 356mm (14")

Distance: For visual comfort, a viewing distance (d) between 500mm (20") to 750mm (29.5") is recommended.

Tilt Angle: Angular adjustments to reduce reflection on your monitor should range between 5° forward tilt to 15° backward tilt.

You are now ready to install your Systema Monitor Arms. Please refer to the Installation Instructions Included with these products.
