Use the stand to position the display to your preference. It can be rotated between
15º and 40º from the vertical.
The stand provides stability to the computer; it is not a removable part.
Attention:
1. The computer stand must remain installed at all times to ensure
maximum system stability.
2. Make sure the angle of the computer is at least 15 degrees from the
vertical; otherwise the computer will be unstable and could fall over.
