Computer stand

The HP TouchSmart 9100 Business PC is shipped with the computer stand collapsed against the back
of the computer. To assure that the computer is in a stable position on your desktop, pull the computer
stand open until it snaps into place. Then, if you want to change the angle of the HP TouchSmart 9100,
hold each side of the computer, and tilt it (the monitor moves forward; the stand stays in place) to an
angle of between 5 degrees and 40 degrees from the vertical.

CAUTION:

The computer stand stays in place as you increase the angle; the computer moves

forward. Take care that the computer screen does not move off the table.

CAUTION:

Make sure the angle of the computer is at least 5 degrees from the vertical; otherwise the

computer will be unstable and could fall over.
