If touch isn't working correctly, adjust the threshold (see page 52).

Adjusting the Threshold

If your SMART Table continues to behave erratically after you remodel the
background, the camera threshold may be set too high. This causes the camera to
detect more light than necessary. Adjust the threshold to resolve this problem.
NOTE
You shouldn't need to perform this procedure unless your table is located in an
area with high levels of ambient infrared (IR) light, such as near a window or
under bright incandescent lights.
1. Set up your SMART Table for troubleshooting (see page 50).
