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.
To adjust the threshold 1. Set up your SMART Table for troubleshooting (see page 39).
2. Press the SMART Touch Service task bar button.
The SMART Touch Service window appears.
3. Ensure the keyboard, the mouse and your fingers aren’t on the touch surface, and
then select Options > Settings .
The SMART Touch Options dialog box appears.
4. Press the Restore Defaults button, and then check to see if touch is working
correctly.
5. If touch isn’t working correctly, move the Threshold slider left until the red
markers in the lower-left of the SMART Touch Service window stop flickering.
CAUTION
Do not move any of the other sliders in the SMART Touch Options dialog box
without consulting SMART Technical Support (see page 51).
NOTE
If you move the Threshold slider too far left, you’ll have to press down hard
for the software to detect your touch.
The threshold is set too high. The threshold is set correctly.
