First, place the Free2 on a sturdy and flat surface. Remove the removable wrist pad by pulling it upwards from the sides. Put the click tension which can be found on the underside of the product to the lowest setting.
If this has worked please place the wrist pads securely back onto the product, and adjust the click tension to your desired level.
If this has not worked please continue with the next recommendation below.
Please download the driver for the Free2 which can be found at: http://ergo.contour-design.com/support-and-downloads/drivers
Afterwards, please test if the click will work. If not, try the Free2 at another computer. It may not be a problem with the Free2, but the computer itself.
If the problem still persists, please contact us at for assistance.
