You can exclude individual air chambers from the massage by pressing on the respective air chamber along the leg on the panel. A further pressure activates the chamber again.
In this way you can avoid pain-sensitive areas from the massage. For example, if the massage is uncomfortable on the foot, simply deactivate the first chamber by tapping chamber 1 on the panel.
You can also easily deactivate the upper chamber if the leg cuff is a little too long for you. This prevents the top chamber from pushing the cuff out of the correct position.
