8.1.4 Sitting

INFORMATION
While sitting, the knee joint switches to energy saving mode. This energy saving mode is activ­
ated regardless of whether the sitting function is enabled in the adjustment software or not.
If the patient is in a sitting position for more than two seconds (i.e. the thigh is
close to horizontal and there is no load on the leg), the knee joint switches the
resistance to a minimum in the extension direction.
If the sitting function is activated in the adjustment software and switched on
via the cockpit app or remote control (optional accessory) (see Page 59), res­
istance is also reduced in the flexion direction.
