Therapy mode:
The therapy mode can only be activated by the prosthestist with
the C-Soft adjustment software. Once activated, the joint is locked
in full extension, for example for therapeutic applications for early
mobilization after amputation. If required, the joint can be unlocked
with the remote control (e.g. for sitting down). The hydraulic damping
of the system supports the prosthesis wearer when sitting down or
standing up. The prosthesis can be loaded.
To unlock the knee joint:
Press the remote control button for 2 seconds (the joint emits
2 beep sounds at intervals of one second). One long beep sound
and one vibration signal follow to confirm unlocking. Now the knee
joint is unlocked and can be flexed, e.g. for sitting down (Fig. 1).
The joint remains in stance phase damping until it is brought into
extension again.
As soon as the knee angle during extension is less than 7°, the joint
automatically activates the lock in the flexion direction. This is con-
firmed by 2 long beep sounds and 2 vibration signals (Fig. 2).

onds after unlocking, it automatically locks again for safety reasons.
During this period, the remote control cannot be used.
