9.1.7 Walking down stairs

1) Hold the handrail with one hand.
2) Position the leg with the product on the step so that the foot projects halfway over the
3) Roll the foot over the edge of the step.
4) Place the foot of the contralateral leg on the next step.
5) Place the foot of the prosthesis leg on the next step after that.

9.1.8 Walking down a ramp

Under increased flexion resistance, permit controlled flexion of the knee joint which lowers
the body's centre of gravity.
The swing phase is not triggered even though the knee joint is flexed.

9.1.9 Kneeling

Under increased flexion resistance, permit controlled flexion of the knee joint to gradually
reach the kneeling position. A hard impact of the knee joint on the ground should be avoided
so the electronics are not damaged.
Using the 4X860=* C-Leg protector is recommended for kneeling frequently.

9.2 MyModes

In addition to basic mode (mode 1), MyModes can be activated and configured with the adjustment software. They
can be called up by the patient using the cockpit app, remote control (optional accessory) or motion patterns.
Switching by using motion patterns has to be activated in the adjustment software.
These modes are intended for specific motion patterns or postures (e.g. inline skating, ...). Default settings for
these motion patterns and postures can be called up and individually adapted using the adjustment software.
Settings can also be adjusted by the patient using the cockpit app or remote control (see Page 68).
