2.2 Function
This product features microprocessor-controlled damping of plantar flexion (motion of the foot in
the ankle joint in the direction of the sole of the foot) and dorsiflexion (motion of the foot in the
ankle joint in the direction of the instep).
The microprocessor uses the measurements of an integrated sensor system as a basis to control
a hydraulic unit that influences the damping behaviour of the product.
These sensor data are updated and evaluated 100 times per second. As a result, the behaviour of
the product is adapted to the current motion situation (gait phase) dynamically and in real time.
Thanks to the microprocessor-controlled damping of the plantar flexion and dorsiflexion, the
product can be individually adapted to requirements.
For this purpose, the product is adjusted by qualified personnel using adjustment software.
The product features MyModes for special motion types (e.g. golf ...). These modes have default
values configured by the prosthetist using adjustment software, and can be called up via the
remote control or through a special motion pattern (see Page 57).
If configured by the prosthetist, an additional mode "" can also be selected, locking the ankle
joint of the prosthetic foot in its current position.
In case of a system malfunction, safety mode makes restricted operation possible. Predefined
resistance parameters are configured in the product for this purpose (see Page 63).
Empty battery mode permits safe walking when the battery is drained. Resistance parameters that
are predefined by the product are configured for this purpose (see Page 63).
The microprocessor-controlled hydraulic unit offers the following advantages
• Approximation of the physiological gait pattern
• Stability while standing and walking
• Adaptation of product characteristics to various surfaces, inclines, gait situations, walking
speeds and heel heights
3 Application
3.1 Indications for use
The product is to be used solely for lower limb exoprosthetic fittings.
3.2 Area of application
Area of application according to the MOBIS mobility system:
The product is recommended for mobility grade 2 (restricted outdoor walker),
mobility grade 3 (unrestricted outdoor walker) and mobility grade 4 (unrestricted
m°
outdoor walker with particularly high demands). Approved for a body weight of up
kg
to 100 kg (220 lbs).

3.3 Conditions of use

The product was developed for everyday use and must not be used for unusual activities. These
unusual activities include, for example, sports with excessive impact load (tennis, basketball, run­
ning, ...) or extreme sports (free climbing, paragliding, etc.).
Permissible ambient conditions are described in the technical data (see Page 71).
The product is intended exclusively for use on one patient. Use of the product by another person
is not approved by the manufacturer.

3.4 Service Life

The product is a wear part, which means it is subject to natural wear and tear. The service life
diminishes or increases depending on the individual level of use. Only when the instructions for
use are observed it is possible to achieve the maximal service life, in dependence of the level of
use.
