Safety
CAUTION
Disconnecting/establishing the connection during the adjustment process with the adjustment software
Falling due to unexpected behaviour of the product.
► When wearing the product, the patient must not remain unattended during the configuration process while
connected to the adjustment software.
► Observe the maximum range of the Bluetooth connection.
► During the data transfer (PC to product), the patient must stand or sit without moving.
► If the connection fails while making adjustments, the prosthetist must immediately warn and secure the
patient.If the connection fails while making adjustments, the prosthetist must immediately warn and secure the
patient.
► The connection to the product must always be disconnected after adjustments have been completed.
CAUTION
Insufficient insertion depth of the tube adapter
Falling due to breakage of load-bearing components.
► Insert the tube adapter at least 40mm to ensure operational safety.
The patient must be seated for length adjustments.
CAUTION
Operator errors during the adjustment process with the adjustment software
Falling due to unexpected behaviour of the product.
► Participation in an Ottobock product training course is mandatory prior to using the product. Additional
product training courses may become necessary to qualify for software updates.
► Correctly entering the foot size, the prosthesis dimensions and the body weight are important criteria for the
quality of the fitting. If the values are too high, the prosthesis may not switch to the swing phase. If the values
are too low, the prosthesis may trigger the swing phase at the wrong time.
► Always enter the weight in the specified unit.
► Ensure that the required dimensions are selected and entered correctly.
► If the patient uses walking aids (e.g. crutches or walking canes) during the adjustment process, readjustment
is required as soon as the patient stops using these walking aids.
CAUTION
Safety mode flexion resistance set too low
Falling due to unexpected product behaviour as the result of switching into safety mode.
► Safety mode flexion resistance should be configured so that it is possible to stand safely without the knee joint
buckling.
CAUTION
Using the product without calibration
Falling due to unexpected product behaviour as the result of the swing phase being initiated too early/too late.
► Use the adjustment software to carry out calibration at the beginning of static alignment optimisation and at
the end of dynamic alignment optimisation.
