Battery Capacity - Otto Bock Genium Patient Information

CAUTION
Non-active safety mode. If the safety mode can no longer be activated, there is the risk that the
patient will fall.
If the 3B1/3B1=ST knee joint can no longer be set to safety mode (e.g. in the event of a short circuit
due to water damage), the patient must actively secure the knee joint with the residual limb musculature
upon heel strike and visit a prosthetist as soon as possible.
CAUTION
Danger when activating safety mode. The damping characteristics of the knee joint change when
a safety mode is activated. In certain situations, this can cause you to fall.
As soon as the sound and vibration signals are emitted simultaneously, stop all activities involving the
leg prosthesis. After approx. 10 seconds in a secure standing position, determine whether stance phase
resistance is active by repeatedly flexing the 3B1/ 3B1=ST knee joint slightly under controlled load.
CAUTION
Safety mode cannot be deactivated. When the knee joint is in safety mode, this most likely indicates
a knee joint defect. Malfunctions may occur in this state. This can cause you to fall.
If the safety mode could not be deactivated by recharging the battery, an error has occurred. Contact
the prosthetist to have the error corrected.

Battery Capacity

During normal operation, the battery charge level is indicated via vibration signals (in addition to the
display on the remote control) (see Section "Charging the 3B1 / 3B1=ST Knee Joint").
Storage and Bleeding Air
To store the knee joint, push the knee head to the flexion stop. Upon putting the knee joint back into use,
hold it vertically with the knee head up and push the knee head to full extension.
During extended non-vertical storage of the 3B1/ 3B1=ST knee joint, air may accumulate in the hydraulics.
This is noticeable through sounds and irregular damping behaviour.
The automatic ventilation mechanism ensures that all functions of the 3B1/ 3B1=ST knee joint are once
again available after approx. 10 - 20 steps.
Service
INFORMATION
This component has been tested according to ISO 10328 standard for three million load cycles.
Depending on the amputee's activity this corresponds to a duration of use of three to five years.
The service life can be individually extended in dependence of the intensity of use by making use of
regular service inspections (see Genium Service Pass 646D534=*).
In the interest of your own safety and in order to maintain operating safety and warranty, a service
inspection is required after 24 months.
This service inspection includes a verification of the sensors and the replacement of worn parts.
For the service inspection, the 3B1/3B1=ST knee joint with installed AXON tube adapter (2R20/2R21),
remote control (4X350) and complete charger (4E60) including power supply (757L16-3) and Genium
Service Card (646D534) must be sent to the authorised Ottobock Service Centre.
Please contact your prosthetist well before the service inspection is due.
