Application
INFORMATION
Before using the 3B1/3B1=ST knee joint, please read these instructions for use thoroughly! Please
follow your prosthetist's directions and observe the safety instructions carefully.
The 3B1 / 3B1=ST knee joint is intended exclusively for exoprosthetic ttings of the lower extremities.
Conditions of Use
The 3B1 / 3B1=ST knee joint was developed for activities of daily life but not for extreme sports such as
free climbing, skydiving, paragliding, etc. Please see the Technical Information section for the permissible
environmental conditions. The 3B1 / 3B1=ST knee joint is intended exclusively for ttings of amputees or
dysmelia patients. Use of the product by other persons is not approved by the manufacturer.
Function
The 3B1 / 3B1=ST knee joint is an electronic knee joint system with hydraulic stance and swing phase
control. It is controlled by a microprocessor-based hydraulic system that dynamically adapts the system
in real time. The control mechanism works in conjunction with a sensor system. The sensors collect
measurements every 0.01 seconds (corresponds to 100 Hz). Through the evaluation of the measure-
ments, the 3B1 / 3B1=ST knee joint recognises which phase of gait the user is in.

• Loss of functionality due to structural failure.
This can cause you to fall and / or result in skin irritation.
For the purpose of transportation, use the packaging in which the knee joint was delivered.
CAUTION
Magnetic interference. The knee joint can malfunction when near high-tension power lines, transmitters,
transformers, computer tomography equipment or other sources of strong electromagnetic radiation
(such as security systems for goods in department stores). This can cause you to fall.
Avoid proximity to strong sources of magnetic and electric interference (e.g. transformer stations,
transmitters).

28 | Ottobock Genium - Bionic Prosthetic System
CAUTION
Thermal overloading. Extended exposure to high temperatures can lead to defects and result in mal-
functions of the knee joint with a loss of functionality due to structural failure. This can cause you to fall.
Avoid areas with extreme temperatures (see the "Technical Information" section).
CAUTION
Mechanical overloading. Exterior mechanical impacts or stress such as shocks and vibrations can
lead to:
• Short circuits in the electronics and battery, resulting in malfunction of the knee joint.
• Defects of the battery and the hydraulic unit, resulting in leaks.
• Loss of functionality due to structural failure.
This can cause you to fall and / or result in skin irritation. Do not expose system components to me-
chanical vibrations or shocks.
CAUTION
Penetration of dirt and humidity. Penetration of dirt and humidity into the system components can
lead to:
• Short circuits in the electronics and battery, resulting in malfunctions of the knee joint.
•
Hydraulic unit defects with an associated leakage of uid or a loss of functionality due to structural
failure. This may cause the patient to fall and/or result in skin irritation.
• Ensure that neither solid particles nor liquids can penetrate the system components.
•
The knee joint and the AXON tube adapter are protected against splashed water from all directions.
• The knee joint and the AXON tube adapter are not protected against submersion, jets of water
and steam.
• If water has penetrated electronic system components, remove the cosmetic cover and allow the
components to dry. The knee joint must then be sent to an authorised Ottobock Service Centre
for inspection. Your prosthetist is the contact person.
•
If the knee joint comes into contact with salt water, clean it immediately with a cloth moistened
with freshwater and let it dry. The knee joint must then be sent to an authorised Ottobock Service
Centre for inspection. Your prosthetist is the contact person.
CAUTION
Improper use of the knee joint. Any kind of overloading or excessive strain as well as improper use
can lead to:
• Defects and resulting malfunctions of the knee joint
• Loss of functionality due to structural failure
• Defects of the battery and the hydraulic unit, resulting in leaks
This can cause you to fall and / or result in skin irritation.
The 3B1/ 3B1=ST knee joint was developed for everyday use and must not be used for unusual
activities such as extreme sports (free climbing, paragliding, etc.).
Careful handling of the prosthesis and its components not only increases their service life but, above
all, ensures your personal safety. Should the prosthesis be subjected to extreme strain (e.g. by falling
or similar), it must be inspected for possible damage by a prosthetist immediately. If necessary, the
responsible prosthetist will pass the prosthesis on to Ottobock Service.

Ottobock | 29Genium - Bionic Prosthetic System
CAUTION
Overheating of the hydraulic unit. Extended, continuous use (e.g. lengthy downhill walks) can lead to:
• Overheating of the hydraulic unit resulting in malfunction of the knee joint
• Defects of the hydraulic unit resulting in leakage of liquid
This can cause you to fall and / or result in skin irritation. Touching overheated components can also
cause burns.
Please take note of pulsating vibration signals. They indicate the risk of overheating. As soon as
these pulsating vibrations begin, stop all activities and allow the hydraulic unit to cool down. You may
resume your activities once the pulsating vibration signals stop.
If activities are continued despite the pulsating vibration signals, there is the risk of overheating the
hydraulic element and, in extreme cases, of damage to the 3B1/ 3B1=ST knee joint. The knee joint-
should then be sent to an authorised Ottobock Service Centre for inspection. Please contact your
prosthetist with any service questions.
CAUTION
Risk of falling when walking down stairs.
•
When walking down stairs, the banister or handrail should always be used and the prosthetic
foot should be placed on the step so that the heel (max. centre of the foot) is close to the edge of
the step to facilitate rollover.
•
If the audible signal sounds, stop descending immediately and check whether stance phase control
is active (see Section „Important Information for Users“).
•
Observe the vibration signals and audible warning signals (beeps) of the 3B1/ 3B1=ST knee joint.
• Special caution is required when walking down stairs while carrying children.
CAUTION
Improper switching between MyModes. Incorrectly switching from MyModes into basic modeor
vice versa results in a risk of falling (see the section MyModeSwitching with the Remote Control)!
•
After switching to one of the MyModes, check the functions since you may have accidentally
activated a different MyMode than you intended (see the section „MyMode Switching without the
Remote Control“ and the section „MyMode Switching with the Remote Control“)
• Ensure that you switch back to basic mode once your activities in the MyMode have ended.
CAUTION
MyMode Switching with the Remote Control. You can use the Remote Control to initiate various
actions which cause the damping behaviour of the knee joint to change. In certain situations, this
can cause you to fall.
If an unintended action was accidentally initiated using the Remote Control (feedback in the form of
a vibration or audible signal), take your weight off the 3B1/ 3B1=ST knee joint and switch back to
the intended mode.
CAUTION
Consequences of product deterioration. Wear and tear on system components can lead to malfunc-
tion of the knee joint. This can cause you to fall.
For your own safety, comply with the specied service and inspection intervals (maintaining opera-
tional safety and protecting the warranty). Please contact your prosthetist with any service questions.

WARNING
Risk of accidents when operating a motor vehicle. The ability of leg prosthesis wearers to operate
a motor vehicle is determined on a case-by-case basis. Criteria include the type of tting (amputation
height, unilateral or bilateral, residual limb conditions, design of the prosthesis) and the individual
abilities of the leg prosthesis wearer. Ensure you observe the applicable national laws for the opera
tion of motor vehicles and have your driving ability examined and certied by an authorised agency
for insurance purposes. In general, Ottobock recommends that vehicles should be professionally
retrotted to meet each user’s individual needs (e. g. automatic transmission).
Risk-free driving must be ensured even when the leg prosthesis is not functioning.
CAUTION
Malfunction of the knee joint. Malfunctions of the knee joint can cause you to fall.
Observe the vibration signals and audible warnings (beeps) of the 3B1/ 3B1=ST knee joint.
CAUTION
Non-active safety mode. If safety mode can no longer be activated, there is a risk of falling. If the
3B1 / 3B1=ST knee joint is no longer able to select safety mode (e.g. in case of short circuit caused
by water penetration), the knee joint may have to be actively secured upon heel impact using the
residual limb musculature until reaching a prosthetist or replacing the prosthesis. In this case, the
prosthetist must be contacted promptly.
CAUTION
Risk of pinching in the exion range area of the joint. Keep ngers / body parts away from this
area when exing the joint.
INFORMATION
These products may not be disposed of with household waste in some jurisdictions. Disposal
that is not in accordance with the regulations of your country may have a detrimental impact
on health and the environment. Please observe the information provided by the responsible
authorities in your country regarding return and collection processes.
Charging the 3B1/ 3B1=ST Knee Joint
INFORMATION
Charging the battery is only possible at temperatures over 0 °C.
Fully charging the battery in the knee joint takes approx. 6 - 8 hours. The better the connection between
the charger and receiver on the knee joint (not interrupted e.g. by a sock), the shorter the charging time.
1. Connect the power cord to the charger with the correct polarity (Figure 1).
12a 2b

Ottobock | 31Genium - Bionic Prosthetic System
2.
Start the inductive charging process by connecting the charger to the receiver on the back of the
knee joint. The charger is held in place by a magnet (Figure 2a / 2b). Verify the battery capacity us-
ing the LEDs on the side (Figure 3) and the charging process based on the colour of the illuminated
ring (Figure 2b) (see tables below).
3
3. End the inductive charging process by disconnecting the charger from the
receiver. The 3B1/3B1=ST knee joint performs a self-test and is then ready
for operation, provided it is connected to the AXON Tube Adapter. This is
indicated by a single vibration signal and beep. If this is not the case, an error
has occurred. In that case please send the knee joint to your prosthetist or
an authorised Ottobock Service Centre.
INFORMATION
After disconnecting the charger the knee joint will conduct a self test. Be sure not to move the knee
joint during this brief self test, since it can cause an error. If you encounter this error, the problem can
be corrected by reconnecting and then disconnecting the charger.
INFORMATION
Charging is not possible if the distance between the transmitter and receiver is greater than 1.5
mm. However, charging should proceed normally if, for example, a sock or Superskin is between the
transmitter and receiver of the charger (also see the Charging Process table).

5x vibration 10 % approx. 6 hours
10x vibration and beeping 5 % 0 hours
INFORMATION
When the knee joint is fully charged (all 5 LEDs at the side light up (Fig. 3)), the maximum period of
use for the knee joint before the next charging process is up to 5 days, depending on patient activity.
However, we recommend charging the knee joint every night.
Sitting function
When a sitting position is maintained for more than two seconds (i.e. the thigh is close to horizontal and
there is no load on the leg), the 3B1/3B1=ST Knee Joint switches the resistance to a minimum in both
the exion and extension directions. The sitting function can be activated by the prosthetist by using the
X-Soft adjustment software.
INFORMATION
While sitting, the knee joint switches to an energy-saving mode. This energy-saving mode is activated
regardless of whether the Sitting function has been enabled or not.
Intuitive Stance function
The Intuitive Stance function automatically recognises any situation that puts strain on the prosthesis in
the exion direction but where exion is not permitted. Examples where this is the case include standing
on uneven or sloping surfaces. The joint is always locked in the exion direction when the prosthetic leg
is not fully extended, under some amount of load and at rest.
When the load is taken off the leg or upon forward or backward rollover, the level of resistance is
immediately reduced to stance phase resistance again. The knee joint is not locked when the above
conditions are met and a sitting position is assumed (for example while driving). The Intuitive Stance
function can be activated by the prosthetist by using the X-Soft conguration software.

Ottobock | 33Genium - Bionic Prosthetic System
Stairs and Obstacles function
Negotiating stairs step-over-step:
Although the 3B1/ 3B1=ST is a passive knee joint, which means it cannot actively initiate movements,
negotiating stairs step-over-step is possible.
In order to do so, the prosthetic foot has to be placed on the next higher step rst with the knee exed.
Then the hip is extended, which also extends the knee. This requires a sufciently secure hold in the
socket and a certain level of residual limb strength. During physiological stair climbing, knee exion is
accomplished by actively raising the lower part of the leg. With 3B1/3B1=ST knee joint, knee exion
can be achieved via the mass inertia of the lower part of the leg. Immediately after lifting the extended
leg off the oor, simultaneously extend the hip briey and then abruptly ex it. This whip action exes
the knee. The 3B1/3B1=ST knee joint recognises this movement sequence and sets exion resistance
to minimum. Without activation of this mode - i.e. with stance phase resistance - knee exion would be
limited and unpleasant pressure would be felt on the residual limb. The movement pattern is very similar
to the physiological process if the toes extend below the next higher step at the beginning of the cycle.
Here, too, the heel has to be pulled back rst. Practice the “toes under the step” movement pattern with
the sound side and with the prosthesis; then the complete movement pattern is intuitive and easy to learn.
When sufcient knee exion has been achieved, the 3B1/3B1=ST Knee Joint increases extension resist-
ance so that there is enough time to position the foot on the next step before the knee joint is extended
again. The supporting area for the foot on the step has to be sufcient so that the heel does not extend
back too far over the edge. With too little support area, the lower leg would extend too early and position
the leg too far backwards. In this phase, the 3B1/3B1=ST Knee Joint has already maximised the exion
resistance (that is, further exion is blocked). The knee joint can no longer be exed but only extended.
This ensures that the leg does not buckle if the hip strength is not sufcient for the extending motion.
Support yourself with your hand on the contralateral side. A smooth wall is also sufcient for this purpose.
This lateral support is intended to prevent the residual limb from twisting in the socket. Twisting can lead to
unpleasant surface tension between the skin and the socket. Lateral support also improves your balance.
When the knee joint is fully extended, the initial position has been reached. You can climb the next step
or continue walking normally.
Crossing obstacles:
The stairs and obstacles function can be used to cross obstacles. Instead of achieving the required
ground clearance of the prosthetic foot through lateral abduction of the extended leg, the whip action
described above can be used. This is also possible from the walking motion.
Take the weight off the prosthetic leg when the knee joint is extended and then perform the whip motion,
which switches the 3B1/3B1=ST Knee Joint to the stair and obstacle function. This delays the extension
movement, giving enough time and ground clearance to step over an obstacle.

34 | Ottobock Genium - Bionic Prosthetic System
The prosthetic leg will not be fully extended upon heel impact. An active knee joint would be required to
achieve this. Since the knee joint is locked in the exion direction during this phase, putting weight on it
does not pose a hazard. You can then resume walking normally. The stairs and obstacles function can
be activated by the prosthetist using the X-Soft conguration software.
Optimized Physiological Gait (OPG) function
OPG minimizes the Genium user’s prosthetic deviations and promotes a more biomechanically cor-
rect gait pattern. There are no initiation or exit strategies that apply to OPG - it simply happens during
the course of normal walking. Selection of this function enables the following features: (1) PreFlex (2)
Adaptive Yielding Control (3) Dynamic Stability Control (DSC) (4) Stance Release on Ramps, and (5)
Adaptive Swing Phase Control. Adaptive Swing Phase Control and DSC are enabled even if OPG is
not selected on the functions tab.
OPG FEATURES
(1) PreFlex
PreFlex ensures the knee is in four degrees of exion at the end of swing phase in preparation for load-
ing response. PreFlex allows users to walk with natural stance exion independent of gait speed. The
prosthetic foot will also reach foot at more quickly to promote stability especially on uneven surfaces
when PreFlex is present. PreFlex also allows users to ascend ramps in a more anatomically correct way
by reducing the need for users to vault over a fully extended knee.
(2) Adaptive Yielding Control
The knee has an intelligent, auto adaptive control of stance exion (max 17°) and extension movements,
depending on the forces affecting the knee system. The varying stance exion resistance experienced
by the user is e.g. dependent on the behavior of the user, the surface condition and the angle of a slope
or incline.
(3) Dynamic Stability Control (DSC)
DSC ensures the knee will not release stance resistance during biomechanically unstable static and
dynamic conditions. Constantly checking multiple parameters, DSC ensures the optimally timed decision
for the knee to safely switch from stance to swing. Because DSC is always monitoring knee function,
multidirectional movement and walking backward are also possible without risk of stance resistance
releasing.
(4) Stance Release on Ramps
Although exed and partially loaded - the knee will release stance on hills and ramps to allow for greater
knee exion, improved swing phase clearance, and less hip exion force needed to bring the shank
into extension.
(5) Adaptive Swing Phase Control
Instantaneous adaptation to varied walking cadences and to changes of the pendular mass (i.g. varying
footgear) ensures the knee always achieves the swing exion target angle within (+/-) one degree. The
swing extension and exion resistance experienced by the user is autoadaptive.
Enabling the OPG function:
Enable the OPG function by selecting the corresponding checkbox. When this function is activated,
both stance phase extension and swing phase extension are adjusted automatically. This means that the
congurations in these areas are not necessary and the corresponding slider bars in the Swing phase
and Stance phase tabs of the adjustment software are deactivated.
INFORMATION
Your prosthetist can activate these MyModes using the X-Soft conguration software.

Ottobock | 35Genium - Bionic Prosthetic System
MyMode Switching without the Remote Control
If switching by bouncing was activated in the X-Soft conguration software, switching into the rst
MyMode without the Remote Control is accomplished by bouncing on the forefoot at least three times
within one second while maintaining ground contact and keeping the prosthetic leg extended. In doing
so, the forefoot has to bear approx. 40 % of the total body weight at peak load and less than approx.
25 % of the body weight at the lowest load. However, the load may not be taken off the foot fully.
1 2 3
1 sec.
3x in
1 sec.
After the audible signal is emitted (one long beep), your weight needs to be taken off the prosthesis
entirely for at least one second with the knee extended (no ground contact). The 3B1/ 3B1=ST knee
joint then switches to the rst MyMode and emits two short beeps.
The procedure for switching to the second MyMode is similar, but by bouncing four times. In this case,
the switch is indicated by three short beeps.
Returning to basic mode from any MyMode is accomplished by bouncing at least three times. The switch
is conrmed by a short beep.
If bouncing three times is activated but bouncing four times is not, any number of bounces greater than
or equal to 3 switches to the rst MyMode.
CAUTION
Improper MyMode switching. Incorrectly switching from MyModes into basic mode results in a risk
of falling (see the section MyMode Switching with the Remote Control)!
• After switching to one of the MyModes, check the functions since you may have accidentally
activated a different MyMode than you intended (see the sections MyMode Switching without the
Remote Control and MyMode Switching with the Remote Control).
• Ensure that you switch back to basic mode once your activities in the MyMode have ended.
INFORMATION
Switching back to basic mode by bouncing three or more times cannot be deactivated. This means
basic mode will be selected even if switching by bouncing was not activated in the X-Soft congura-
tion software.
Remote Control
During normal operation, the 3B1/ 3B1=ST knee joint can be used in basic mode (including optional
Intuitive Stance function, Sitting function, Stairs and Obstacles function, and OPG function) and in up
to ve different MyModes. The MyModes can be activated using the Remote Control.
Basic mode is used on a day-to-day basis, while the MyModes are pre-programmed for specic move-
ments and / or postures such as standing at a workbench, cycling, inline skating or cross-country skiing.

36 | Ottobock Genium - Bionic Prosthetic System
X-Soft is used to congure which MyModes are used as well as their settings. However, some parameters
can also be adjusted with the remote control.
CAUTION
Improper MyMode switching using the Remote Control. MyMode switching using the Remote Control
changes the cushioning properties of the knee joint. In certain situations, this can cause you to fall.
You must stand securely when switching between modes and must carefully conrm whether the
desired function was successfully set by the 3B1/3B1=ST knee joint.
CAUTION
Penetration of water into the Remote Control. The Remote Control is not waterproof. If water pen-
etrates the Remote Control, the device may be damaged (warranty will become void). This can lead to
malfunction of the Remote Control, result in unexpected actions of the knee joint and cause you to fall.
If penetrated by water, the Remote Control should be dried at room temperature for at least 1 day.
Before using the Remote Control again, send it to an authorised Ottobock Service Centre. Please
contact your prosthetist with any service questions.
CAUTION
Manipulation of the Remote Control. Any changes or modications you make to the Remote Control
on your own initiative can lead to malfunction and result in unexpected actions of the knee joint. This
can cause you to fall.
Any changes or modications to the device may limit its usability.
CAUTION
Unauthorised connection. If an unauthorised connection between a Remote Control and a knee joint
is established, the knee can react unexpectedly. This can lead to the patient falling. Pairing between
the knee and the Remote Control does not require any password or acknowledgment from the knee.
It is therefore theoretically possible (with known serial number of the knee or if only one knee is within
range of the Remote Control), that a third party performs pairing with the knee joint and changes
settings or switches MyModes.
INFORMATION
The knee joint should be consciously kept motionless during the switching process.
INFORMATION
For safety reasons, the Remote Control automatically turns off after two minutes. After the Remote
Control is turned on, approx. three seconds may elapse before if is ready for mode switching processes.
INFORMATION
The range of the Remote Control is max. 5 m.

The prosthetist‘s setting is usually found in the middle of the scale. After adjustment, you can reset
the prosthetist‘s setting by moving the slider control into the middle.
INFORMATION
The knee joint settings should be optimised by the prosthetist with the help of the X-Soft conguration
software. The Remote Control is not intended for use by the prosthetist in order to set up the knee
joint. The behaviour of the prosthesis can be changed to a certain extent on a day-to-day basis using
the Remote Control (e.g. while becoming accustomed to the prosthesis). At the next appointment,
the prosthetist can track the changes in the X-Soft conguration software.
The table below shows the adjustment parameters for the individual MyModes along with a brief de-
scription, the adjustment range of the Remote Control around the value selected by the prosthetist and
the absolute value range.

Deep sleep mode
The remote control can be used to place the knee joint in a deep sleep mode, in which power consump-
tion is minimised. The knee joint offers no functionality in this mode.
It can be awakened from deep sleep mode with the remote control or by connecting the charger.
Proceed as follows to activate deep sleep mode:
1. Select „Device stgs.“ in the main menu and conrm the selection.
2. A list of the parameters available for the current MyMode is displayed. The
entry „Deep sleep“ is at the end of this list; select it and press the enter key.
3. A conrmation prompt is displayed. Press the enter key again.
Proceed as follows to wake the knee using the Remote Control:
1. Activate the Remote Control by pressing the enter butt on and.
2. Select the “Wake device” menu entry and press the enter button to conrm.
3.
The knee joint is reactivated after no more than 20 seconds, which is conrmed by a single beep
and vibration signal. It will then be in basic mode.
Alternatively, the knee joint can be woken by connecting the charger.

Charging the Remote Control
Disconnect the charging cable from the charger of the 3B1/ 3B1=ST knee joint and connect it to the
charging receptacle on the Remote Control. Regardless of how often the Remote Control is used, it
should last two months on a single charge. The battery capacity of the Remote Control is shown at the
top left of the display (see Figure 1 in the section Initial Connection between the Remote Control and
3B1/ 3B1=ST Knee Joint (Pairing)). Fully charging the remote control battery takes a maximum of 3-4 hours.

As soon as the 3B1/ 3B1=ST knee joint identies an error in the knee joint, at least 5 beeps and 5
slow pulsating vibration signals are emitted. The 3B1/ 3B1=ST knee joint activates a safety mode and
remains in this state until the error is corrected (as long as the battery capacity is sufcient).
In addition to basic mode and the MyModes, the 3B1/ 3B1=ST knee joint has various safety modes that
offer different levels of residual functionality depending on the type and severity of the error.
The OPG function, stairs and obstacles function, Intuitive Stance function and Sitting function are deactivated
when the joint is in safety mode. Beyond that, the following levels of residual functionality are possible:
• Continuous high exion resistance
• Continuous stance phase exion resistance with the ability to initiate the swing phase
Depending on the type of error, protection against swing phase initiation while walking backwards
may or may not be active. You must therefore exercise caution when walking backwards after an error.
In addition, swing phase control and stance phase extension resistance may or may not be available
depending on the type of error.
If safety mode was triggered due to a at battery (see Section “Charging Status“), charging the pros-
thesis resets it to basic mode. In this case, the resistance value congured in the X-Soft adjustment
software is activated.
There is also an overheating mode to protect the knee joint against excessive temperatures. In this safety
mode, stance phase resistance increases as the temperature rises – especially in order to slow down walking
downhill so that overheating is not allowed to worsen. Swing phase control is also progressively reduced.
Overheating mode is indicated by brief vibration every 5s.
Basic mode is reactivated once the temperature has fallen sufciently.

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 exing 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 exion 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 ve 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 verication 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.
