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.
Safety Messages and Safety Mode
Event
Overheated hydraulics
Minor error:
e.g. temporary disrup-
tion of a sensor signal
Moderate error:
e.g. a sensor is not
operational
Severe error:
e.g. failure of the valve
drive
Total failure:
No electronic func-
tionality
As soon as the 3B1/ 3B1=ST knee joint identifies 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 sufficient).
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 flexion resistance
• Continuous stance phase flexion 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 flat battery (see Section "Charging Status"), charging the pros-
thesis resets it to basic mode. In this case, the resistance value configured 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 sufficiently.
