Opg Function (Optimised Physiological Gait); Additional Operating States (Modes); Empty Battery Mode; Mode For Charging The Prosthesis - Otto Bock Genium 3B1 Instructions For Use Manual

Additional operating states (modes)

→ The activation of deep sleep mode is indicated by a short beep signal and a short vibration signal. Also the
remote control is turned off.
Deactivating deep sleep mode
1) Use the key to activate the remote control.
2) With the key, establish a connection to the prosthesis. Establishing the connection to the prosthesis deactiv­
ates deep sleep mode.
INFORMATION: Establishing a connection in deep sleep mode can take up to 30 seconds.

10.8 OPG function (Optimised Physiological Gait)

INFORMATION
To use this function, it needs to be enabled in the adjustment software.
The OPG function minimises the prosthesis wearer's prosthetic deviations from a harmonious gait pattern and pro­
motes more biomechanically correct walking. Selection of this function enables the following features:
PreFlex
PreFlex ensures the knee is in 4° of flexion at the end of swing phase in preparation for loading response. This
makes initiating stance phase flexion easier and forward movement is less restricted.
Adaptive yielding control
The knee joint has auto-adaptive stance and swing extension resistance. The stance flexion resistance experienced
by the user is dependent on the slope or incline when walking downhill. When walking on a ramp, adaptive yielding
control manages flexion depending on the angle of the ramp. The knee joint flexes slowly if the ramp is flat, and
flexes quickly if the ramp is steep.
Dynamic stability control (DSC)
DSC ensures the knee will not release stance resistance during biomechanically unstable static and dynamic con­
ditions. 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, multi-directional movement and
walking backward are also possible without risk of stance resistance releasing.
Adaptive swing phase control
Instantaneous adaptation to varied walking cadences and to changes of the pendular mass (e.g. varying footgear)
ensures the knee always achieves the swing flexion target angle within (+/-) one degree. The swing phase exten­
sion and flexion resistance experienced by the user are auto-adaptive.
The flexed and partially loaded knee will also disable the stance phase on slopes and ramps to allow for greater
knee flexion and more ground clearance in the swing phase.
11 Additional operating states (modes)

11.1 Empty battery mode

Beeps and vibration signals are emitted if the available battery charge level is 5% (see Page 91). During this time,
damping settings are set to their safety mode values. The prosthesis is then switched off. You can switch back to
basic mode (mode 1) from empty battery mode by charging the product.

11.2 Mode for charging the prosthesis

The product is non-functional during charging.
The product is set to safety mode damping. This may be low or high depending on the setting in the adjustment
software.

11.3 Safety mode

The product automatically switches to safety mode if a critical system fault occurs (e.g. failure of a sensor signal).
Safety mode remains in effect until the error has been rectified.
The switch to safety mode is indicated by beeps and vibration signals immediately prior to switching (see Page 91).
Safety mode can be disabled by connecting and disconnecting the battery charger. If the product switches into
safety mode again, this means a permanent error exists. The product must be inspected by an authorised Ottobock
Service Centre.
Depending on the type and severity of the error, different remaining functionality is offered in safety mode which
enables limited walking by the user.
