Walking Down Flat Steps; Kneeling; Changing Prosthesis Settings - Ottobock C-Leg 3C98-3 Gebrauchsanweisung

8.1.9 Walking down flat steps

To walk down ramps, flat steps or curbs, walking step-over-step with knee
flexion under load is recommended for the best possible relief of the contralat­
eral side upon the subsequent ground contact. This knee flexion should be ini­
tiated immediately upon heel strike, or as long as the prosthetic leg is still in
front of the body.
For skilled users the prosthesis offers the option of initiating a swing phase
while walking down ramps and crossing flat steps (such as curbs). In order to
do so, the body's centre of gravity has to be far enough in front of the support­
ing leg and the swing phase has to be initiated with the leg extended. If the
foot is positioned so that it projects far beyond the edge of the step in this situ­
ation, swing phase initiation may be surprising. However, the contralateral leg
is ready to hold the weight in this situation.

8.1.10 Kneeling

Under increased flexion resistance, permit controlled flexion of the knee joint
to gradually reach the kneeling position. A hard impact of the knee joint on the
ground should be avoided so the electronics are not damaged.
Using the 4X860=* C-Leg protector is recommended for kneeling frequently.

8.2 Changing prosthesis settings

Once an active connection to a component has been established, the settings of the respective
active mode can be changed using the Cockpit app.
INFORMATION
Bluetooth on the prosthesis must be switched on to change the prosthesis settings.
If Bluetooth is switched off, it can be turned on by turning the prosthesis upside-down or by
connecting/disconnecting the battery charger. Bluetooth is then turned on for approx. 2
minutes. The connection must be established during this period.
Information for changing the prosthesis settings
• Before changing settings, always check the main menu of the Cockpit app to make sure the
correct component has been selected. Otherwise parameters could be changed for the
wrong component.
• It is not possible to change prosthesis settings nor to switch to a different mode while the
prosthesis battery is being charged. Only the status of the prosthesis can be called up.
Instead of the
pit app.
• Prosthesis settings should be optimised using the adjustment software. The Cockpit app is
not intended for use by the O&P professional to set up the prosthesis. The everyday behaviour
of the prosthesis can be changed to a certain extent using the app (e.g. while becoming
accustomed to the prosthesis). The O&P professional can use the adjustment software to
trace these changes at the next appointment.
• If the settings of a MyMode are to be modified, one must first switch to this MyMode.
