Walking Down A Ramp; Walking Down Flat Steps; Kneeling; Changing Prosthesis Settings - Otto Bock C-Leg 3C98-3 Instructions For Use Manual

9.1.8 Walking down a ramp

Under increased flexion resistance, permit controlled flexion of the knee joint which lowers
the body's centre of gravity.
The swing phase is not triggered even though the knee joint is flexed.

9.1.9 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 contralateral side upon the subsequent
ground contact. This knee flexion should be initiated 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 supporting leg and the swing phase has to be ini­
tiated with the leg extended. If the foot is positioned so that it projects far beyond the edge of
the step in this situation, swing phase initiation may be surprising. However, the contralater­
al leg is ready to hold the weight in this situation.

9.1.10 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.

9.2 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/discon­
necting the battery charger. Bluetooth is then turned on for approx. 2 minutes. The connection must be estab­
lished 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
appears in the bottom row of the screen in the cockpit app.
• The O&P professional's setting is located in the middle of the scale. After making adjustments, this setting can
be restored by tapping the "Standard" button in the Cockpit 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 patient can use the app to change the behaviour of
the prosthesis to a certain extent during everyday use (e.g. while becoming accustomed to the prosthesis). The
O&P professional can use the adjustment software to trace these changes at the patient's next appointment.
• If the settings of a MyMode are to be modified, one must first switch to this MyMode.
