2.9 C-Leg® Modes
2.9.1 1st Mode and 2nd Mode
INFORMATION
Advise your patients of the information in this section.
Upon delivery to the user, the C-Leg® must always be in the 1st mode.
For normal operation, the C-Leg® can be used in the 1st mode and in the 2nd mode. The 1st mode (optional with
standing mode) is for daily use while the 2nd mode allows for individual pre-programming for a specific type of
movement or position (e.g. cycling, inline skating, or cross-country skiing). The 2nd mode can be set and adapted
with the 4X180=* C-Soft adjustment software.
The user can change between the 1st and 2nd mode using either the remote control or with certain movements in
the joint.
For changing between the 1st and 2nd mode using the remote control, the following prerequisites have been deter-
mined:
CAUTION
Improper switching between modes with the remote control. When switching between modes with the
remote control, the damping behaviour of the joint changes. In certain situations, this can cause the patient to fall.
The patient must stand securely when switching between modes and must carefully confirm whether the desired
function was successfully set by the C-Leg®.
CAUTION
Penetration of water in the remote control. The remote control is not waterproof. If water penetrates the
remote control, the device may become damaged (guaranty will become void). This can lead to malfunction of the
remote control, result in unexpected actions of the joint, and cause the patient to fall.
Should water have penetrated the remote control, the device should be dried at room temperature for at least one
day. Before starting to reuse the remote control, return it to an authorized Otto Bock Service for inspection.
CAUTION
Manipulation on the remote control. Any changes or modifications you make to the remote control on your
own initiative can lead to malfunction and result in unexpected actions of the joint. This can cause the patient to
fall.
Any changes or modifications to the device may limit its use.
INFORMATION
Patient instructions for switching and configuring with the remote control!
Keep the joint and the residual limb still (no bending or extending!).
The remote control must be activated prior to switching between modes or configurations.
The remote automatically deactivates itself, if no action is performed within three seconds after activation of the
remote control (e.g. switching between 1st mode and 2nd mode, configuration of the standing mode functionality,
etc.).
For safety purposes, the working range of the remote control is limited to approximately 1 m. However, the remote
control will only function properly if held at least 30 cm away from the joint. If the mode switch was not performed,
ensure that the remote control is placed between 30 and 100 cm of the C-Leg® and repeat the command.
