2.11 Finishing the Prosthesis

Upon finalizing all settings, all screws must be fastened and tightened to the proper torque.
1 Optional: Remove the cosmetic foam cover (and also the BionicLink, if present).
2 Secure all screws required for the prosthesis alignment (see Section 2.3) with 636K13 Loctite.
3 Tighten all screws to the proper torque (see Section 2.3) with the 710D4 Torque Wrench.
4 Optional: Apply the cosmetic foam cover or the 4X160=* C-Leg® Protector.

2.12 Important User Instructions

INFORMATION
Advise your patients of the information in this section.
Safety mode
CAUTION
Non-active safety mode. If the safety mode can no longer be activated, there is the risk that the patient will fall.
If the C-Leg® does not switch to the safety mode (e.g. because of a short-circuit due to water penetration), the
amputee must actively stabilize the C-Leg® at heel strike with his/her residual limb muscles until a prosthetist can
be reached or a prosthesis replacement be accomplished.
CAUTION
Danger when activating the safety mode. Upon activation of the safety mode, the damping behaviour of the
joint changes. In certain situations, this can cause the patient to fall.
As soon as the sound and vibration signals go off simultaneously, the prosthesis wearer must stop all activities
with the leg prosthesis. After approximately 10 seconds, and from a secure standing position, check to see if the
safety mode with the high flexion damping has been activated by slightly bending the C-Leg® repeatedly under
controlled weight bearing.
CAUTION
Safety mode cannot be deactivated. If the joint is exclusively in the safety mode, the joint has a defect. When
in this condition, malfunctions can occur. This can cause the patient to fall.
If the safety mode could not be deactivated by recharging the battery, an error has occurred. Contact your pros-
thetist for troubleshooting.
Aside from the operation modes (1st and 2nd mode), the CLeg® has a safety mode. As soon as a critical error
occurs in the system or when the battery is almost empty, the C-Leg® automatically switches to the safety mode. In
that mode, the prosthesis activates a high flexion damping (high safety/reduced comfort), which enables the patient
to walk safely despite a non-active system.
The switch to the safety mode is announced immediately prior to the switch with sound and vibration signals. If the
safety mode was prompted by an empty battery, recharge the battery. The joint will then switch back automatically
to the operation mode (1st mode).
