Changing the Battery of the Remote Control

CAUTION
Impermissible battery replacement of the remote control. Replacing the battery on your own initiative
can result in defects of the remote control. Malfunction and subsequent unexpected actions of the joint are
then possible. This can cause you to fall.
The battery of the remot control may only be changed by an authorised Otto Bock Service Centre.
To change a battery outside of the service intervals, send the remote control to an authorised Otto Bock
Service. Upon receipt of the remote control with control with a new battery, the remote control must be
paired with the C-Leg. Your prosthetist is the contact person.
Important user instructions

Safety Mode

Besides the operation modes (1st, 2nd and 3rd mode) and the standing mode, the C-Leg also has a safety
mode. If a critical error occurs in the system, the C-Leg will immediately switch to the safety mode. In that
mode, the prosthesis will not easily flex (high safety/reduced comfort). This allows you to walk even though
the system is not active.
The switch to the safety mode will be announced immediately prior to the switch with sound and vibration signals.
CAUTION
Non‑active safety mode. If the safety mode can no longer be activated, there is the risk that you will fall.
If the C-Leg does not switch to the safety mode (e.g. due to short-circuit due to water penetration), you must
actively stabilise the C-Leg at heel strike with your residual limb muscles until a prosthetist can be reached
or a prosthesis replacement be accomplished. Immediately contact your prosthetist.
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 you to fall.
As soon as the sound and vibration signals go off simultaneously, you 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.
