Important User Instructions
Safety mode
Aside from the normal operation mode, the C-Leg®compact has
a safety mode. As soon as a critical error occurs in the system or
when the battery is almost empty, the C-Leg®compact automatically
switches to the safety mode. In that mode, the prosthesis activates
a high flexion damping (high safety/reduced comfort), which makes
it possible 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.
Non-active safety mode. If the safety mode can no longer
CAUTION
be activated, there is the risk that you will fall. If the C-Leg®compact
does not switch to the safety mode (e.g. due to short-circuit due to
water penetration), you must actively stabilize the C-Leg®compact
at heel strike with your residual limb muscles until a prosthetist can
be reached or a prosthesis replacement be accomplished.
Danger when activating the safety mode. Upon
CAUTION
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®compact repeatedly under controlled
weight bearing.
Safety mode cannot be deactivated. If the joint is
CAUTION
exclusively in the safety mode, the joint has a defect. When in this
condition, malfunctions can occur. This can cause you to fall. If the
safety mode could not be deactivated by recharging the battery, an
error has occurred. Contact your prosthetist for troubleshooting.
