Ottobock C-Leg 3C98-2 Information Für Träger Seite 36

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 you to fall.
If the safety mode is not deactivated by connecting and removing the battery charger, then a fault condition
exists. Contact a prosthetist to correct the problem.
Safety signal for incorrect connection to the tube adapter
If the tube adapter is somehow disconnected from the C-Leg joint while in operation (i. e. 1st, 2nd / 3rd or
standing mode with sufficient battery capacity), the C-Leg will emit short beeps and, for approximately five
minutes, vibrate with slow, pulsing signals. The C-Leg will activate the stance phase damping and maintain
it until the tube adapter cable is correctly attached (provided the battery capacity remains sufficient). Safety
signal occurs. The safety signal indicates an error of the joint. When in this condition, malfunctions can occur.
This can cause you to fall.
CAUTION
Safety signal occurs. The safety signal indicates an error of the joint. When in this condition, malfunctions
can occur. This can cause you to fall. In the event such a safety signal occurs, stop all activities with the
C-Leg and have the error resolved by your prosthetist.
Battery capacity
During normal operation in the 1st, 2nd and 3rd modes, the battery capacity is indicated with different vibra-
tion signals:
Battery capacity
Approx. 1 hour of operation remains
Approx. 30 minutes of operation remains
Immediately prior to switching into the safety mode
Empty battery mode
The C-Leg automatically switches to empty battery mode when the battery is almost empty. In this mode, the
prosthesis either sets "high flexion damping" (high safety/reduced comfort) or "low damping" (less safety/
higher activity). This allows you to walk even though the system is not active.
The standard factory setting for the knee joint is "high flexion damping". The prosthetist is responsible for
deciding whether you can safely use the "low damping" setting when the empty battery mode is active.
CAUTION
Danger when empty battery mode is activated. Depending on the setting (made by the prosthetist
using C-Soft V2.4 or higher), the prosthesis sets either "high flexion damping" (high safety/reduced comfort)
or "low damping" (less safety/higher activity) when empty battery mode is activated. In certain situations,
this can cause to fall.
For the „low damping" setting in empty battery mode, you must have the necessary muscular and cognitive
abilities to control a freely moving knee joint without stance phase stabilisation.
You can switch from empty battery mode to operating mode (1st mode) again by charging the knee joint.
