General Safety Instructions
CAUTION
Alignment and adjustment error. During alignment and adjustment of the prosthesis, errors can occur result-
ing in malfunction of the joint up to loss of function due to structural failure. This can cause the patient to fall.
• Participation in an Ottobock product training course for the C-Leg is obligatory before the first fitting.
Additional product training courses may become necessary to qualify for fitting product updates.
• The tubes must not be shortened as that may damage the integrated strain gauges.
• During the data transfer (PC to C-Leg), the prosthesis wearer must remain standing or sitting still and the
BionicLink or the communication cable must not be removed.
• If the prosthesis wearer uses crutches or walking canes during adjustment, readjustment is required as soon
as he stops using these walking aids.
CAUTION
Use of inappropriate prosthetic components. If inappropriate prosthetic components are installed in the
prosthesis, malfunction of the joints can occur up to loss of function due to structural failure. This can cause the
patient to fall.
Combine the C-Leg only with adapters and feet approved by Ottobock (see component overview on the folded
front page).
CAUTION
Manipulations on system components. Any changes or modifications you make to system components on
your own initiative can lead to malfunction of the joint up to loss of function due to structural failure. This can
cause the patient to fall.
• Any changes or modifications to the device may limit its use.
• The opening and repairing of the joint may only be performed by authorized Ottobock technicians, and the
handling of the battery may only be carried out by Ottobock Service Centres (exchanges are not permissible).
CAUTION
Incorrect battery charging. Charging the battery with battery chargers that have not been approved by Ottob-
ock can lead to defects and result in malfunction of the joint. This can cause the patient to fall.
Advise the patient about the charging procedure and refer to the Patient Information. Advise the patient of the fol-
lowing patient instructions.
CAUTION
Improper use of the joint. Any kind of overloading or excessive strain as well as improper use can lead to de-
fects and result in malfunction of the joint up to loss of function due to structural failure. This can cause the patient
to fall.
Advise the patient of the proper use of the C-Leg as well as of the following patient instructions.
CAUTION
Improper use of the remote control. The remote control can get damaged by improper use. This can lead to
malfunction of the remote control and result in unexpected actions of the joint. This can cause the patient to fall.
Advise the patient about the proper use of the remote control and refer to the Patient Information. Advise the
patient of the following patient instructions.
CAUTION
Switching between modes with the remote control. When switching between modes with the remote con-
trol, the damping behaviour of the joint changes. In certain situations, this can cause the patient to fall.
Advise the patients about the switching into the 2nd mode and refer to the Patient Information. Advise the patient
of the following patient instructions.
