Patient Instructions
CAUTION
Magnetic interferences. The joint can malfunction when near high-tension power lines, transmitters, transform-
ers, CT scanners, or other sources of strong electromagnetic radiation (such as security systems for goods in
department stores). This can cause the patient to fall.
Avoid proximity to strong magnetic and electric interference sources (e.g. transformer stations, high-powered
radio or television transmitters).
CAUTION
Thermal overloading. Extended exposure to high temperatures can lead to defects and result in malfunction of
the joint up to loss of function due to structural failure. This can cause the patient to fall.
Avoid areas with extreme temperatures (see Section 3.3 "Technical Information").
CAUTION
Mechanical overloading. Exterior mechanical impact or stress such as shocks and vibrations can lead to
• short circuits in the electronics and battery and result in malfunction of the joint;
• defects on the battery and hydraulic damper resulting in leakage of liquid; or
• loss of function due to structural failure.
This can cause the patient to fall as well as result in skin irritation.
Do not expose system components to mechanical vibrations or shocks.
CAUTION
Penetration of dirt and humidity. Penetration of dirt and humidity into the system components can lead to
• short circuits in the electronics and battery and result in malfunction of the joint;
• defects on the hydraulic damper resulting in leakage of liquid; or
• loss of function due to structural failure.
This can cause the patient to fall as well as result in skin irritation.
• Do not let foreign particles or liquids enter the system components. Should the joint come into contact with
liquid, remove the cosmetic cover and let the components dry. The joint must then be sent to an authorized
Otto Bock Service for inspection. Your prosthetist is the contact person.
• Always use the protective plugs.
• If the C-Leg® comes into contact with salt water, immediately clean it with a cloth moistened with freshwater
and let it dry. The joint must then be sent to an authorized Otto Bock Service for inspection. Your prosthetist is
the contact person.
