Ottobock C-Leg Serie Información Para El Usuario página 23

This can cause you to fall as well as result in skin irritation. Touching overheated components can cause burns.
Pay attention to the vibration signals that will occur in such cases to alert you that there is a risk of overheating.
As soon as these vibrations begin, all activities must be stopped and the hydraulic unit be allowed to cool
down. You may resume your activities once the vibration signals stop.
If activities are continued despite the vibration signals, the hydraulic element may overheat and, in extreme
cases, lead to damage to the C-Leg. The joint should then be sent to an authorised Otto Bock Service for
inspection. Your prosthetist is the contact person.
CAUTION
Risk of falling when walking backwards. When putting down the toe first when walking backwards, the
C-Leg can switch from the high stance phase resistance to swing phase resistance. When the patient
actively flexes the hip joint at this point in time, this can cause you to fall. When walking backwards, secure
the joint actively with the residual limb muscles.
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 you 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 plug protectors / plug covers.
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.
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 you to fall.
Avoid areas with extreme temperatures (see Section "Technical Information").
