Ottobock C-Leg compact 3C96-1 Instrucciones De Uso página 18

CAUTION
Overheating of the hydraulic unit. Extended, continuous use (e.g. lengthy downhill walks) can lead to
• overheating of the hydraulic unit and result in malfunction of the joint; or
• defects on the hydraulic damper resulting in leakage of liquid.
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 a damage to the C-Leg compact. The joint should then be sent to an
authorized Ottobock 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 compact can switch from the high stance phase resistance to swing phase resistance.
Actively flexing the hip joint at this point in time can cause you to fall.
When walking backwards, secure the joint actively with the residual limb muscles.
CAUTION
Non-active safety mode. If the safety mode can no longer 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.
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 you 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 Ottobock Service for inspection. Your prosthetist is the contact person.
