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. When the patient actively
flexes the hip joint at this point in time, this can cause the patient to fall. When walking backwards, secure the joint
actively with the residual limb muscles.
CAUTION
Risk of falling when going downstairs. When walking downstairs, the banister or handrail should always be
used and the prosthetic foot should be placed on the step so that the heel (max. centre of the foot) is close to the
edge of the step to facilitate rollover.
• Stop walking downstairs immediately whenever the sound warning beeps. Make careful tests to verify if the
stance phase stabilization is active (see Section 2.11 "Important User Instructions").
• Pay attention to the vibration and sound warnings (beeps) of the C-Leg compact.
• Special caution is required when walking downstairs while carrying children.
CAUTION
Non-active safety mode. If the safety mode can no longer be activated, there is the risk that the patient will fall.
If the C-Leg compact does not switch to the safety mode (e.g. due to short-circuit due to water penetration), the
amputee must actively stabilize the C-Leg compact at heel strike with his/her residual limb muscles until a prosthetist
can be reached or a prosthesis replacement be accomplished.
CAUTION
Self-discharge of the battery. When the joint is not in use for an extended period of time, self-discharge of the
battery will result. This can lead to insufficient power supply to the electronics of the joint and result in undefined con-
ditions. This can cause the patient to fall.
• We therefore recommend recharging prior to every use.
CAUTION
Results of product deterioration. Wear and tear on system components can lead to malfunction of the joint. This
can cause the patient to fall.
For your own safety, comply with the specified service and inspection intervals (maintenance of operational safety
and guaranty).
CAUTION
Malfunction of the joint. Malfunctions of the joint can cause the prosthesis wearer to fall.
Pay attention to the vibration and sound warnings (beeps) of the C-Leg compact.
INFORMATION
When using exoprosthetic knee joints, servomotoric, hydraulic, pneumatic or brake load dependent control functions
can cause movement noise. This kind of noise is normal and unavoidable. Usually, it does not cause any problems.
If the movement noise noticeably increases in the knee joint's life cycle, the joint should be inspected immediately by a
prosthetist.
CAUTION
Risk of pinching where the joint bends. Ensure that fingers and other body parts are not in this area when
bending the joint.
