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
conditions. This can cause the patient to fall.
• We therefore recommend recharging prior to every use.
• Prior to using the C-Leg in the 2nd/3rd mode (e.g. bike riding), check the battery status. To do so, attach the
charger to the C-Leg. The yellow LED should flash (battery is charged more than a half) or should not be lit
(battery is fully charged). Using the C-Leg in the 2nd/3rd mode with insufficient battery capacity may cause
the C-Leg to switch into the safety mode (see Section "2.12 Important User Instructions").
CAUTION
Improper switching between modes. An incorrect switch from the 2nd/3rd mode into the 1st mode creates
the risk of falling (see Section 2.9 "C-Leg Modes")!
CAUTION
Switching between modes with the remote control. The patient can use the remote control to initiate dif-
ferent actions. As a result the damping behaviour of the joint will change. In certain situations, this can cause the
patient to fall.
In the case that you have mistakenly selected an unwanted action with the remote control (vibration or sound
signal), unweight the C-Leg and select a new command.
WARNING
Risk of accident when driving a motor vehicle. The ability of leg prosthesis users to drive a motor vehicle
is determined on a case-by-case basis. Criteria include the type of fitting (amputation level, unilateral or bilateral,
residual limb conditions, design of the prosthesis) and the amputee's individual abilities. All persons are required
to observe their country's national and state driving laws when operating motor vehicles. For insurance purposes,
drivers should have their driving ability examined and approved by an authorized test centre. Ottobock recom-
mends that the motor vehicle be professionally retrofitted to the user's individual needs (e.g. automatic shift). Risk-
free driving must be ensured even when the leg prosthesis is not functioning.
Before operating a motor vehicle, make sure to turn off the standing mode feature using the remote control unit.
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.
INFORMATION
When using exoprosthetic knee joints, servomotoric, hydraulic, pneumatic or brake load dependent control func-
tions 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.
