Please pay special attentionto the safety instructions!The patient must be taught how to handle, care for and operate his/her prosthesis properly. Please seethe following sections: 1.3 Operational conditions, 1.5 Safety instructions, 2.4 Charging the C-Leg®knee joint system, 2.9 Remote control and switching into 2nd mode, 2.11 Important user instructions,3.1 Service intervals, 3.3 Technical information, 3.6 Liability1.1 Medical purposeThe C-Leg® knee joints 3C98-1 and 3C88-1 are to be used exclusively for the exoprosthetic fitting of the lowerextremity.1.2 Field of applicationThe C-Leg® was designed for a broad field of application and can be used by transfemoral amputees as well as byactive hip disarticulation amputees. For knee disarticulation amputees, a version for long residual limbs is available(3C88-1).Field of application according to the Mobility System:Recommended for  (unrestricted outdoor walkers and unrestricted outdoorwalkers with especially rigorous demands).Approved for a .Exception:The 2R80=110 Tube Adapter
51.3 Operational conditionsInformation:Advise your patients of the information in this section.The C-Leg® was developed for everyday activities and not for extreme sports such as free climbing, parachuting orparagliding. For the necessary environmental conditions, please see Section 3.3 Technical information.The C-Leg® prosthesis system is designed exclusively for use on one patient. Use of the product by a further personis not approved by the manufacturer.The fitting of a patient with a C-Leg® may only be carried out by prosthetists who have been authorized with thecorresponding Otto Bock training.1.5 Safety instructionsInformation:Advise your patients of the information in this section.Attention:Failure to follow the below-mentioned safety instructions can lead to a faulty control or malfunction of theC-Leg® and result in risk of injuries for the patient as well as damages to the C-Leg®.General Safety InstructionsParticipation in an Otto Bock product training course for the C-Leg® is obligatory before the first fitting. Additionalproduct training courses may become necessary to qualify for fitting product updates.In the interest of the patient (operational safety and warranty), the C-Leg® should be sent in for maintenance atthe specified service intervals.Do not shorten the tubes as that may damage the integrated strain gauges.During the data transfer (PC to C-Leg®), the patient must remain still and the BionicLink or the communicationcable must not be removed.Patients who have been using forearm crutches or a cane during the dynamic adjustment of the maximum loadgenerally become more active within a very short time. For that reason it is indispensable to check and possiblyreadjust the settings. A readjustment of the C-Leg® settings is also required for patients who switch from forearmcrutches to a cane or to no walking aid at all.Any changes or modifications of the device can lead to restrictions of usage. Patients are to be advised aboutthe charging procedure, the proper handling of the remote control as well as the switching into the 2nd mode. Thefollowing patient information (pages 6 f.) should be handed to the patient.The opening and repairing of the joint may only be performed by authorized Otto Bock technicians and thehandling of the battery may only be carried out by Otto Bock service centers (exchanges are not permissible).The C-Leg® may only be used with the specified prosthetic feet and must not be used with components from othermanufacturers (warranty will become void). (Please see component overview on the folded front page).Always use the shipping case for transport.
6Patient InformationIn the case that you commanded an unwanted action with the remote control by mistake (vibration or sound sig-nal), relieve the C-Leg® of any load and rectify the command.Avoid proximity to strong magnetic and electric interference sources (e.g. transformer stations, high-poweredradio or television transmitters) as well as areas with extreme temperatures or humidity.Do not subject the system components to intensive smoke, dust, or mechanical vibrations or jolts.Neither solid particles nor liquids should penetrate the system components. Should the joint come into contactwith liquid, remove the cosmetic cover and let the components dry. The joint should then be sent to an authorizedOtto Bock service for inspection. Your prosthetist is the contact person.Should the C-Leg® come into contact with salt water, clean it immediately with a cloth moistened with freshwaterand let it dry. The joint should then be sent to an authorized Otto Bock service for inspection. Your prosthetist isthe contact person.The C-Leg® has been developed for everyday use and must not be used for unusual activities such as extremesports (i.e. free climbing, paragliding, etc.). Careful handling of the prosthesis and its components not onlyincreases their service life but, above all, ensures the patients safety. Should the prosthesis be subjected to un-usual stress (e.g. a fall), contact your prosthetist immediately and have the prosthesis inspected for any damage.If necessary, the responsible prosthetist will pass the prosthesis on to the Otto Bock Service.The hydraulic unit may overheat during extended, continuous use (e.g. lengthy downhill walks). In that case, the alarmwill repeatedly vibrate to alert you of the risk of overheating. As soon as these vibrations begin, stop all activities andallow the hydraulic unit to cool down. Avoid touching the hot parts! You may resume your activities once the vibrationsignals stop. If activities are continued despite the vibration signals, the hydraulic element may overheat and, inextreme cases, lead to a damage to the C-Leg®. The joint should be serviced following a case of overheating.When walking backwards, always put your heel down first. Putting down the toe first when walking backwardsresults in the risk of falling, because the C-Leg® can then switch from the high stance phase value to flexion.When walking up or down stairs, always use the banister or handrail. When walking down stairs the prostheticfoot should be placed on the step so that the heel and posterior half of the foot contact the tread surface; the fore-foot may extend beyond the riser to make knee flexion easier.Stop walking up or down the stairs immediately whenever the sound warning beeps. Make careful tests to verify ifthe stance phase stabilization is active (see Section 2.11 Important user instructions).When the C-Leg® is not in use for an extended period of time, the battery may become discharged. We thereforerecommend recharging prior to use.Prior to using the C-Leg® in the 2nd mode (e.g. bike riding), check the battery status. To do so, attach the chargerto the C-Leg®. The yellow LED should flash (battery is charged more than a half) or should not be lit (battery isfully charged). Using the C-Leg® in the 2nd mode with insufficient power supply may cause the joint to switch intothe safety mode (see Section 2.11 Important user instructions).An incorrect switch from the 2nd mode into the 1st mode creates the risk of falling (see Section 2.9 Remote controland switching into the 2nd mode)!For your own safety, comply with the specified service and inspection intervals.The ability of leg prosthesis users to drive a vehicle is determined on a case-by-case basis. Criteria include the typeof fitting (amputation level, unilateral or bilateral, residual limb conditions, design of the prosthesis) and the ampu-tees individual abilities. All persons are required to observe their countrys national and state driving laws whenoperating vehicles. For insurance purposes, drivers should have their driving ability examined and approved by anauthorized test center. Otto Bock recommends that the vehicle be professionally retrofitted to the users individualneeds (e.g. automatic shift). Risk-free driving must be ensured even when the prosthesis is not functioning.Always use the protective plugs.Pay attention to the vibration and sound warnings (beeps) of the C-Leg®.
72.1 Connecting the tube adapter1 2 3 41Mount the foot to the tube adapter (lightly tighten the screws).2Plug the tube adapter plug onto the knee joint (only one polarity possible).3Push the protruding cable into the tube and push the tube adapter into the C-Leg®. In doing so, take care toachieve the minimum insertion depth (see following table).max. 75 kg / 165 lbs 75 kg - 100 kg /165 lbs - 220 lbs 100 kg - 125 kg /220 lbs - 275 lbs50 mmmax. adjust-ment range45 mmmax. adjust-ment range40 mmmax. adjust-ment rangeCaution:With the 3C98-1 and 3C88-1 models, the scaling must be positioned in front of the tube (With the formermodels 3C98 and 3C88, the scaling had to be on the back of the tube).4Turn the foot slightly outward (adjustment range +/-30° to suit the needs of the patient) and pre-fasten thescrews lightly at the clamp.

We recommend charging the batteryover night when using the prosthesis on a daily basis.Charging is only possible at temperatures above 0 °C.
122.5 Static alignment optimization (with LASAR Posture)Load line 30 mm infront of alignmentreference pointLoad lineAlignment referencepointThe static alignment can be considerably optimized with the help of the LASAR Posture. In order to ensure anappropriate stability and at the same time an easy swing phase initiation, proceed as follows:1After the self-calibration of the LASAR device, the load line can be measured. For that, the transfemoral ampu-tee steps onto the force sensing plate with the C-Leg® and onto the height compensation plate with the otherleg. The prosthesis side must be sufficiently loaded (>35% of body weight).2The alignment is adapted exclusively by modifying the plantar flexion so that the load line/laser line runs approxi-mately 30 mm in front of the alignment reference point (=knee axis) of the C-Leg®.3After adjusting the C-Leg® with C-Soft® (see Section 2.7 C-Soft) perform dynamic optimizations during trialwalking.
132.6 BionicLink/optional: Serial data cableNote:Prior to connecting the 60X3 BionicLink, read the corresponding 647G192 Instructions for Use.1 2 3 41Connect the wireless adapter cable (BionicLink) (optional: connect serial data cable).2Engage the BionicLink into the C-Leg® and attach it medially (for left fittings) or laterally (for right fittings) at theC-Leg®.2.7 C-SoftNote:Prior to the parameter adjustment with 4X180=V1.0 C-Soft, read the corresponding 647G268 Instruc-tions for Use.Prior to the parameter adjustment with the old Sliders adjustment software, download and readthe corresponding instructions for use at www.ottobock.com/en/sliders. The remainder of this sec-tion can then be skipped.Information:Otto Bock Data Station is the platform for Otto Bock applications such as C-Soft and others.Otto Bock C-Soft cannot be used without the Otto Bock Data Station. The Otto Bock Data Station is astandard component of C-Soft and is automatically installed when installing C-Soft.

152.8 Optional: Parameter settings with foam cover and C-SoftThe foam covers 3S26 or 3R59 can be used for the cosmetic enhancement of the leg prosthesis.For that purpose, a 4X78 Charger Extension Cable can be integrated in the C-Leg® fitting. If the charger extensioncable is not used, a connection cap made of 2 mm Pedilin® allows to pull down the foam cover in order to reach thecharging receptacle at the C-Leg®.Allow a 60 mm compression allowance to minimize the effect of the protective foam cover on the knee function.When determining the proper cover length, increase the thigh dimension by 30 mm and the shin dimension by thesame amount.The mounted foam cover changes the damping behavior. With the 60X3 BionicLink (wireless programming inter-face), which is attached below the pre-shaped foam block, the damping behavior can be completely taken intoaccount by adapting the parameter settings.That process furthermore requires the 60X4 BionicLink PC for the data transfer and the 4X180 C-Soft for the pa-rameter adjustment (see Section 2.7 C-Soft ).2.9 Remote control and switching into 2nd modeInformation:Advise your patients of the information in this section.For normal operation, the C-Leg® can be used in the 1st mode (optional with standing mode) and in the 2nd mode.The 1st mode is for daily use while the 2nd mode allows to individually pre-program a specific type of movement orposition (e.g. cycling, inline skating, or jogging). The 2nd mode can be set and adapted with the 4X180=V1.0 C-Softadjustment software (or the Slider adjustment software).Attention:The patient must stand securely when performing any switch and must test with caution whether thedesired function was successfully set by the C-Leg®.The remote control is not waterproof. If water penetrates the remote control, the device may becomedamaged (warranty will become void). The device should then be dried at room temperature for atleast 1 day. If defective, the remote control should be sent to an authorized Otto Bock Service.Important user information for switches and configurations:Deliberately maintain the joint and the residual limb still (no bending or extending!).The remote control must be activated prior to any switches or configurations.The remote control turns off automatically after prolonged non-use. For safety purposes, the switch willonly be possible a few seconds following the activation.For safety purposes, the working range of the remote control is limited to approximately 100 cm.However, the remote control will only function properly if held at least 30 cm away from the joint. If theswitch was not performed, ensure that the remote control is placed within the right distance range ofthe C-Leg® and repeat the command.
17:Information:This functionality is not intended for joint adjustment by the prosthetist, who should adjust the joint bymeans of the C-Soft (Slider) adjustment software. Rather, this functionality is designed so that thepatient can adapt the damping behavior slightly during everyday use (e.g. when getting used to theprosthesis or for a changed gait pattern). For safety purposes, the damping behavior can only beslightly changed with the remote control. Changes to the damping behavior which were effected withthe remote control are not displayed by the C-Soft (Slider).Attention:The patient must stand very securely during this procedure.After activation of the remote control, the selectionsteps Comfort - Standard - Dynamic must be setby pressing key 3 in combination with keys 1 or 2.The successful setting of the damping parametersis confirmed acoustically with the following beepsignals:Comfort = 1x beep signalStandard = 2x beep signalsDynamic = 3x beep signals (Connecting the C-Leg® to the remote control):Pairing does not have to be performed upon delivery. Pairing must be done as soon as a new remote control (replacement) is used with the C-Leg®.if a configuration or mode switch cannot be effected with a fully charged battery of both the joint and the re-mote control within the working range of the remote control (1 m).Execution:Attention:Given that only one joint can be paired with a remote control, it must be ensured that no other joint is inthe circumference of 3 m during the pairing.Briefly press the start button by reaching with a thin object (e.g. a paper clip) through the small hole of the re-mote control. The joint will confirm the successful pairing with 5 short beep signals.2.9.3 Changing the battery of the remote controlAttention:The battery of the remote control may only be changed by an authorized Otto Bock Service. The battery isautomatically replaced at the biennial service intervals (see 646A140 C-Leg® Warranty Concept).To change a battery outside of the biennial service intervals, send the remote control to an authorizedOtto Bock Service. Upon receipt of the remote control with a new battery, the remote control must bepaired with the C-Leg® (see Section 2.9.2).
182.9.4 Optional: Switching between 1st mode and 2nd mode without the remote control211 2 31 second3 × in 1second1Rock up and down on the forefoot while maintaining continuous ground contact and a speed of at least3 rocking movements per second (The foot must bear at least 70% of the maximum load. When relieving thefoot, the foot must bear at least 15% of the maximum load).2Once the acoustic signal beeps, lift the prosthesis for at least one second (no ground contact).3With further sound signals, the prosthesis acknowledges receipt of the switch command and switches to theother mode (1st mode = 1 beep signal or 2nd mode = 2 beep signals).2.10 Finalizing the prosthesisUpon finalizing all settings, all screws must be fastened and tightened to the proper torque.1Optional: Remove the cosmetic foam cover (and also the BionicLink, if need be).2Secure all screws required for the prosthesis alignment (see Section 2.3) with 636K13 Loctite.3Fasten all screws to the right torque (see Section 2.3) with the 710D4 Torque Wrench.4Optional: Apply the cosmetic foam cover or the 4X160 C-Leg® Protector.2.11 Important user instructionsInformation:Advise your patients of the information in this section.Safety modeAside from the operation modes (1st and 2nd mode), the C-Leg® has a safety mode. As soon as a critical erroroccurs in the system or when the battery is almost empty, the C-Leg® automatically switches to the safety mode. Inthat mode, the prosthesis activates a high flexion damping (high safety/reduced comfort), which enables the patientto walk safely despite a non-active system.The switch to the safety mode is announced immediately prior to the switch with sound and vibration signals. If thesafety mode was prompted by an empty battery, recharge the battery. The joint will then switch back automaticallyto the operation mode (1st mode).
19Caution:Non-active safety mode!If the C-Leg® does not switch to the safety mode (e.g. due to short-circuit due to water penetration), theamputee must actively stabilize the C-Leg® at heel strike with his/her residual limb muscles until a prosthetistcan be reached or a prosthesis replacement be accomplished.Safety mode is activated!As soon as the sound and vibration signals go off simultaneously, the patient must stop all activities with theleg prosthesis. After approximately 10 seconds, the patient must check if the safety mode is activated withthe high flexion damping in a safe standing position with repeated slight bending of the C-Leg® and undercontrolled weight bearing.Safety mode cannot be deactivated!If the safety mode could not be deactivated by recharging the battery, an error has occured. Contact yourprosthetist for troubleshooting.Battery capacityDuring normal operation in the 1st and 2nd modes, the battery capacity is indicated with different vibration signals:Battery capacity Vibration impulseApprox. 1 hour of operation remains 3×Approx. 30 min. of operation remains 5×when turning off 10 ×, then turns offAs soon as the tube adapter has no connection when the C-Leg® is in operation (i.e. 1st, 2nd or standing mode withsufficient battery capacity), the C-Leg® emits short beeps and, for the duration of approximately five minutes, slowlypulsing vibration signals. The C-Leg® activates the stance phase damping, which it maintains until the connection ofthe tube adapter is properly reset (provided the battery capacity remains sufficient).Caution:In the case of such a safety warning, stop any operation of the C-Leg® and resolve the error by properlyconnecting the tube adapter (by the prosthetist or service technician).Insofar as a contact failure has occured between the plug of the tube adapter and the C-Leg® (e.g. followingthe fitting by the prosthetist), send the knee joint (incl. tube adapter) to an authorized Otto Bock Service.VentilationAfter extended non-vertical storage of the C-Leg®, air may accumulate in the hydraulic unit. This is noticeablethrough sounds and irregular damping behavior.The automatic ventilation mechanism ensures that all functions of the C-Leg® are again intact after approximately10 - 20 steps.
