C-Leg compact Prosthetic System
36 | Ottobock
The static alignment can be substantially improved using L.A.S.A.R. Posture 743L100. In order to ensure appropriate
stability combined with easy swing phase initiation, please proceed as follows:
1
After the self-calibration of the L.A.S.A.R. device, the load line can be measured. For that, the transfemoral am-
putee steps onto the force sensing plate with the C-Leg compact and onto the height compensation plate with the
other leg. The prosthetic side should be sufficiently loaded (> 35% of the body weight).
2
The 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 compact.
3
After adjusting the C-Leg compact with C-Soft (see Section 2.7 “C-Soft”) perform dynamic optimizations during
trial walking.
3.6 BionicLink / optional: Serial Data Cable
INFORMATION
Prior to connecting the 60X3 BionicLink, read the corresponding 647G192 Instructions for Use.

1
Remove the plastic cover of the protective elastomer cap.
2
Connect the wireless adapter cable (BionicLink) (optional: connect serial data cable: To do so, the protective elas-
tomer cap must be removed beforehand, Fig. 4.).
3
Snap the BionicLink into place and attach it medially (for left-side fittings) or laterally (for right-side fittings) to the
C-Leg compact.
3.7 C-Soft
INFORMATION
Prior to the parameter adjustment with 4X180=* C-Soft (compatible from version 2.0), read the corresponding
647G268 Instructions for Use.
INFORMATION
Ottobock Data Station is the platform for Ottobock applications such as C-Soft and others.
Ottobock C-Soft cannot be used without the Ottobock Data Station. The Ottobock Data Station is a standard com-
ponent of C-Soft and is automatically installed when installing C-Soft.
3.8 Optional: Parameter Settings with Foam Cover and C-Soft
The 3S26 and 3R59 Foam Covers can be used for the cosmetic enhancement of the leg prosthesis.
For that purpose, a 4X78 Charger Extension Cable can be integrated into the C-Leg compact fitting. If the charger
extension cable is not used, a connection cap made of 2 mm Pedilin® makes it possible to pull down the foam cover in
order to reach the charging receptacle at the C-Leg compact.
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 the same amount.
The mounted foam cover changes the damping behaviour. With the 60X3 BionicLink (wireless programming interface),
which is attached below the pre-shaped foam block, the damping behaviour can be completely taken into account by
changing the parameter settings.
That process furthermore requires the 60X5 (60X4) BionicLink PC for the data transfer and the 4X180=* C-Soft (from
version 2.0) for the parameter adjustment (see Section 2.7 “C-Soft”).
