1) Thread the switch cable through the cable lock.
2) Secure the end of the switch cable with a button.
3) Tighten the switch cable and make a loop.
1) The level of compensation (flexion assistance) can
be adjusted and adapted to the weight of different
clothing with the AFB dial. Adjustments are easier
to make when the forearm is not flexed.
2) The adjustment mechanism is protected by a slip
coupling.
3) Hydrodynamic damping of the AFB mechanism is
designed to counterbalance the weight of the fore­
arm and terminal device. Therefore hold the upper
arm section of the prosthesis while testing the joint
function.
4) Position 1
Low compensation that allows natural free swing of
the arm while walking.
Position 2
Compensation increases progressively with flexion
of the arm and decreases automatically during
extension.
Position 3
Compensation remains constant. If set correctly,
the weight of the forearm is balanced by the com­
pensation and the forearm "floats".
Position 4
Low compensation until flexion stop.
► The upper arm rotation joint has bilateral stops (±
80 degrees) to block extreme movements. The fric­
tion of the humeral rotation feature at the upper arm
connection is easily adjusted by turning the external
adjustment screw.
