CAUTION
Sudden flexion of the DynamicArm. When the arm
is extended the lock is released. Sudden flexion of
the DynamicArm can occur during taking on, taking
off or storage, resulting in injury.
Always keep the prosthesis in the fully flexed position
when putting it on or taking it off, and when not in use!
CAUTION
Sudden flexion of the DynamicArm. Especially if the
AFB compensation is set high and the lock is released
while the arm is in a horizontal or vertical position, the
DynamicArm can flex suddenly. A sudden flexion of
either the forearm or humeral section may also occur
while working with the prosthesis when it is taken off.
This may result in injury!
19 Instruct the patient about this danger!
Position 1
Minimal 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 compensa-
tion, and the elbow keeps flexed.
Position 4
Reduced compensation until flexion stop.

Humeral Rotation Feature
The humeral rotation turntable has integral stops (± 80°)
to block extreme movements. Turntable friction is eas-
ily adjusted by turning the external adjustment screw,
using a coin or similar object.
