Otto Bock DynamicArm Plus Instructions For Use Manual page 37

The product does not consume electrical energy during the free swing. A short muscle signal to flex the product
ends the free swing.
Humeral rotation feature
The humeral rotation feature is an upper arm rotation joint with bilateral stops. It is used for rotation of the forearm.
The resistance of the humeral rotation feature can be changed using the adjusting screw.
Easy Plug
The Easy Plug feature makes it simple to wire myoelectric prostheses.
The connecting cables of the electrodes, switches and batteries are connected to the Easy Plug. Its interior cable
routing minimises the risk of cable breaks.
In the DynamicArm Plus, only the 13E219 control electronics are connected in the area of the elbow ball. All other
plug connections have no function.
