Mechanical Release; On / Off Switch - Ottobock DynamicArm 12K100N Instrucciones De Uso

6.4 Lock
The DynamicArm is released and locked automatically by means of an electronically controlled lock motor, de-
pending on the situation of operation and on the load applied as well as on the control signal generated by the
patient.
In the locked state, a new DynamicArm has a load capacity of approx. 230 N (this value may decline slightly
over the course of several years due to wear). The lock will slip under higher loads. In case of higher loads,
the lock will slip through.

6.4.1 Mechanical Release

With the DynamicArm turned off or with a depleted battery, the elbow joint can be locked and unlocked
mechanically by actuating the cable control with a constantly low force, even when loaded.
6.5 Free Swing
The forearm shows a natural movement when swinging freely during walking. After forearm extension, the
Vario gear automatically uncouples the forearm from the motor thus enabling the forearm to swing freely. The
Automatic Forearm Balance feature (refer to 6.1) slightly dampens swinging, resulting in a quite natural move-
ment of the forearm.
During free swinging, the DynamicArm does not require any electric power. A short muscle signal generated
for flexing the DynamicArm stops the free swinging.
6.6 On / Off Switch
To turn the DynamicArm on and off, press the on/off switch (arrow).
The DynamicArm confirms turning on with a sound signal and a
single, short vibration. The patient is recommended to turn off the
DynamicArm during longer periods of passive use in order to make
the battery's capacity last longer.
6.7 Vario Gear
The Vario gear is an electromechanical, infinitely variable transmis-
sion serving the dynamic flexion and extension of the forearm. The
speed, acceleration and force automatically adapt to the patient's
activity depending on the control signal, load and flexion angle.
6.8 Axon-Bus
Axon-Bus stands for Adaptive exchange of neuroplacement data. The Axon-Bus is an innovation by Ottob-
ock for the field of exoprosthetics: a data transmission system, derived from safety-relevant bus systems from
the aviation and automobile industries. For the user this means more safety and more reliability because of
a considerably reduced sensitivity to electromagnetic interference in comparison with conventional systems.
7 Final Assembly of the DynamicArm
This section requires that the finished socket, which has been properly adapted to the patient with integrated
lamination ring, is on hand. This socket must be fabricated in conformity with the Ottobock certification train-
ing course and with the 646T3=3.3 Technical Information "Plaster Cast and Lamination Instructions".
Before using the DynamicArm, please read these Instructions for Use thoroughly! Please pay special attention
to the safety instructions!

CAUTION
Final assembly. False signals could cause uncontrolled
movement of the DynamicArm when switched on!
Do not switch the DynamicArm on during final assembly.
After laminating the lamination ring, remove the grease
and any dirt. Lubricate the groove, inner edge and thread
of the lamination ring with 633F30 Special Grease
