The product “12K100N=* DynamicArm” is referred to simply as the product/elbow joint below.
These instructions for use provide you with important information on the use, adaptation and handling of the
product.
Only put the product into use in accordance with the information contained in the accompanying documents sup
plied.
The product may not be transferred to the patient without prior instruction.
2 Product description
2.1 Design
1. Easy Plug
2. ON switch
3. Strap clamp
4. Charging receptacle
5. Pull cable (mechanical release)
6. AFB dial
7. Humeral rotation feature adjusting screw
2.2 Function
The product is a myoelectrically controlled elbow joint driven by an electric motor. It helps the wearer perform
everyday tasks in combination with other prosthetic components (see Page5).
A Li-Ion battery integrated into the product provides the energy required. The “646C42=V* ElbowSoft” software is
used for the patient-specific adjustment of the product.
If the elbow joint is off or the battery is depleted, the elbow joint can still be locked and unlocked in any position,
even when loaded, by means of the pull cable.
In new condition, the product can lift a load of up to 5kg. Once this load is exceeded, the joint will be locked. Flex
ion and extension are only possible again after the load is reduced.
2.2.1 Definition of terms
AFB (Automatic Forearm Balance)
AFB is a flexion assist in the form of a mechanical gear mechanism in the forearm of the elbow joint. The Automatic
Forearm Balance provides for harmonious movement control, free swing and reduction of energy consumption. It
stores the energy that is released when the arm is extended and uses this to assist with flexion. The degree of flex
ion assistance can be adjusted to the individual weight of the prosthetic forearm and to different clothing by means
of a dial.
The free swing of the forearm corresponds to the natural movement behaviour of the upper limb while walking.
After extension of the forearm, the vario-gear automatically decouples the forearm from the drive unit so it can
3DynamicArm 12K100N
Foreword

swing freely. The AFB slightly dampens the free swing, thereby making a close approximation of the forearm’s
physiological movement behaviour possible.
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
1. No function
2. Electrode
3. Electrode
4. Optional switch
The Easy Plug feature makes it simple to wire myoelectric prostheses.
The connecting cables of the electrodes and an optional switch are connected to the Easy Plug. Its interior cable
routing minimises the risk of cable breaks.
Forearm cable
The forearm cable establishes the electrical connection between the product,
electric wrist rotator and System Electric Hand or System Electric Greifer.
On delivery the forearm cable is rolled up in the forearm of the elbow joint. After
the forearm has been cut to its final length, the forearm cable can be pulled out.
INFORMATION
Do not pull out cables before cutting the forearm to length.
Lock
Releasing and locking the elbow joint is automated according to operating situations, the applied load and the con
trol signal generated by the patient by means of the electronically controlled locking drive.
The product has a load capacity of up to 230N in the locked state with a forearm lever length of 305mm. The lock
will slip under higher loads.
Mechanical release
With the product switched off or when the battery is drained, the elbow can be manually unlocked and locked
again with a slight pull on the unlock cable. In this way, the forearm can be brought into the desired position.
Mechanical release can also take place under load.

305–213mm possible
212–187mm not possible
6.1.2 Cutting to length
NOTICE
Do not pull the foam or cable protector cap out of the forearm under any circumstances before the forearm is cut
to length and before the lamination ring is glued in! Doing so will reduce the useable portion of the forearm!
If the cables were pulled out anyway, they have to be pushed back into the forearm and secured with the foam disc
before performing further work. The cables take up more space in the forearm as a result.

Preparation for use

INFORMATION
Cables pulled out before cutting to length
If the cables were pulled out before the forearm has been cut to length and the lamination ring has not been glued
in yet (for example after a trial fitting), the cables have to be pushed back into the forearm and secured with the
foam disc before performing further work on the forearm.
As a result, the cables take up more space in the forearm compared to the delivery condition from the factory. The
usable length of the forearm will be reduced.
Then the forearm can only be shortened to the following lengths:
• To a minimum of 230mm when using the 10S17 electric wrist rotator.
• To a minimum of 207mm when not using the 10S17 electric wrist rotator.
Proceed as described above to cut to length and glue in the lamination ring
INFORMATION
If the foam disc has been glued into place, the cables can be pulled out carefully through the slotted foam disc
using the hook.
6.3 Checking the symmetry
1) Connect prosthetic components to the forearm.
2) Check the symmetry using the 743L20=230 Ottobock LaserLine.
6.4 Sealing the prosthesis
Consult the enclosed technical information for the fabrication of the patient’s socket and cutting the forearm socket
to length.
1) After laminating the lamination ring, remove the
grease and any dirt.
2) Lubricate the groove, inner edges and thread of the
lamination ring with 633F30 special grease.
6.5 Plugging in the contact
1) Apply a generous amount of 633F11 silicone
grease to the connector contacts of the 13E219
control electronics.

17DynamicArm 12K100N
Preparation for use

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.
6.9 Adjusting the product
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.
6.10 Adjusting the humeral rotation feature
►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.

6.11 Wiring the product with the electric wrist rotator
1) The MyoRotronic cannot be combined with the
elbow joint. The MyoRotronic would be destroyed
when operating the elbow joint.
2) There are numbers for the plug contacts on the
plastic housing of the electric wrist rotator. These
numbers serve as orientation for connecting the
cables.
3) Attach the motor cable to one of the two contacts.
Connect two-pole receptacle to contact no. 3.
4) Connect three-pole receptacle to contact no. 2.
One of the three-pole connectors is marked with a
coloured dot.
5) If the two three-pole connectors are interchanged
when connecting them to the two contacts, no func
tion of the System Electric Hand or System Electric
Greifer is possible.
6) To secure the coaxial plug, insert the retaining ring
into the groove of the lamination ring using tweez
ers.
7) Then install the electric wrist rotator in the lamina
tion ring.
6.12 Wiring without electric wrist rotator
1) One of the two three-pole connectors is marked
with a coloured dot (arrow). The two receptacles
must not be interchanged!
