as adhesive tape) to reduce cable movement.

9
CAUTION
Proximity to sources of strong magnetic or electrical interference (e.g. theft prevention
systems, metal detectors)
Injury due to unexpected behaviour of the product caused by interference with internal data
communication.
►Avoid remaining in the vicinity of visible or concealed theft prevention systems at the
entrance/exit of stores, metal detectors/body scanners for persons (e.g. in airports) or other
sources of strong magnetic and electrical interference (e.g. high-voltage lines, transmitters,
transformer stations, computer tomographs, magnetic resonance tomographs, etc.).
►When walking through theft prevention systems, body scanners or metal detectors, watch
for unexpected behaviour of the product.
CAUTION
Electrode lifting off
Injury due to unexpected product behaviour as a result of uncontrolled activation of the pros
thesis component.
►Inform the patient that uncontrolled movement of the prosthesis component may occur if the
electrode lifts off.
CAUTION
Skin irritation due to inadequate cleaning of the product
Skin irritation due to contact with soiled electrode domes.
►Clean the product only as described in the section "Cleaning and care" (see page17).
CAUTION
Insufficient skin contact of the electrodes
Injury due to faulty control or malfunction of the product.
►The electrodes are to be placed on intact skin only and with as much electrode-skin contact
as possible.
►Use the different electrode dome heights to improve the skin contact.
►Make sure that skin contact of the electrodes continues to be given when carrying heavy
loads.
CAUTION
Insufficient space for electrode domes because distance is too small
Injury due to unexpected prosthesis behaviour.
►Make sure that the electrode domes do not touch each other. Reduce the number of elec
trode domes if necessary (e.g. if the arm is very thin).
►Watch the electrode contacts if the residual limb swings or moves.
►Use suitable dome heights according to the fit of the prosthetic socket.
CAUTION
Incorrect electrode settings due to muscle fatigue
Injury due to faulty control or malfunction of the product.
►The patient should take breaks during calibration.

10
CAUTION
Insufficient distance to HF communication devices (e.g. mobile phones, Bluetooth

6 Charging the battery
We recommend charging on a daily basis. If the device is not used for an extended period, the
battery charge level should be checked regularly and the battery recharged.
See the respective instructions for use for information on correct battery charging.
7 Preparing the product for use
7.1 Laminating instructions
The product can be positioned in the forearm socket.
7.2 Determine electrode position
INFORMATION
Depending on the residual limb and socket structure, the electrode domes may leave impres
sions in the patient's skin. Use the flat electrode domes in case of deep impressions in the skin.
Use the high electrode domes if there are no or only barely visible impressions in the patient's
skin.
Required tools
• Drill; twist drill ø5mm
The remote electrodes have to be positioned as follows:
1) Mark the position of remote electrode 1 below the ulna and 6-7 cm distal of the olecranon.
2) Extend the marking around the entire circumference of the prosthetic socket.
→This creates a circumferential line.
3) From the line, measure and mark 40 mm in the distal direction.
4) Extend the marking around the entire circumference of the prosthetic socket.
→This creates a second circumferential line.
5) Determine the positions of the remaining remote electrodes using the positioning gauge for
the O&P professional.
6) Mark the remote electrodes 2 - 8 on the proximal line (e.g. with an X).
7) Reflect the electrode positions to the distal line.
8) Drill through the prosthetic socket at the marked locations with a 5 mm bit.
9) For 2 of 8 electrodes, an additional hole has to be drilled for the reference potential contact.
INFORMATION: The hole for the reference potential contact can either be drilled
between the two electrode domes or in a position where little muscle activity is expec
ted.
The electrode dummies must be used to fabricate the outer socket. The battery dummies and Myo
Plus TR dummy must be positioned on the prosthetic socket according to the space require
ments. If desired, the remote electrodes can also be attached in the cavity between the outer and

12
inner socket. Fabricate the outer socket using the familiar technique. The "No Carbon Zone"
label can be applied to the Myo Plus TR dummy as an aid for the lamination of carbon sockets.
7.3 Inserting electrodes
CAUTION
Improper securing of the electrode domes
Injury due to product malfunction.
►Do not use thread locking compound (Loctite) to secure the electrode domes. Applying
thread locking compound forms an insulating layer that prevents transmission of the EMG
signals.
Required tools
• Lug wrench (7 mm)
included in delivery
1) Insert the dome nut into the prepared hole in the prosthetic socket from the outside.
2) Insert the dome of the remote electrode into the prosthetic socket from the inside.
The blue and green cables have to be positioned on the two marked lines.
3) Secure the remote electrodes and cables on the inner socket with adhesive tape or hook-and-
loop fastening strap.
4) Screw on the dome with the dome nut.
5) Hand-tighten the dome nut with the wrench.
INFORMATION: If the dome nut is over-tightened, the dome tears off at the predeter
mined breaking point. Use the supplied tools.
INFORMATION: The remote electrodes and wiring can be protected against moisture
and dirt with film or adhesive tape.
7.4 Installing the Myo Plus TR
The Myo Plus TR can be secured on the inner socket with adhesive tape or a hook-and-loop
fastening strap. To protect it against moisture, the Myo Plus TR can be covered with film or
adhesive tape.
Should the available space between the outer and inner socket be insufficient, a space must be
reserved during lamination of the outer socket (lamination dummy). Different electrode cable
lengths permit installation in the outer socket.
The following steps must be carried out to connect the electrode and Myo Plus TR:
1) Remove the cover caps from the required inputs.
2) Connect the remote electrodes to the Myo Plus TR.
Observe the correct assignment of the plug connections.
INFORMATION: Plug connection "A" must not be used.
INFORMATION: If fewer than 8 remote electrodes are installed, the plug connections
with the highest numbers are not used.
3) Secure the cables with the protection cap.
7.5 Establishing a connection
INFORMATION
The numbers on the plastic housing serve as orientation for connecting the cables.
INFORMATION
The connection between the Myo Plus TR and the respective component is identical for a pros
thesis on the right and left side. The prosthesis side and rotation direction are set in the Myo
Plus app.
