3.2 All Instructions for Your Safety
DANGER
Potential Trac Accident Due to Limited Driving Ability
Gather information about all issues concerning safety and security and potential dangers, e.g.
unintentional locking of the system joint, before driving a motor vehicle with orthosis.
DANGER
Danger to Life Due to Improper Handling of the Charger
When using the charger, please respect the information of the manufacturer in order to avoid
short circuits and surges. You will find the corresponding patient information in your remote
control case.
WARNING
Risk of Falling Due to Loosely Attached Cover Plate
Do not secure screws for the system joint on your own. Consult your orthotist about the main-
tenance intervals to be respected.
WARNING
Risk of Falling Due to Improper Handling
Have your orthotist inform you about the correct use of the system joint.
- Avoid contact with moisture and water.
- In Auto mode, always make the first step with the leg with orthosis.
- Disable the permanent unlock function if you no longer wish to use it.
- When changing the mode with the orthosis, make sure to stand safely.
WARNING
Risk of Falling Due to Improper Shoe
Wear a shoe to which your orthosis is adjusted in order to avoid joint dysfunction.
WARNING
Risk of Falling Due to Orthosis Adjustments
If you notice any changes on the orthosis (e.g. loosely attached joint components or changed
spring forces), immediately contact your orthotist.
WARNING
Risk of Falling Due to Improper Cleaning
In order to avoid a failure of the lock function, clean the orthosis and the system joint as de-
scribed in this patient information. Do not grease the system joint on your own. If necessary,
consult your orthotist.

34
WARNING
Risk of Falling Due to Walking Incorrectly with Orthosis
Consult your orthotist about the correct use of your orthosis and the particularities of the
system joint. If necessary, we recommend a physiotherapeutic gait re-education.
WARNING
Risk of Falling Due to Improper Maintenance
In order to avoid failure of the joint function and the electronics, let only a trained orthotist
check your orthosis.
WARNING
Risk of Falling Due to Damages to the Orthosis
Avoid damage to your orthosis and to the integrated electronics (e. g. due to shocks, knocks and
fall). If the orthosis, nevertheless, is damaged, switch your orthosis into Lock mode and contact
your orthotist as soon as possible.
WARNING
Risk of Injury Due to Improper Handling of the Batteries
In order not to damage the batteries being used and, therefore, not to cause failure of elec-
tronics, avoid improper handling of the batteries:
- strong heat (e.g. fire),
- knocks and shocks as well as
- contact with high humidity and water.
CAUTION
Threat to Environment Due to Improper Disposal of the Batteries
Never dispose of batteries with the residual waste so that toxic substances are not released
into the environment. Dispose the batteries properly.
NOTICE
Limitation of Joint Function Due to Electromagnetic/Magnetic Field
Please note that, while using the orthosis, an electromagnetic and magnetic field (e.g. MRI)
can lead to joint dysfunction.
NOTICE
Damages to Batteries Due to Improper Handling
Ensure the correct use of the batteries in order to avoid a short battery lifespan and joint
dysfunction. Concerning the batteries, make sure:
- to use them with the delivered charger according to the information of the manufacturer;
- to use and to charge them (fully) in pairs;
- to use them only at ambient temperatures from -20 °C to 45 °C;
- to use only undamaged batteries (without leakage of substances/liquids) and
- not to allow the batteries to come into contact with metal objects, humidity and water (use
the battery box).
Pay attention to the battery status indicator. If the batteries are not charged in time or are
unexpectedly empty or you do not have them at hand, you can also use standard AA batteries
for your orthosis.

35
NOTICE
Damages to Controller and Remote Control Due to Improper Handling
Ensure the correct use in order to avoid joint dysfunction. Avoid:
- to open the controller and the remote control as well as
- using them in areas where radio waves are forbidden (e.g. in planes, hospitals). Ask the
responsible sta on-site about using the controller and remote control.

36
4. Application
The NEURO TRONIC system knee joint is exclusively for use for orthotic fittings of the lower extremity. It must
be handled by a professionally trained user.
Every mechanical joint influences the orthosis' function and thus also the function of your leg. All FIOR &GENTZ
system joints were developed for everyday life activities such as standing, walking and running but not for
extreme loads due to sports such as climbing and parachuting. Depending on the type of orthotic fitting and
your individual physical abilities, driving a motor vehicle safely should be guaranteed. This is subject to national
laws and checked by authorised medical bodies. It is recommended to modify the motor vehicle to your special
needs (e.g. automatic transmission) so that the driving ability is given even without a functioning orthosis.
5. Introduction
You have received from your orthotist an individually produced orthosis with the high quality FIOR &GENTZ knee
joint system NEURO TRONIC. This knee joint system is also available with Bluetooth® technology.
The NEURO TRONIC knee joint system consists of the following articles (fig. 1):
NEURO TRONIC system knee joint;
NEURO TRONIC component set including controller, optionally without Bluetooth including exchange-
able batteries or with Bluetooth including exchangeable batteries or an integrated lithium-ion battery;
NEURO TRONIC remote control for the patient, optionally without Bluetooth including
microprocessor-controlled quick charger or with Bluetooth including microprocessor-controlled
quick charger or USB charging cable and app NEURO TRONIC User;
NEURO TRONIC multi-purpose device for the orthotist, with Bluetooth and app NEURO TRONIC Expert.
The system knee joint and the controller are mounted to your orthosis. The orthotist uses the multi-purpose
device in order to adjust the orthosis. You need the remote control for handling the ortosis. Complementary, you
can use the app NEURO TRONIC User.

6.1 Joint Functions
The NEURO TRONIC system knee joint is an automatic joint and provides four joint functions:
1. basic function at delivery status in Auto mode (see paragraph 6.1.1);
2. alternative function in Lock mode (see paragraph 6.1.2);
3. alternative function in Free mode (see paragraph 6.1.3);
4. alternative function in every mode (see paragraph 6.1.4).
6.1.1 Basic Function in Auto Mode
The controller of the orthosis has motion sensors that detect the movement and position of your lower leg.
Locking
The motion sensors register when you are standing with the orthosis and the NEURO TRONIC
system knee joint (fig. 4) is locked. In terminal swing, when your leg loses speed and is right
before initial contact (fig. 5), the electronics lock the system knee joint. The solenoid shuts
off and the pressure spring pushes the plunger upwards, which causes the locking pawl to
mesh into the toothing of the toothed ring (fig. 6).

Unlocking
The motion sensors register when you are walking with the orthosis and
the NEURO TRONIC system knee joint is unlocked. When you are stret-
ching the leg in terminal stance,the system knee joint is unlocked and is
therefore free moving in swing phase (fig. 5). The solenoid turns on and
generates an electromagnetic field, which causes the plunger to retract
magnetically against the spring force, while gravity causes the locking
pawl to fall downwards out of the toothing of the toothed ring (fig. 7).
6.1.2 Alternative Function in Lock Mode
In Lock mode, the NEURO TRONIC system knee joint is a locked joint
to provide motion control. It is permanently mechanically locked in a
determined position.
6.1.3 Alternative Function in Free Mode
In Free mode, the NEURO TRONIC system knee joint is a free moving joint
to provide motion control. It is limitedly free moving up to a determined
position.
If you want to drive a car or bicycle in this mode, it is recommended to permanently unlock the NEURO TRONIC
system knee joint with the lever (see paragraph 6.1.4).
6.1.4 Alternative Function in Every Mode
The NEURO TRONIC system knee joint can be permanently unlocked mechanically
with a lever, for example for activities such as driving a car or bicycle. In this mode
it is guaranteed that the NEURO TRONIC system knee joint does not lock unin-
tentionally, e.g. at strong shocks or when the battery is empty/batteries are empty.
To do so, first set the orthosis into Free mode with the remote control/app, then
unlock the system joint manually with the lever by setting the lever to F. The
NEUROTRONIC system knee joint also remains unlocked if you select another
mode (e.g. Auto) with the remote control/app since the lever blocks the locking
pawl, which, therefore, cannot mesh into the toothing.
In order to change the system joint’s mode as usual with the remote control/app,
the lever must be set to the dot (fig. 8).
In terminal stance and pre swing the system joint is free moving in preparation to the subsequent
swing phase. If, contrary to expectations, you put weight on the leg with orthosis, the system joint
does not lock. However, you can take advantage of this fact for sitting down. You should practise
that in the physiotherapeutic gait re-education.

6.2 The Remote Control
You can select the mode on your orthosis with the remote control. You cannot change the mode while walking.
Therefore, make sure to stand safely when changing the mode with the orthosis. After a mode change, check
if the desired mode is selected. Every time you press a button of the remote control, the LED blinks shortly.

mode and the battery quality.
2 Auto button In Auto mode, the system joint locks and unlocks
automatically in the corresponding gait phases.
3 Free button In Free mode, the system joint is permanently
free moving.
4 Lock button In Lock mode, the system joint is permanently
locked.
Since the remote control is an electronic device, it is important to use it properly (see safety instructions). If
your remote control does not work as usual, do not try to open it. Contact your orthotist.
6.3 App NEURO TRONIC User
The app is intended to complement your remote control. It offers the same range of
functions.
If your orthosis is equipped with a controller with Bluetooth, you can operate the
orthosis either with the remote control with Bluetooth and/or with the app via your
smartphone/tablet (fig. 9) or your Apple Watch* (fig. 10). However, for that you need at
least Bluetooth 4.0. You can download the free app via the Play Store for the Android
operating system (from version 5.0) or via the App Store for the iOS operating system
(from iOS 10). The app offers the same functions that you can use with the remote
control (see paragraph 6.2).
* Apple Watch is a trademark of Apple Inc., registered in the U.S. and other countries.
If you want to save battery power in this alternative function, you have to press the Lock button
on the remote control/app after having set the lever to F. Thus, the solenoid turns off. The orthosis
remains unlocked.
Since the remote control/app is connected with the controller of your orthosis,
it controls only your orthosis. Other remote controls/apps have no influence
on your orthosis.

6.5 Manual Mode Change
The controller has a MODE button to use the orthosis e.g. if you have lost
your remote control or you do not have your smartphone/tablet at hand or
you are not allowed or not able to use them.
On a controller with exchangeable batteries, you see a small opening in
the upper part of the battery compartment marked with MODE (fig. 11).
fig. 11

43
The opening is about 1cm deep. You can select the mode on the orthosis by
pressing a pointed object (e.g. a paper clip) into the opening.
On a controller with an integrated lithium-ion battery, the rectangular
MODE button is located under the cover above the micro-USB port (fig. 12).
Depending on the already selected mode, it can be set in the following
order: Auto, Free and Lock. This switch is particularly important when you
are travelling by plane. Due of the special regulation of using electronic
devices in aircrafts, you are not allowed to use the remote control as well
as Auto mode during the flight phases, takeoff, approach and landing. Switch your orthosis into Free or Lock
mode before these flight phases. You are allowed to use again the remote control/app during flight and after
landing. If you have to change the mode during one of the mentioned flight phases, only use the MODE button.
7. Connection between Controller and Remote Control/App
At a controller and remote control without Bluetooth, your orthotist has to establish the connection.
If you have a remote control with Bluetooth, you can directly connect it with a controller with Bluetooth.
Proceed as follows:
1. Press the MODE button at the controller. A short beep is emitted. Keep the button pressed until a second,
longer beep is emitted after about 6-10 seconds.
2. Press the Auto and Lock button of the remote control at the same time for about four seconds. The LED
blinks yellow.
3. If the connection to the controller has been successfully established, the LED at the remote control blinks
green. If establishing the connection has failed, it blinks red.
If you would like to adjust the controller via the app NEURO TRONIC User, you need a controller with Bluetooth.
Use the app menu and select the corresponding menu item to establish a connection. Follow the instructions
in the app.
7.1 Controlling Two Orthoses
If you are wearing two orthoses with a NEURO TRONIC knee joint system, you can decide to connect the con-
trollers of both orthoses with one or two remote controls. If you activate two remote controls, you can change
the modes separately for each controller/orthosis. If you activate only one remote control, the modes of both
controllers/orthoses are changed simultaneously.
If the orthoses are equipped with controllers with Bluetooth, the modes can be switched separately or at the
same time for the two controllers/orthoses with the app NEURO TRONIC User.
fig. 12
The MODE button can only be used as long as the batteries are not completely discharged. When the
batteries are completely discharged, you can only use the Lock mode.
As soon as the controller is paired with a remote control and/or app, the orthosis can be controlled
with them as the pairing is saved. Other remote controls/apps have no influence on the orthosis.

44
8. Checking the Connection between Controller and Remote Control
Due to signals of the controller with battery compartment as well as of the remote control, you will be informed
if your remote control is connected with the controller. The LED at the remote control indicates that the remote
control and the controller communicate with each other. There are different signals for a connection with one
or two controllers.

9. Checking the Connection between Controller and App NEURO TRONIC User
In order to operate the orthosis via the app, Bluetooth must be permanently switched on and the app must be
open in the foreground. The signalling on the controller is the same as when connected to the remote control.
Use the menu of the app and select the desired menu item to connect to one or two controllers. Follow the
instructions in the app.
An orthosis can only be operated with one app at the same time because there is a connection between the
controller and the app. Other apps have no influence on the connected orthosis. You can continue to use the
remote control instead of the app when the controller is connected to the remote control and is not actively
communicating with the app. The app is intended to complement your remote control.

46
10. Checking the Battery Status
10.1 Indication of Battery Status on the Controller
If your controller has an integrated lithium-ion battery, you can see the battery status of the controller on the
remote control or in the app. Furthermore, the LED battery level indicator indicates the following light signals
for the battery status:
Light Signal

green The batteries are fully charged.
yellow The batteries are charging.
red 0.5 sec. The battery status is critical.
If your controller has exchangeable batteries, the LEDs on the controller blink briefly when you insert them. If
the LEDs do not blink, the batteries are perhaps wrongly inserted or they are fully discharged.
Soon afterwards, the LED battery status indicator on the controller shows one of the following light signals:

The signal sounds every minute because of the importance of a properly working orthosis. By pressing one of the
three buttons of the remote control, you can extend this period to ten minutes. The pause can be extended by
a further ten minutes by pressing the button again. If no button is pressed, the signal will sound every minute.
10.2 Indication of Battery Status on Remote Control/in the App
If you operate the orthosis via app, you can see the battery status of the controller(s) at any time in the app.
You can also check the status of the batteries in the controller(s) with your remote control. There are different
signals for a connection with one or two controllers.
In order to save energy, the battery status is not displayed in Lock mode.

10.2.2 Indication of the Battery Status for a Connection with two Controllers
If your remote control is connected with two controllers, the light signal on the remote control does not apply
automatically to both controllers but to that with the lowest battery. The battery status indicator on the controller
(see paragraph 10.1) allows you to determine whether the batteries of both controllers are affected or at which
orthosis you need to change the batteries.
Example: The LED of the remote control flashes red, after you have pressed one of the three buttons. The LED
battery status indicator of the controller of the right orthosis gives no light signal, which means that the battery
is full. The LED battery status indicator of the controller of the left orthosis briefly blinks three times red. The
batteries in this orthosis should soon be exchanged.
11. Energy Consumption
11.1 Useful Life of Batteries in Different Modes
Your orthosis consumes energy in all three modes, the fewest in Lock mode. If there are mounted two NEUROTRONIC
system knee joints to your orthosis (bilateral construction), both system joints are supplied with battery energy
from one controller. Therefore, the useful life of the batteries considerably shortens in contrast to a unilateral
construction (one NEURO TRONIC system knee joint mounted to your orthosis).
The use of the original charger and charging the original NiMH batteries or the lithium-ion battery to the maxi-
mum lead to the following average battery life at room temperature:
Battery Type Orthosis Auto Free Lock
exchangeable

unilateral 45 hours 45 hours
over 2 weeks
bilateral 24 hours 24 hours
lithium-ion battery unilateral 18 hours 42 hours
bilateral 8.5 hours 19 hours
