The device uses low-frequency electric currents for therapeutic purposes. The induced
electric pulses, their intensity, frequency and frequency width are controlled by the
respective application programme. By means of adhesive electrode pads applied on the
skin, the electric pulses are transmitted to the nervous system and the muscles.
The current flows from the positive (+) adhesive electrode to the negative (-) adhesive
electrode. For the purpose of pain treatment, the delivery of pain to the central nervous
system is influenced during the application of a TENS therapy. The user does no longer
perceive the pain at all or perceives the pain to a limited extent only. The two TENS
stimulators A and B (correspond to channels 1 and 2) can be used independently of one
another on two different parts of the body. Thus, you are able to treat two areas of pain
at the same time. Using the remote control, the intensity of the TENS stimulators A and B
can be comfortably set either individually for each of the two TENS stimulators or
simultaneously for both TENS stimulators. As an alternative, the intensity can also be set
separately on each of the two TENS stimulators A and B. The TENS therapy activates the
body's own pain suppressing sequences in the central nervous system, inhibiting the
transmission of pain impulses to the brain.
The TENS therapy with low frequency and high intensity (muscle twitches occur in the
area of the electrodes) activates the body's own pain regulating systems in the brain. As
a result, the body's own messengers (e.g. endorphins) which suppress the pain and can
cause a general improvement of the blood circulation are increasingly released.
2.2 Information concerning the TENS therapy
The radio TENS device TGS 440 is an electro-stimulation device. To this end, an
electric current is transmitted through the skin to the nerves.
"TENS" means "transcutaneous electric nerve stimulation". Using this convenient and
comfortable radio TENS device, certain parts of the body are stimulated in a targeted
manner with the effect that pain and symptoms can be relieved significantly.

3.9.2 Avoid any contact with the adhesive electrode pads during the therapy. Under
certain circumstances, touching the electrodes results in a short circuit involving
an excessive current density. This excessive current density might cause burns
and injuries!
Please remove the protective foil before applying the adhesive electrode pads on
the skin. The adhesive strength of the electrode pads depends on the condition of
the skin, storage and number of therapy sessions. If the adhesive electrode pads
do no longer stick completely on the skin surface, they must be replaced by new
adhesive electrode pads. The adhesive electrode pads must lie completely flat
against the skin in order to avoid locally high current densities which might result
in skin burns. After the application has been completed, stick the adhesive
electrode pads back on the protective foil and keep them in a protected
environment to ensure that they cannot dry out. Thus, their adhesive strength
can be maintained for a longer period of time.
Each person reacts differently to an electric nerve stimulation. If the therapy is
not successful, please seek medical advice.
The adhesive electrode pads can also be connected to the TENS stimulators or
disconnected from them using the press stud connection.
Carefully remove the adhesive electrode pads from the TENS stimulators in order
to prevent them from being damaged.
Only connect the adhesive electrode pads to the TENS stimulators if they have
been switched off!
Before using the adhesive electrode pads, the areas of the skin on which you wish
to apply them must be thoroughly cleaned and dried. These areas of the skin
should be greaseless and clean.
Using the radio TENS device may result in skin irritations. If skin irritations such
as redness, blisters or itching occur, you should no longer use the radio TENS
device and seek medical advice! Do not apply the adhesive electrode pads
permanently on the same part of the body, as this can lead to skin irritations.
If you wish to reposition the adhesive electrode pads during the therapy, make
sure that you switch off the TENS stimulators first.
The adhesive electrode pads included in the scope of delivery may only be
connected to the radio TENS device TGS 440. Please ensure that the TENS
stimulators are always switched off when applying or removing the adhesive
electrode pads.
For the radio TENS device TGS 440, only use the adhesive electrode pads

positioned directly next to the heart region in order to prevent current flowing
through the heart region.
The adhesive electrode pads must not be applied in such a manner that the
current can directly flow through the brain, e.g. on both templates.
Do not apply the adhesive electrode pads on the following parts of the
body: a. on and in the mouth, b. eyelids, c. front neck area, d. larynx,
e. throat area, f. carotid artery, g. heart region, h. genitalia (genital
organs: penis, testicles, ...), i. fingers, j. pacemakers.
The adhesive electrode pads must not be applied on parts of the body with skin
inflammations or open and fresh wounds or fresh scars.
4.1 Areas where the adhesive electrode pads must
not be applied
Please ensure that the painful part of the body is enclosed by the positions of the
electrodes during a TENS therapy. For an aching group of muscles, you should
apply the electrodes in such a manner that the affected muscles are also enclosed
by the electrodes.
Do not pull the TENS stimulators if you wish to remove the adhesive electrode
pads from the skin! To this end, lift the adhesive electrode pad in the area of the
arrow with the "PULL" imprint and remove it carefully from the skin. Please make
sure that you do not touch the adhesive surfaces with your fingers. Afterwards,
stick the adhesive electrode pads back onto the protective foil and store them in a
cool and dry place.
The adhesive electrode pad consists of two individual electrodes (+ (positive) and
- (negative) pole) which are separated by a white strip in the middle. The
distance between the electrodes has already been defined by the design and,
thus, cannot be changed.
The adhesive electrode pads must not be resized, e.g. by cutting off parts.
Do not use any adhesive electrode pads of an electrode size smaller than 90x57
mm; otherwise, too high a current density can flow and injuries may be caused.
Smaller electrodes falling below a minimum size of 90x57 mm may only be used
if approved by the doctor in charge. In this respect, it is absolutely necessary to
observe the safety instructions of the manufacturer of the respective adhesive
electrodes.
In order to position the adhesive electrode pads correctly, use the information as
well as the figures on page 20 and 21 for TENS therapies intended as application
examples as guidance.
Each person reacts differently to an electric nerve stimulation. The positioning of
the adhesive electrode pads might thus deviate from the standard positions. If
the therapies are not successful, please consult your doctor as to which
positioning techniques are most suitable for you.

Insert two 1.5 V batteries (type AAA) observing the correct
polarity (+ (positive) and - (negative) pole) in the remote
control and in the TENS stimulators (see Figure 7 and
description in Chap. 7.0 on page 13-14).
Step 1
Prior to starting a therapy session, carefully clean the skin
areas in the application area using water and soap and dry it
well afterwards (see Figure 6).

Step 8
The programme sequence and the application time of 30
minutes are permanently set and cannot be changed. After
the application time has expired, the TENS stimulators are
switched off automatically and the green LEDs go out. If you
wish to stop the therapy session before the application time
has expired, you can press the ON/OFF key on the remote
control. The current therapy session is then stopped
immediately and the TENS stimulators are switched off.
Afterwards, carefully remove the adhesive electrode pads from
the skin. To this end, lift the adhesive electrode pad in the area
of the arrow with the "PULL" imprint and remove it carefully
from the skin. Please make sure that you do not touch the
adhesive surfaces with your fingers. Afterwards, stick the
adhesive electrode pads back onto the protective foil and store
them in a suitable place under cool and dry conditions.
Attention! Never remove the adhesive electrode pads from
the skin while the device is still switched on!
Step 7
Increase the output intensity by pressing the A (+) or B (+)
keys on the remote control (see Figure 14) or on the TENS
stimulator A or B (see Figure 15) according to your individual
needs. Every time you press one of the (+) keys, the output
intensity of the respective TENS stimulator is increased by one
level. If both TENS stimulators are used, you can increase the
intensity setting for both TENS stimulators A and B
simultaneously (both at the same time) by pressing the A/B
(+) key on the remote control.
By using the A (-) or B (-) keys on the remote control (see
Figure 16) or on the TENS stimulator A or B (see Figure 17),
you can reduce the intensity of the TENS stimulators. Every
time you press one of the (-) keys, the output intensity of the
respective TENS stimulator is reduced by one level. If both
TENS stimulators are used, you can reduce the intensity setting
for both TENS stimulators A and B simultaneously (both at the
same time) by pressing the A/B (-) key on the remote control.
Step 6
Now, press the ON/OFF key on the remote control first in
order to switch it on (see Figure 12). The green LED flashes
briefly for confirmation and goes out again. Now, switch on the
TENS stimulator Aor B(or both TENS stimulators) by pressing
once on the (+) key of the respective TENS stimulator. The
green LED on the TENS stimulator lights up (see Figure 13).

PLEASE NOTE: If the green LED on a TENS stimulator does no longer flash during the
therapy session, please check if the adhesive electrode pad has full contact with the skin.
PLEASE NOTE:
During operation, the green LEDs of the TENS stimulators flash slowly; however, every
time one of the (+) or (-) keys of the remote control is pressed, they flash rapidly. Rapid
flashing indicates that the device receives a control pulse from the remote control. Every
time a key is pressed on the remote control, the green remote control LED flashes in
addition to this. If you press one of the (+) keys on one of the TENS stimulators during
the therapy session, the output intensity is increased by one level. If you press one of
the (-) keys on one of the TENS stimulators during the therapy session, the output
intensity is reduced by one level. Every time one of the (+) or (-) keys on one of the
TENS stimulators A or B are pressed, the green LEDs of the TENS stimulators flash
slowly.
Setting the output intensity of the TENS stimulators
In order to increase the output intensity, the (+) keys on the TENS stimulators as well
as the (+) keys on the remote control are used, where the output intensity of the TENS
stimulators can be increased individually using the A (+) or B (+) keys or
simultaneously using the A/B (+) key.
In order to reduce the output intensity, the (-) keys on the TENS stimulators as well as
the (-) keys on the remote control are used, where the output intensity of the TENS
stimulators can be reduced individually using the A (-) or B (-) keys or simultaneously
using the A/B (-) key.
Functions of the green LEDs of the TENS stimulators
LED lights up: Standby mode / The device is ready for operation
LED flashes: Operating mode / The adhesive electrodes have
been applied and the device is in operation
LED flashes quickly: Receive mode / The device receives the pulses
from the remote control
LED out: "OFF" mode / The device has been switched off

Switching off the TENS stimulators
2. Press the ON/OFF key on the remote control. The green LED of the remote control
flashes and the TENS stimulators are switched off immediately.
1. In the standby mode (green LED lights up constantly), you can switch off the TENS
stimulators by pressing the (-) key on the TENS stimulator.
The permanently set application time is 30 minutes. The TENS stimulators are switched
off automatically after this time has expired. However, you can also switch off the TENS
stimulators manually at any time as follows:

PLEASE NOTE: If the green LED on a TENS stimulator does no longer flash during the
therapy session, please check if the adhesive electrode pad has full contact with the skin.
However, switching on and off as well as increasing and reducing the output
intensity can also be carried out by directly pressing the (+) and (-) keys on the
TENS stimulators (channel 1 = TENS stimulator A, channel 2 = TENS
stimulator B).
The radio TENS device TGS 440 can be controlled comfortably using the remote
control included in the scope of delivery. Using this remote control, the output
intensity of the TENS stimulators Aand Bcan be increased and reduced both
separately (individually) and simultaneously (both at the same time) and the
stimulators can also be switched off by pressing a single key.
10.0 Remote control
PLEASE NOTE:
There are 20 output intensity levels for the TENS stimulators. Every time one of the (+)
keys on the remote control or on one of the TENS stimulators is pressed the output
intensity is increased by one level. For safety reasons, a fast forward by pressing the key
and keeping it pressed is not possible; thus, increasing the output intensity too fast can
be avoided. If you increase the output intensity on one of the (+) keys on the remote
control, the increase by one level is indicated with the green LEDs on the TENS
stimulators flashing fast. If this fast flashing of the LEDs of the TENS stimulators no
longer occurs despite pressing one of the (+) keys on the remote control, the highest
output intensity has already been reached.
Every time one of the (-) keys on the remote control or on one of the TENS stimulators
is pressed the output intensity is reduced by one level. A fast rewind by pressing the key
and keeping it pressed is not possible. If you reduce the output intensity on one of the
(-) keys on the remote control, the reduction by one level is indicated with the green
LEDs on the TENS stimulators flashing fast. If this fast flashing of the LEDs of the TENS
stimulators no longer occurs despite pressing one of the (-) keys on the remote control
and the LEDs light up constantly, the lowest output intensity has already been reached. If
you then press the (-) key on one of the TENS stimulators, this TENS stimulator is
switched off and the green LED goes out.
