8. This device is designed for indoor use only. Do not expose it to rain or humidity.
9. Caution should be used when treating areas of the skin that lack normal sensation (e.g. diabetic
patients). Note: watch out for skin irritations. Pause the treatment if necessary.
10. High currents do not lead to a more successful treatment, but can lead to skin irritation
instead. The current strength should be adjusted to the comfort of the patient. In cases of skin
irritation, stop the treatment and seek advice from your doctor.
11. If the treatment feels uncomfortable, reduce the current strength to a comfortable level or
stop the session.
12. If the treatment is ineffective or unpleasant, discontinue the sessions and seek advice from
your doctor.
13. Before operation, the patient must sit still and all cables must be plugged in firmly.
14. The mains plug is specified as a part of this medical equipment. Only use the adaptor supplied
by the manufacturer.
15. Do not submerge the device in water.
16. Dropping the device may cause damage.
Side effects / accompanying symptoms
• Skin irritations are one possible side effect of the intended usage. The treatment should be
stopped until the cause of the irritation can be determined.
• You will perceive every treatment differently. For this reason, the milliampere value should only
be used as a rough guidance. The current strength should be adjusted according to your personal
comfort level.
• Iontophoresis treatment stimulates the circulation, so a harmless reddening of the skin after the
treatment may occur.
• During the treatment you may experience tingling or stinging sensations. In this case, you should
reduce the current strength to a comfortable value.
• As a consequence of the treatment, the skin will become increasingly drier.
• If the treatment leads to skin that is too dry, chapped or cracked, stop the treatment and consult
your doctor.

Structure and basic functions of the DE20

8
EN SweatStop® DE20
After the predefined treatment time of 20 minutes, the current flow will be interrupted auto-
matically. The text „treatment over“ will appear on the display. To switch off the device, turn the
button (1) back until it locks into place with a click.
The treatment time of 20 minutes begins once the circuit is first closed (displayed value > 0,00) and
will not be started anew if the circuit is momentarily interrupted to make adjustments.
2. Diverter for type of current
You may either choose direct current (DC) or pulsed current (PC). In “pulsed current” mode, the
ratio between pulse and pause is 1:1. This means that the efficient PC value is nearly half of the
displayed current value. Due to its decreased percentage of direct current, the pulsed current
allows more precise increments (5 mA PC is equivalent to 2,5 mA DC). Due to the interruptions in
the current, pulsed currents feel more comfortable for some patients.
3. Outlet sockets for electrodes
Two outlets: “Red“ - Anode (+) and “Black“ - cathode (-). Plug in the cables according to their
colours to connect the device with the electrodes. Change the polarity each time you start the
therapy, unless otherwise recommended by your doctor. The pole reversal can be carried out by
plugging the red cable into the black socket and the black cable into the red socket.
4. LED indicator “weak battery”
When this yellow LED lights up, it indicates that the accumulators are weak and must be re-
charged soon. You will be able to conduct 2 more treatment sessions before needing to recharge
the accumulators.

1. On / Off switch with current controller
To start the device, switch on clockwise until you hear a click.
Continue turning to control the amperage: turn clockwise to increase the value, anti-clockwise to
lower it.
This function is only available when the electric circuit is closed. When the circuit is interrupted,
the display will show “0,00” until the circuit is closed. Then, the current will slowly be raised until
it reaches the selected value.
The values 1-10 denote 10-100 % of the maximum value: in direct current mode, the maximum
value is 20 mA; 30 mA for pulsed current mode.

5. Digital display
During normal usage, the display shows the current value measured in mA (milliampere), as well
as the chosen current type (PC or DC). Additionally, it shows messages such as “treatment over”.
6. LED indicator “empty battery”
When this red LED lights up, it indicates that the accumulators are empty. You will have to re-
charge the accumulators before being able to use the device again.
7. Charging socket
The charging socket is located on the right side of the device (7). You may only use the supplied
charger, since it is adjusted to the accumulators built into the device. Connecting the device to the
wrong charger may lead to severe damage.
If the DC plug of the charger is inserted, the circuit will be interrupted and the device will be
deactivated.
8. Battery compartment
The device has a battery compartment (8) for four rechargeable
batteries / accumulators of the cell type LR (Baby / C). 4 NiMH accumulators are part of the delivery
scope. The charging duration depends on the capacity of the batteries and the charger – new cells
(standard equipment, 4x 2500 mAh) take approximately 11-12 hours to charge.
9. Code control
The number of all completed treatments will be saved. This code status has replaced the “therapy
diary” in order to offer an alternative proof for a regular trial phase to health insurances.
Trial phase under prescription by health insurance
Code status
Many health insurances want to make sure that the device is actually
needed before they take over the costs. Often, a therapy diary or the
questionnaire provided by AAM (including code) is used as proof of
the therapy sessions. The code status indicates the number of treat-
ments you conducted. By demand of certain health insurances, the
number of completed sessions was coded to impede a possible deception. In order to read the
code status on the display, insert a pointy object, e.g. a screwdriver (2-3 mm in diameter) into the
hole on the left side (9)* to press the code switch. Keep it pressed down and switch on the device
– after a few moments, a four-letter figure will appear on the display. The code switch can now
be released.
*Insert horizontally if you own the version in the etui; insert slantwise from above if you own the version in the plastic case.

Safety features
• Anti-overtreatment
As a result of a successful treatment, the electric resistance of the skin rises up. To avoid an over-
treatment, the system monitors the conductivity of the skin. The displayed message “max” signals
that the predefined resistance has been met. If a second, higher limit is reached, the system will be
locked and won’t even start. Since these limits have been adjusted to the “average patient“, they
may not fit your individual situation.
If the hyperhidrosis is not relieved and the device won’t start due to the protective function, please
don’t hesitate to contact us so that we can find an individual solution for your situation.
• Maximum current strength
The current strength is controlled by the device and cannot be increased above the maximum
values of 20 mA (direct current - DC) and 30mA (pulsed current – PC). To give you the best possible
feedback, the display always shows the real current value.
• Disconnecting the device from the current supply (240V/ 110V)
When the DC plug of the charger is plugged into the charging socket of the device, the treatment
cannot be conducted. The DC plug disconnects the electric circuit. For this reason, the treatment is
only possible when the charger is disconnected.
• Protection against accidental change of current type
Switching between pulsed current and direct current is impossible during the operation of the
device. An accidental change between the current types cannot occur during the treatment. When
the device is started, the position of the button is saved and will be upheld until the end of the
treatment session even if the current type is changed.
• Anti pasture fence effect
To avoid electric shocks by the adjusted voltage when submerging the hands or feet, the controls
will only be started once the current is closed (= hands or feet are submerged). The current will
now rise gradually. If the circuit is interrupted during the treatment, the value will be reset to zero.
Once the treatment is continued, the current will gradually rise to the chosen value.

SweatStop® DE20
Application
Basics
Tap water iontophoresis is used for the temporary relief of the hyperhidrosis affecting the palms
of hands and feet and the underarms. The chances to reduce the perspiration to a normal level
without damaging the perspiratory glands are very high. This effect is achieved by running an
electric current (constant or pulsed) through the affected body parts to accustom the cells to
electric stimulation. As a result, the sweat glands will be slower to react to their own stimulation.
Since the glands are “only” familiarised with electric stimulation, their original condition will
return relatively fast once the treatment is discontinued!
As a rule of thumb, conduct a daily initial therapy until you observe a significant effect (without
skin irritations). Once positive results are registered, you can start to pause the daily treatment.
Since the causes of hyperhidrosis differ between patients, you will have to adjust the therapy to
your individual needs and lifestyle. These factors may vary according to yearly seasons and every-
day occurrences.
Before you commence the session, take off all metal accessories (e.g. jewellery). Clean the skin in
the treatment areas. Remove all ointments, lotions and cosmetics.
Exception: All damages to the skin (minor injuries, scratches etc.) must be coated with vaseline
or a fatty lotion before the treatment to avoid further injuries. Damaged skin parts have an
especially high current permeability and offer a greater risk of injury. The “entirety” of the current
will run “only” through the damaged skin. Please only cover the spots affected by injury – caution
is advised, since vaseline and other fatty lotions block the current flow and impede the therapeutic
effect.
The device monitors the skin resistance and the electric conductivity of the water in order to
reduce the strain (anti-overtreatment protection).
If your tap water is very hard, an addition of cooking salt may help increase the conductivity.

12
EN SweatStop® DE20
Preparation
Connect the red and the black cables with the electrodes.
Now, plug the cables into the corresponding outlet socket located on the device: plug the red
cable into the red socket and the black cable into the black socket.
Change the polarity each time you start the therapy, unless otherwise recommended by your
doctor. The pole reversal can be carried out by plugging the red cable into the black socket and
the black cable into the red socket.
Treatment of the hands and / or feet
Place the tubs on a firm, level surface. For the treatment of the hands, place both trays side by side
on a table; for the treatment of the feet, place both trays side by side on the floor. If you treat
hands and feet simultaneously*, position one tray on the table and one on the floor.
* Since the conductivity of hands and feet varies, this is only recommended for experienced users.
The electrodes must never directly touch the skin. Otherwise you will risk burns! Please pour
a small amount of tap water (hand treatment: ~ 0.5 l, foot treatment: ~ 0.75 l) into each tub.
The water temperature should be according to your personal comfort and has no effect on the
therapy. The water should cover only the body parts affected by the hyperhidrosis – not the whole
hand or the whole foot.

Treatment of the underarms or other body parts
Place a tub on a firm, level surface and fill it with tap water (~ 1 l). Put the connected sponge
electrodes into the tub and soak them completely.
Hand treatment
Please read the chapter “Basics” first before you go on!
When conducting the hand treatment for the first time, ask another person to assist you with the
adjustment of the amperage.
When conducting the second treatment, simply start the device by turning the button and adjust
the amperage according to the value you used during your first treatment. Place both of your
hands into the water-filled tubs – one tub per hand. The current flow will be activated as soon
as the electric circuit is closed. The current strength will increase until the desired value has been
reached. You can take your hands out of the tub at any time to readjust the amperage. Please
note that you should only increase the amperage slowly. The increase of the current strength is
restricted, which means that turning the button quickly won‘t lead to an equally quick increase!
Choose the current type according to your prescription or doctor’s recommendation – direct
current is more effective, but most patients prefer the comfortable treatment feeling of the
pulsed current.
The current type, PC or DC, can only be selected when the device is turned off. Otherwise the
original choice will be kept.
To turn on the device, turn the switch (1) to the left. A text will appear on the display for 5 seconds;
this indicates that the device is running.
Now, check whether you have selected the correct current type. The first line on the display shows
if the device is set to „DC“ direct current or „PC“ pulsed current. Put your hands into the treatment
tubs – the water should cover only the areas affected by the hyperhidrosis – not the entire hand.
If necessary, adjust the water level.

14
EN SweatStop® DE20
When turning the button (1) clockwise, the amperage will be increased. The second line on the
display (5) shows the current flow.
Direct current:
Turn up the amperage until the current is
noticeable, then turn it down again until
you can no longer feel it.
Pulsed current:
Turn up the amperage until the current is
barely noticeable.

Iontophoresis treatment of the underarms using the DE 20
Treatment interval
The iontophoresis treatment should
initially be carried out once a day,
until the perspiration has decreased.
Afterwards, the application interval
can be adjusted to one treatment
every 1-3 days, or alternatively to
whatever setting is best for your
body.
The perspiration is usually reduced
after only a few treatments. In ex-
ceptional cases, it is possible that the
effect occurs only after a few weeks
or even months. For this reason, a
continuous treatment is recommen-
ded even when there is no initial
effect.
The therapy must be continued even
if the desired result has already been
achieved.
Rough guideline:
Alternate treatment and pause – every second day; three times a week with a minimum pause of
one day.
Paused treatment – every third day; two times a week with a minimum pause of two days.
The duration is fixed to 20 minutes to allow an evaluation of the effectiveness of the treatment;
this leads to a reduction of application errors. This time value has been deducted by scientifically
significant clinical studies (15 or 30 minutes).
Should you perceive the current as biting or unevenly intense, please reduce the current strength.
If you are conducting a treatment outside of the tubs, please soak the electrodes in the sponge
pockets anew or adjust their position on your body to make sure they are in full skin contact.
High currents do not lead to a more successful treatment, but can lead to skin irritations and
injuries instead. This is viewed as an application error. Direct current (DC) treatments should be
conducted subliminally (not noticeable). Pulsed current (PC) treatments should be conducted
slightly noticeably.

You should be able to feel the current, but it must NOT be uncomfortable. You will perceive every
treatment differently. This is why your last current settings should only be viewed as a benchmark.
You should adjust the current strength according to your comfort.
In cases of skin irritation, stop the treatment and seek advice from your doctor. Your doctor will
then decide whether the treatment can be continued.
Summary:
• Adjust the device to the direct current setting (DC). Use pulsed current (PC) for more sensitive
body parts. Due to its pauses, the pulsed current offers a finer dosage.
• Readjust the current strength before every new treatment.
• Duration of the treatment: 20 minutes.
• Sessions: once a day. Later, every 1-3 days or according to your personal needs.
• Remove all metal objects (jewellery).
• Change polarity before every treatment.
• Consult a doctor in cases of skin irritation.
Power supply
The device comes with a built-in battery compartment (8) for four standard rechargeable NiMH
batteries (= accumulators) connected in series, type HR14 (= Baby = C). In delivery condition,
their capacity is 2500 mAh. Due to this, the device can be operated independently from a power
connection.
Monitored battery / accumulator capacity
As soon as the battery voltage drops below a defined value, the yellow LED (4) will light up.
The display will alternatively show the message “battery low”, the current type, and the current
strength. You will be able to conduct a minimum of 2 more treatment sessions before the accumu-
lators need to be recharged. When the battery voltage drops further, the red LED (6) will light up.
The display will show the message “batteries empty”. You will have to recharge the accumulators
before you will be able to continue your treatment.
Charging the accumulators
The charging socket is located on the right side of the device (7). You may only use the supplied
charger, since it is adjusted to the accumulators built into the device. Connecting the device to the
wrong charger or power supply may lead to severe damage.
If the DC plug of the charger is inserted, the circuit will be interrupted and the device will be
deactivated.
Caution: Never try to recharge primary battery cells with the recharging unit – only rechargeable
NiMH batteries (“accumulators”) are allowed.
When replacing batteries, all four batteries must be replaced. The charging duration of the re-
chargeable batteries is 11 to 12 hours (delivery condition).
