Getting to know your device

What is a digital EMS/TENS unit and what can it do?
Digital EMS/TENS units fall into the electrostimulation device category. They provide three basic functions suitable for combined operation:

1. Electrical stimulation of nerve tracts (TENS)
2. Electrical stimulation of muscle tissue (EMS)
3. A massage effect triggered by electrical signals

The unit also features two independent stimulation channels and four self- adhesive electrodes. It offers a wide range of functions for increasing general well-being, pain relief, maintaining physical fitness, relaxation, muscle revitalization, and combating tiredness.
For these purposes, you can either choose from pre-set programs or specify your own to suit your individual needs.
The principle of electrostimulation devices is based on the imitation of impulses in our bodies that are transferred to nerve and muscle fibers using electrodes via our skin. The electrodes can be applied to many parts of the body; the electrical impulses are completely harmless and virtually painless. In certain applications, you will merely notice a slight tingling or vibrating sensation. The electrical impulses that are sent into the tissue influence the transmission of stimulation into nerves, nerve centers, and muscle groups in the
application area.
Electrostimulation usually only has an effect after regular applications. With regard to muscles, electrostimulation does not replace regular training. However, it is a sensible, supplementary training element.
TENS, or transcutaneous electrical nerve stimulation, relates to the electrical stimulation of the nerves via the skin. TENS is an effective non- pharmacological method of treating different types of pain that have a variety of causes. It has no side effects if administered correctly. The method has been clinically tested and approved and can be used for simple self-treatment. The pain-relieving or pain-suppressing effect is achieved by inhibiting the transference of pain to nerve fibers (caused mainly by high-frequency impulses) and by increasing the secretion of endorphins in the body. Their effect on the central nervous system reduces the sensation of pain. The method is scientifically substantiated and approved as a form of medical treatment.
Any symptoms that could be relieved using TENS must be checked by your GP. Your doctor will also give you instructions on how to carry out a TENS self- treatment regime.
TENS is clinically tested and approved to treat the following complaints:

• Back pain, particularly in the lumbar/cervical spine area
• Sore joints (e.g. knee, hip, and shoulder joints)
• Neuralgia
• Menstrual cramps in women
• Pain resulting from injury to the musculoskeletal system
• Pain caused by circulatory disorders
• Chronic pain with various causes.

Electrical muscle stimulation (EMS) is a widespread and generally recognized method and has been used in sports medicine and rehabilitation for years. In sports and fitness, EMS is used to complement conventional muscle training, increase the performance of muscle groups, and adjust physical proportions to achieve the desired aesthetic results. There are two different types of EMS application: one is for targeted strengthening of the muscles (activating application), and the other is to achieve a relaxing, restful effect (relaxing application).
The activating application involves:

• Muscle training to increase endurance and/or
• Muscle training to support the strengthening of specific muscles or muscle groups, and to achieve the desired changes to physical proportions

The relaxing application involves:

• Muscle relaxation for easing muscle tension
• Improving symptoms of muscular fatigue
• Acceleration of muscle regeneration after high muscle performance (e.g. after a marathon)

Thanks to integrated massage technology , digital EMS/TENS units are also able to relieve muscle tension and combat fatigue with a program based on the sensation and effects of a real massage.
The positioning suggestions and program tables in these instructions for use allow you to quickly and simply determine the corresponding application (depending on the affected area of the body) and set the unit to achieve the desired effects.
Thanks to the two separately adjustable channels, the digital EMS/ TENS unit offers you the advantage of being able to set the intensity of the impulses independently from each other for two treatment areas on the body, for example, to cover both sides of your body or to evenly stimulate larger areas of tissue. The option to individually set the intensity of each channel also enables you to treat two separate areas of the body simultaneously instead of having to treat the individual areas in turn, which saves you time.

Important notes

The device is not a substitute for medical consultation and treatment. Consult your doctor first if you are experiencing any pain or are suffering from an illness.
WARNING!
To avoid damage to health, we strongly advise against using the digital EMS/TENS unit in the following situations:

• **** With implanted electrical devices (such as a pacemaker)
• In the case of metal implants
• If you use an insulin pump
• If you have a high temperature (e.g. > 39°C)
• If you have a known or acute cardiac arrhythmia, or disorders of the heart’s impulse and conduction system
• If you suffer from a seizure disorder (e.g. epilepsy)
• If you are pregnant
• If you have cancer
• After an operation, strong muscle contractions could affect the healing process
• The device must never be used near to the heart. The stimulation electrodes must not be placed on any part of the front ribcage (where the ribs and breastbone are located), especially not on the two large pectorals. this can increase the risk of ventricular fibrillation and induce cardiac arrest.
• On the skeletal skull structure, or around the mouth, throat, or larynx
• In the neck/carotid artery area
• In the genital area
• On acutely or chronically diseased (injured or irritated) skin (e.g. inflamed skin – whether painful or not, reddened skin, rashes, e.g. allergies, burns, bruises, swellings, both open and healing wounds, and post-operative scars where the healing process could be affected)
• In humid environments (e.g. in the bathroom) or when bathing or showering
• Do not use after consuming alcohol
• If connected to a high-frequency surgical device
• In the case of acute or chronic diseases of the gastrointestinal tract
• The stimulation should not be applied above or through the head, directly onto the eyes, covering the mouth, to the front of the neck (especially not to the carotid artery), or with the electrode surfaces placed on the chest and upper back or across the hear

Before using the device, consult your doctor if any of the following applies to you:

• Serious illnesses, in particular, if you suspect or have been diagnosed with high blood pressure, a blood coagulation disorder, propensity to thrombo-embolic conditions, or recurrent malignant growths
• Any skin conditions
• Unexplained chronic pain in any part of the body
• Diabetes
• Any sensory impairment that reduces the feeling of pain (e.g. metabolic disorders)
• If you are receiving medical treatment
• In the event of complaints linked to stimulation treatment
• If you suffer from persistently irritated skin due to long-term stimulation at the same electrode site

IMPORTANT!
Only use digital EMS/TENS units:

• On adults
• For the intended purpose and as specified in these instructions for use. Improper use can be dangerous.
• For external use
• With the original accessories supplied, which can be re-ordered. Failure to do so invalidates the warranty.

PRECAUTIONS:

• Always pull firmly on electrodes to remove them from the skin to prevent injuries in the unusual case of highly sensitive skin.
• Keep the device away from sources of heat and do not use it in close proximity (approx. 1 m) to shortwave or microwave devices (e.g. mobile phones), as doing so can result in unpleasant current peaks.
• Do not expose the device to direct sunlight or high temperatures.
• Protect the device from dust, dirt, and humidity.
• Never immerse the device in water or other liquids.
• The device is suitable for self-treatment.
• For hygiene reasons, the electrodes may only be used on one person.
• If the device does not work properly, or you feel unwell or experience pain, stop using it immediately.
• Switch off the unit or the respective channel first before removing or relocating electrodes to prevent unintentional stimulation.
• Do not modify electrodes (e.g. by cutting them). This increases the current intensity, which is potentially hazardous (max. recommended output value for the electrodes is 9 mA/cm², an effective current intensity beyond 2 mA/cm² requires increased awareness).
• Do not use the device whilst asleep, driving a vehicle, or operating machinery.
• Do not use it whilst undertaking any activity where an unexpected reaction (e.g. strong muscle contractions even at low intensity) could be dangerous.
• Ensure that no metallic objects (e.g. belt buckles or necklaces) come into contact with the electrodes during stimulation. If you are wearing jewelry or have piercings in the area to be treated (e.g. a navel piercing), these must be removed before using the device. Failure to do so could result in spot burns.
• Keep the device away from children.
• Make sure not to confuse the electrode cables including contacts with your headphones or other devices and do not connect the electrodes to other devices.
• Do not use the device whilst using other devices that transmit electrical impulses into your body.
• Do not use in the vicinity of highly flammable substances, gases, or explosives.
• Do not use rechargeable batteries and always use the same battery types.
• During the initial few minutes, use the device while sitting or lying down to minimize the risk of injuries as a consequence of isolated cases of vagal responses (feeling of faintness). If you feel faint, immediately switch off the device, lie down and support the legs in an elevated position (approx. 5 – 10 min).
• Treatment of the skin with moisturizing lotions or ointments beforehand is not recommended as this considerably increases the electrode wear and may cause unpleasant current peaks.
• This device is not intended for use by children or people with restricted physical, sensory (e.g. reduced sensitivity to pain) or mental skills or a lack of experience and/or lack of knowledge unless they are supervised by a person who is responsible for their safety or is instructed by such a person in how to use the device.
• If the adhesive capability of the adhesive electrodes decreases, please replace them immediately. Only use the device again with new adhesive electrodes. Otherwise, the unequal adhesion of the adhesive electrodes may lead to skin injuries. Replace the electrodes with new ones after having used them 20 times at the latest.

Information regarding the positioning of electrodes

It is fundamental to the intended success of electrostimulation applications that electrodes are positioned sensibly.
We recommend that you consult your doctor to establish the ideal electrode positions for your intended application area.
The figure on the display is intended as an initial aid to help you position the electrodes.
The following applies to the selection of electrode positions:
Electrode distance
The larger the distance between electrodes, the larger the stimulated tissue volume. This applies to the area and depth of the tissue volume. At the same time, however, the stimulation intensity of the tissue falls the further the electrodes are apart. As a result, greater distances between electrodes mean a larger tissue volume is stimulated, but less intensively. Consequently, you must increase the impulse intensity to boost stimulation.
The following guideline applies to the selection of the electrode distance:

• Sensible distance: approx. 5 – 15 cm
• At distances below 5 cm, the unit primarily stimulates surface structures intensively
• At distances in excess of 15 cm, large areas and deep structures are stimulated very weakly Relationship between electrodes and muscle fiber structures

Relationship between electrodes and muscle fiber structures
Adapt the current flow direction to the fiber structure of the muscle according to the muscle layer you would like to treat. If you are targeting superficial muscles, position the electrodes in parallel to the fiber structure (A – B / C – D) and if you are targeting deeper layers of tissue, position the electrodes across the fiber structure. You can do this by positioning electrodes as crosses (i.e. diagonally), such as A – D / B-C.
As part of pain relief treatment (TENS) using the digital EMS/ TENS unit and its 2 separately adjustable channels and 2 adhesive electrodes each, it is advisable either to position the electrodes of a channel so that the area affected by the pain is between the electrodes or to position one electrode directly on the area affected by the pain and the other electrode at a minimum distance of 2 – 3 cm.
You may use the electrodes of the second channel to simultaneously treat additional areas affected by pain or use them in conjunction with the electrodes of the first channel to restrict the area affected by pain (position electrodes opposite). In this case, we once again recommend positioning electrodes as crosses.
Tip for the massage function: always use all four electrodes for optimum treatment.
Use the electrodes on skin that is clean and preferably free from hair and grease in order to prolong the life of the electrodes.
If required, clean the skin with water and remove hair prior to treatment. If an electrode should come loose during use, the impulse intensity of both channels is reduced to the lowest level. Apply the electrode again and reset the desired impulse intensity.

Current parameters

Electrostimulation units operate with the following current settings, which may affect stimulation effects differently, depending on the setting:

Impulse shape

This describes the time function of the electrical impulse.
It distinguishes between monophasic and biphasic pulse currents. In monophasic pulse currents, the current flows in one direction, and in biphasic pulse currents, the electrical impulse alternates its direction.
The digital EMS/TENS unit only provides biphasic pulse currents as these relieve muscles, cause little muscle fatigue and provide a safer application.

Impulse frequency

The frequency indicates the number of individual impulses each second and is given in Hz (Hertz). It can be calculated by determining the cyclic value for the time period. The relevant frequency determines which types of muscle fibers react favorably. Slow-reacting fibers react more easily to lower impulse frequencies up to 15 Hz, whereas fast-reacting fibers only respond from approximately 35 Hz onwards. Impulses of approx. 45 – 70 Hz are linked with constant tension in the muscles and quicker fatigue. Higher impulse frequencies are therefore favorable in strength and maximum power training.

Impulse width

This indicates the duration of an individual impulse in microseconds. The impulse width, therefore, determines, among other things, the penetration of the electricity, where usually: larger muscle masses require larger impulse widths.

Impulse intensity

Setting the intensity levels depends on the individual sensitivity of each user and is determined by a variety of variables, such as the site of application, blood circulation to the skin, skin thickness, and the quality of the electrode contact. The setting used should be effective but should never cause an unpleasant sensation, such as pain, at the site of application. While a gentle tingling indicates sufficient stimulation energy levels, any setting that causes pain should be avoided.
During longer applications, it may be necessary to make readjustments due to the adjustment processes over time at the site of the application.

Cycled impulse parameter variation

In many cases, it is necessary to cover the overall tissue structure at the site of application by applying several impulse parameters. In the digital EMS/TENS unit, this is achieved by the provided programs, which automatically make a cyclical impulse parameter change. This also prevents individual muscle groups at the site of the application from being affected by fatigue. The digital EMS/TENS unit provides sensible default current parameter settings. With this, you can change the impulse intensity at any time during use. For 6 programs you can also set various parameters for stimulation yourself.

Cleaning and storage

Adhesive electrodes

• To ensure that the adhesive electrodes remain adhesive for as long as possible, clean them carefully with a damp, lint-free cloth or clean the underside of the electrodes under lukewarm, running water and pat dry with a lint-free cloth.
  Before cleaning with water, remove the connection cables from the electrodes.

• Reapply the electrodes to the carrier foil following treatment.

Cleaning the device

• Remove the batteries from the device before cleaning.
• Clean the device after use with a soft, slightly damp cloth. If it is very dirty, you can also moisten the cloth with a mild soapy solution.
• Do not use any chemical or abrasive cleaning agents.
  Ensure that no water enters the device.

Reuse of the device
Once it has been properly prepared, the device can be used again. Preparation includes replacement of the treatment electrodes as well as cleaning of the surface of the device using a cloth moistened with a mild soapy solution.
Storage

• Remove the batteries from the device if you will not be using it for a prolonged period of time. Leaking batteries may damage the device.
• Do not make sharp bends in the connection cables and electrodes.
• Disconnect the connection cables from the electrodes.
• Reapply the electrodes to the carrier foil after use.
• Store the device and accessories in a cool, well-ventilated space.
• Never place any heavy objects on the device.

The empty, completely flat batteries should be disposed of through specially designated collection boxes, recycling points, or electronics retailers. You are legally required to dispose of the batteries.
Note: The codes below are printed on batteries containing harmful substances:
Pb = Battery contains lead, Cd = Battery contains cadmium, Hg = Battery contains mercury.
For environmental reasons, do not dispose of the device in the household waste at the end of its useful life. Dispose of the unit at a suitable local collection or recycling point. Dispose of the device in accordance with EC Directive – WEEE (Waste Electrical and Electronic Equipment). If you have any questions, please contact the local authorities responsible for waste disposal.

Problems/solutions

The device does not switch when the ON/OFF button is pressed. How to proceed :

1. Ensure batteries have been inserted correctly and are in contact with the terminals.
2. Replace batteries, if applicable.
3. Contact Customer Services.

Electrodes do not adhere to the body. How to proceed:

1. Clean the adhesive surface of the electrodes using a damp, lint-free cloth. Replace the electrodes if they still do not adhere securely.
2. Clean the skin prior to any application; do not use skin care lotions or oils prior to treatment. Shaving may increase the life of electrodes.

There is no noticeable stimulation. How to proceed:

1. Press the ON/OFF button to interrupt the program. Check the connection cables are correctly connected to the electrodes. Ensure the electrodes are in firm contact with the treatment area.
2. Ensure the connection plug is firmly connected to the device.
3. Press the ON/OFF button to restart the program.
4. Check electrode positions and ensure that adhesive electrodes do not overlap.
5. Gradually increase the impulse intensity.
6. The batteries are almost empty. Replace the batteries.

The battery symbol is shown. How to proceed:
Replace all batteries.
You have an unpleasant sensation at the electrodes. How to proceed:

1. The electrodes are not positioned correctly. Check their positions and re-position, if necessary.
2. The electrodes are worn. This may cause irritated skin as even distribution of the current across the entire area is no longer guaranteed. For this reason, replace the electrodes.

Skin in the treatment area turns red. How to proceed:
Immediately stop treatment and wait until your skin has returned to its normal condition. If the redness is under the electrode and disappears quickly, there is no risk – this is caused by the locally stimulated, increased blood flow.
However, consult your doctor before you continue treatment if the skin irritation persists and this is accompanied by an itchy sensation or inflammation. This may be caused by an allergic reaction to the adhesive surface.
