Getting to know your device

What is Digital TENS/EMS and what can it do

Digital TENS/EMS belongs to the group of electrical stimulation systems. It has three basic functions, which can be used in combination:

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

For this, the device has four independent stimulation channels and eight selfadhesive electrodes. It has various versatile functions in order to increase general wellbeing, alleviate pain, maintain physical fitness, relaxation, revitalise muscles and combat fatigue. You can either select these functions from preset programmes or determine them yourself according to your requirements. The operating principle of electrical stimulation equipment is based on simulating the body's own pulses which are transmitted transcutaneously to nerve or muscle fibres by means of electrodes. The electrodes can thereby be attached to many parts of the body, whereby the electrical stimuli are safe and practically painless. You merely feel a gentle prickling or vibrating in some applications. The electrical pulses transmitted to the tissue affect the transmission of stimulation in nerve conductions as well as neural nodes and muscle groups in the field of application.
The effect of electrical stimulation is generally only recognisable after regularly repeated application. Electrical stimulation does not replace regular exercising of the muscle, but is able to reasonably supplement the effect thereof.
TENS, transcutaneous electrical nerve stimulation, means electrical stimulation of nerves through the skin. TENS is recognised as a clinically proven, effective, non-medication method of treating pain from certain causes. It is free from side-effects when used properly, and can also thereby be used as a simple meeans of self-treatment. The pain-alleviating or suppressing effect is also achieved by preventing pain from being passed on into nerve fibres (above all through high-frequency pulses) and increasing the secretion of the body's own endorphines which reduce awareness of pain through their effect on the central nervous system. The method is scientifically underpinned and medically approved.
Any symptoms indicating TENS application must be clarified with the doctor in charge of your treatment. The latter will also give you information on the respective benefits of TENS self-treatment.
TENS is clinically tested and approved with the following applications:

• Back pain, particularly also lumbar and cervical spine problems.
• Joint pain (e.g. knee joint, hip joint, shoulder).
• Neuralgia.
• Headaches.
• Women's period pains.
• Pain after injuries to musculoskeletal system.
• Pain with circulatory problems.
• Chronic pain through various causes.

Electrical muscle stimulation (EMS) is a widespread and generally recognised method and has been used for years in sports and rehabilitation medicine. In the sports and fitness field, one of the uses of EMS is as a supplement to conventional muscle training, in order to increase the efficiency of muscle groups and adapt physical proportions to the desired aesthetic results. EMS application goes in two directions. On the one hand, a targeted strengthening of musculature can be produced (activating application) and on the other hand a relaxing, resting effect can also be achieved (relaxing application).

Active application includes the following:

• Muscle training to improve endurance performance and/or
• Muscle training to support the strengthening of certain muscles or muscle groups in order to achieve desired changes to body proportions.

Relaxing application includes the following:

• Muscle relaxation in order to loosen up muscular tension.
• Improving muscular fatigue symptoms.
• Accelerating muscle regeneration after high muscular performance (e.g. after a marathon).

Through integrated massage technology, Digital TENS/EMS also offers the possibility of reducing muscular tension and combating fatigue symptoms using a programme based on real massage in terms of sensation and effect.
Using the positioning suggestions and programme charts in this manual, you can determine the device setting fast and easily for the respective application (depending on the region of the body affected) in order to ensure the desired effect.
Through the four separately adjustable channels, the Digital TENS/EMS has the advantage of adapting pulse intensity independently to several parts of the body to be treated, for example in order to cover both sides of the body or ensure even stimulation of larger areas of tissue. The individual intensity setting of each channel also allows you to treat up to four different parts of the body at the same time, making for a time saving compared with individual sequential treatment.

Current parameters

Electrical stimulation devices operate with the following current settings, which will alter the stimulation effect depending on the setting.

Pulse shape

This describes the time function of the excitation current, whereby monophase pulse trains are differentiated from biphase. With monophase pulse trains, the current flows in one direction. With biphase pulses, the excitation current alternates its direction.
In the Digital TENS/EMS unit, there are only biphase pulse trains, as they reduce the strain on the muscle, leading to less muscle fatigue as well as safer application.

Pulse frequency

Frequency indicates the number of individual pulses per second, and is indicated in Hz (Hertz). It can be calculated by working out the inverse value of the periodic time. The respective frequency determines which types of muscle fibre preferably react.

Slow-response fibres tend to react to lower pulse frequencies up to 15 Hz, while fast-response fibres only respond to frequencies over approx. 35 Hz. With pulses of approx. 45-70 Hz, there is permanent tension in the muscle combined with premature muscle fatigue. Higher pulse frequencies can therefore preferably be used for elasticity and maximum strength training.

Pulse width

Pulse width is used to indicate the duration of an individual pulse in microseconds. Pulse width also determines the penetration depth of the current whereby in general, the following applies: a greater muscle mass requires a greater pulse width.

Pulse intensity

Setting the degree of intensity is individually dependent on the subjective feeling of each individual user and is determined by a number of parameters such as application site, skin circulation, skin thickness as well as quality of electrode contact. The actual setting should be effective but should never produce any unpleasant sensations such as pain at the site of application. While a slight tingling sensation indicates sufficient stimulation energy, any setting which leads to pain must be avoided.
With prolonged application, readjustment may be necessary due to time adjustment processes at the site of application.

ON and OFF time

ON time describes the stimulation time of the cycle in seconds, i.e. the length of the cycle in which pulses are delivered to the body. OFF time, on the other hand, indicates the length of the cycle (in seconds) which is stimulation-free.

Cycle-controlled pulse parameter variation

In many cases it is necessary to cover the entirety of tissue structures at the site of application by using several pulse parameters. With the Digital TENS/ EMS unit, this is done by the existing programmes automatically making a cyclical pulse parameter change. This also prevents individual muscle groups at the site of application from getting tired.
With the Digital TENS/EMS unit there are useful presettings for current para meters. During the application, however, you do have the possibility of changing pulse intensity at any time and, with individual programmes, you can also alter pulse frequency beforehand in order implement the application which is the most comfortable or promises the most success for you.

Programme overview

Basic information

The Digital TENS/EMS unit has a total 50 programmes:

• 20 TENS programmes
• 20 EMS programmes
• 10 MASSAGE programmes

With all programmes, you can set the length of application and (for each of the four channels) pulse intensity separately.
Besides this, with TENS and EMS programmes 11-20, in order to physically adapt the stimulation effect to the structure of the site of application, you can also change both the pulse frequency, pulse width, ON and OFF times of the individual cycles as well as the number of cycles.
Cycles are the different sequences making up the programmes. They automatically run one after the other and increase the efficacy of stimulation on different types of muscle fibre and combat premature muscle fatigue.
You will find the standard stimulation parameter settings and information on placing the electrodes in the following programme charts for TENS, EMS and MASSAGE.

TENS programmes

On Time (sec.) = Cycle switch-on time in seconds (contraction) – Off Time (sec.) = Cycle switch-off time in seconds (relaxation)
Note: Electrode position is supposed to surround the painful area. With painful muscle groups, the electrodes are grouped round the muscle affected. In case of joint pain, the joint on the front/rear side of the joint and, if electrode distances permit, on the right and left sides of the joint, should be surrounded with electrodes. Minimal electrode distance should not be less than 5 cm and not exceed 15 cm. See figure no. 9 and 10 for knee and ankle joint.
Burst programmes are suitable for all sites which should be treated with an alternating signal pattern (to ensure minimum habituation).

EMS-Programme

On Time (sec.) = Cycle switch-on time in seconds (contraction) – Off Time (sec.) = Cycle switch-off time in seconds (relaxation)

MASSAGE programmes

Electrodes must be placed so that they surround the muscle segments in question. For optimal effect, electrode distance must not be greater than approx. 15 cm.
The electrodes should not be applied to the anterior wall of the thorax, i.e. never massage the left or right large pectoral muscle.

Information on placing the electrodes

For the desired success of any stimulation application, it is important that electrodes are placed sensibly.
We advise you to coordinate with your doctor regarding the best electrode positions for your intended field of application.
The electrode positions suggested inside the cover (Figs. 1-28) serve as a guide. The following applies when choosing electrode positions:

Electrode distance
The greater the electrode distance which is selected, the greater will be the volume of tissue that is stimulated. This applies to the area and the depth of the tissue volume. At the same time, however, the strength of tissue stimulation decreases as the electrode distance becomes greater, which means that, if a greater electrode distance is chosen, a greater volume is stimulated, but stimulation is weaker. To increase stimulation, pulse intensity must then be increased.
The following guideline holds when selecting electrode distances:

• most reasonable distance: approx. 5-15 cm.
• below 5 cm, it is mainly surface structures which are strongly stimulated.
• over 15 cm, large-area and deep structures are stimulated very weakly.

Electrode relationship to muscle fibre orientation

Choice of current flow direction must be adapted to the muscle fibre orientation according to the desired muscle layer. If surface muscles are to be reached, the electrodes must be placed parallel to the fibre orientation (fig. 16; 1A-1B/2A-2B). If deep tissue layers are to be reached, the electrodes must be placed crosswise to the fibre orientation (fig. 16; 1A-2A/1B-2B). The latter arrangement can, for example, be achieved via the cross electrode arrangement, e.g. fig. 16; 1A-2B/2A-1B. Note the colour-codes of the cables and the channels. The white cable belongs to channel CH1/3 and the grey cable to channel CH2/4.

In the treatment of pain (TENS) using the Digital TENS/EMS device with its 4 separately controllable channels and in each case 2 adhesive electrodes, it is advisable to either position the electrodes of one channel so that the pain spot lies between the electrodes or else you can position one electrode directly on the pain spot and the other at least 2-3 cm away.
The electrodes of the other channels can be used to treat other pain spots simultaneously or else, however, together with the electrodes of the first channel, to surround the pain area (opposite). A cross arrangement is again advisable here.
Massage function tip: use all electrodes to ensure optimal treatment.
In order to extend the service life of the electrodes, use them on clean skin which is as free as possible of hair and grease. If necessary, clean the skin with water before use and remove any hair.
If an electrode becomes detached during the application, the pulse intensity of this channel goes back to the lowest setting. Press the ON/OFF key to enter pause mode, reposition the electrode and continue application by pressing the ON/OFF key again and setting the required pulse intensity.

Cleaning and storage

Adhesive electrodes:

• In order to ensure that the electrodes adhere for as long as possible, they should be cleaned carefully with a damp, lint-free cloth.
• After use, stick the electrodes onto the backing film.

Cleaning the unit:

• Remove the batteries from the device every time you clean.
• Clean the unit after use with a soft, slightly moistened cloth. In case of more extreme soiling you can also moisten the cloth with mild soapy water.
• Ensure that no water penetrates into the device. If this should ever happen, only use the device again once it is completely dry.
• Do not use any chemical cleaners or abrasive agents for cleaning.

Storage:

• Remove the batteries from the unit if you are not going to use it for a longer period. Leaking batteries can damage the unit.
• Do not make any sharp kinks in the connecting leads or electrodes.
• Detach the connecting cable from the electrodes.
• After use, stick the electrodes onto the backing film.
• Store the device in a cool, well-ventilated place.
• Never place any heavy objects on the device.

Problems and solutions

The device does not switch on when the ON/OFF button is pressed. What should I do?

1. Make sure that the batteries have been inserted correctly and have contact.
2. Change the batteries if necessary.
3. Contact customer service.

The electrodes are detaching themselves from the body. What should I do?

1. Clean the adhesive surface of the electrodes with a damp, lint-free cloth. Then let them dry in the air and attach them again. Should the electrodes still not adhere firmly, they must be replaced.
2. Before each application, clean the skin, avoiding using any skin cream or oils before treatment. Shaving can increase adhesion of the electrodes.

The device is giving out abnormal signal tones during treatment. What should I do?

1. Look at the display. Is any channel flashing? > Interrupt the programme by pressing the ON/OFF button. Make sure that the connecting leads are properly connected to the electrodes. Make sure that there is a firm contact between the electrodes and the treatment area.
2. Make sure that the plug of the connecting lead is firmly connected to the device.
3. If the signal tones do not stop and the channel is flashing, change the connecting cable.
4. The display shows a flashing battery signal. Renew the batteries.

There is no noticeable stimulation. What should I do?

1. If a warning signal sounds, go through the steps described above.
2. Press the ON/OFF key to start the programme again.
3. Check that the electrodes are positioned properly and make sure that the adhesive electrodes are not overlapping.
4. Increase pulse intensity in stages.
5. The batteries are almost empty. Replace these.

You are aware that the electrodes feel uncomfortable. What should I do?

1. The electrodes are badly positioned. Check positioning and if necessary reposition the electrodes.
2. The electrodes are worn. Due to the fact that current distribution can no longer be guaranteed evenly over the entire surface, these may lead to skin irritation. You must therefore replace these.

The skin in the treatment area becomes red. What should I do?
Stop treatment immediately and wait until the skin has returned to normal. If any redness beneath the electrode soon disappears, this is not dangerous and is due to the increased circulation which has been stimulated locally.
If, however, the skin irritation remains and there is possibly itching or inflammation, please consult your doctor before further use. It may possibly be caused by an allergy to the adhesive surface.

Use of the device does not replace medical consultation and treatment. In the event of any type of pain or illness, you must therefore always first ask your doctor.

In order to prevent any damage to health, we would urgently advise against using the Digital TENS/EMS in the following cases:

• With any implanted electrical devices (such as pacemakers).
  
• If there are any metal implants.
• When using an insulin pump.
• In case of high fever (e.g. > 39°C).
• In case of known or acute cardiac arrhythmias and other disorders in stimulus formation and conduction of the heart.
• If suffering from attacks (e.g. epilepsy).
• If pregnant.
• In case of cancer.
• After operations where increased muscle contractions might impair the healing process.
• Never use near the heart. Stimulation electrodes should never be placed anywhere on the front of the thorax (marked by ribs and breastbone), but above all not on the two large pectoral muscles. Here it can increase the risk of ventricular fibrillation and lead to cardiac arrest.
  
• On the bony part of the cranium, near the mouth, throat or larynx.
• Near the throat / carotid artery.
• Near the genitals.
• On acutely or chronically diseased (injured or inflamed) skin (e.g. in the event of painful and painless inflammation, reddening, skin rashes (e.g. allergies), burns, bruises, swellings, open wounds and wounds in the process of healing, on operation scars in the process of healing).
• In environments with high humidity such as in the bathroom or when having a bath or shower.
• In the case of acute or chronic diseases of the gastrointestinal tract.
• Stimulation should not be carried out around or on the head, directly over the eyes, on the mouth, the throat (the cartoid artery in particular) or using electrodes placed on the chest, the upper back or over the heart.
• Do not use after consuming alcohol.
• When a high frequency surgical device is connected at the same time.

Before using the device, you should consult with the doctor in charge of your treatment in the event of the following:

• Acute diseases, especially if hypertension is suspected or actually exists, or blood-clotting disorders, tendency to thromboembolic diseases or in case of malignant new masses.
• All skin diseases.
• Chronic pain disorders which have not been clarified, regardless of the region of the body.
• Diabetes.
• All sensitivity disorders with reduced pain awareness (such as metabolic disturbances).
• Medical treatments carried out simultaneously.
• Complaints arising as a result of the stimulation treatment.
• Constant skin irritation as a result of prolonged stimulation at the same electrode point.

Use the Digital TENS/EMS solely:

• On humans.
• For the purpose for which it was developed and in the manner specified in these instructions for use. Any improper use can be hazardous.
• For external application.
• With the original accessory parts which are supplied and can be re ordered, otherwise the warranty becomes null and void.

PRECAUTIONARY MEASURES:

• Always remove the electrodes from the skin with a moderate pull in order to avoid injury in the event of highly sensitive skin.
• Keep the device away from heat sources and never use it near (~1 m) short-wave or microwave equipment (e.g. mobile phones), as this may lead to unpleasant current spikes.
• Do not expose the device to direct sunlight or high temperatures.
• Protect the device from dust, dirt and humidity. Never submerge the device in water or other liquids.
• The device is suitable for private use.
• For reasons of hygiene, the electrodes should only be used on one person.
• If the device is not functioning properly, or if you start feeling unwell or there is any pain, stop the application immediately.
• To remove or move the electrodes, first switch off the device or the appropriate channel in order to avoid unwanted irritation.
• Never modify any electrodes (e.g. by cutting). This leads to a higher current density and can be dangerous (max. recommended output value for electrodes: 9 mA/cm², an effective current density over 2 mA/cm² requires greater attention).
• Do not use when asleep, when driving a vehicle or at the same time as operating devicery.
• Never use with any activities where an unforeseen reaction (e.g. increased muscle contraction despite low intensity) may be dangerous.
• Make sure that no metallic objects such as belt buckles or necklaces can come in contact with the electrodes during stimulation. If you wear any jewellery or piercings (e.g. belly piercing) near the application site, you must remove these before using the device as burning may otherwise occur at some points.
• Keep the device away from children to prevent any hazards.
• Do not confuse the electrode cables and contacts with your headphones or other devices, and do not connect the electrodes to other devices.
• Do not use this device at the same time as other equipment which sends electrical pulses to your body.
• Do not use it near any highly flammable substances, gases or explosives.
• Never use accumulators, always use the same types of battery.
• In the initial minutes, carry out the application sitting or lying down in order to avoid any unnecessary risk of injury in the rare event of a vagal reaction (feeling of weakness). If you start feeling weak, switch the device off immediately and put your legs up (approx. 5-10 minutes).
• It is not advisable to apply any enriching creams or ointments to the skin beforehand, as this greatly increases electrode wear or else unpleasant current spikes may occur here.

Damage:

• If the device is damaged, do not use it if you are in any doubt but rather contact your dealer or the customer service address indicated.
• Check the device at regular intervals for signs of wear or damage. If you find any such signs or if the device was used improperly, you must bring it to the manufacturer or dealer before it is used again.
• Switch off the device immediately if it is defective or if is not working properly.
• Do not, under any circumstances, attempt to open or repair the device yourself! Only have repairs carried out by the customer service department or an authorized dealer. If these instructions are not heeded, the warranty becomes null and void.
• The manufacturer assumes no liability for damage caused through improper or wrong use.
