•

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 reac-

tion (feeling of weakness). If you start feeling weak, switch the machine 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 be-

forehand, as this greatly increases electrode wear or else unpleasant current

spikes may occur here.

Damage

•

If the device is damaged, do not use it and contact your retailer or the speci-

fied Customer Services address.

• 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 machine your-

self! 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.

3. Current parameters

Electrical stimulation machines operate with the following current settings,

which will alter the stimulation effect depending on the setting.

3.1 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 EMS/TENS 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.

3.2 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 com-

bined with premature muscle fatigue. Higher pulse frequencies can therefore

preferably be used for elasticity and maximum strength training.

3.3 Pulse width

Pulse width is used to indicate the duration of an individual

pulse in microseconds. Pulse width also determines the

pene tration depth of the current whereby in general, the fol-

lowing applies: a greater muscle mass requires a greater

pulse width.

3.4 Pulse intensity

Setting the degree of intensity is individually depend-

ent 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 pro-

duce 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 adjust-

ment processes at the site of application.

3.5 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 EMS/TENS

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 EMS/TENS unit there are useful presettings for current para-

meters. 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.

can I stick the electrodes high on my back? between the shoulder blades? or is this dangerous because it's too close to the heart? Submitted on 28-2-2020 at 09:10
