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 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 fibre structures 

Adapt the current flow direction to the fibre 

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 fibre structure (A – B / C – D) and if 

you are targeting deeper layers of tissue, position 

the electrodes across the fibre 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.

7.  Customisable programs

(Applies for TENS 13-15, EMS 33-35)

The programs TENS 13-15 and EMS 33-35 can be customised 

according to your needs. 

TENS 13 program

TENS 13 is a program that you can also customise. In this program, 

you can set the impulse frequency to between 1 and 150 Hz and the 

impulse width to between 80 and 250 µs.
1.  Place the electrodes on the desired area for treatment (for 

positioning suggestions see section “6.4 Information regarding 

the positioning of electrodes”) and connect them to the device.

2.  Select the TENS 13 program as described in section “5.2 Starting 

application” (step 3 to step 5).
