It is fundamental to the intended success of electrostimulation applica-
tions that electrodes are positioned sensibly.
We recommend that you consult your doctor to establish the ideal elec-
trode positions for your intended application area.
The figure on the display is intended as an initial aid to help you posi-
tion the electrodes.
The following applies to the selection of electrode positions:
Electrode distance
The larger the distance between electrodes, the larger the stimulated tis-
sue 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 stimula-
tion.
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 struc-
tures 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 struc-
ture (A – B / C – D) and if you are targeting deeper lay-
ers 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 elec-
trodes each, it is advisable either to position the electrodes of a
channel so that the area affected by the pain is between the elec-
trodes 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 simultane-
ously treat additional areas affected by pain or use them in con-
junction 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 treat-
ment.
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.

A (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.
