1. GETTING TO KNOW YOUR DE-
VICE
Pain relief with the EM 29 stimulation device
How does electrical muscle stimulation work?
The knee and elbow TENS works on the basis of electrical
nerve stimulation (TENS). TENS, or transcutaneous electrical
nerve stimulation, relates to the electrical stimulation of the
nerves through the skin. TENS is an eective non-pharmaco-
logical method of treating dierent types of pain that have a
variety of causes. It has no side-eects if administered correc-
tly. The method has been clinically tested and approved and
can be used for simple self-treatment. The pain-relieving or
pain-suppressing eect is achieved by inhibiting the transfe-
rence of pain to nerve fibres (caused mainly by high-frequency
impulses) and by increasing the secretion of endorphins in the
body. Their eect on the central nervous system reduces the
sensation of pain. This method is clinically tested and appro-
ved. 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.

The knee and elbow TENS is intended for individual treatment
of pain in the knee and elbow.
Switching on
Hold down the On/O button [1] until a short signal sounds
and the LCD display [6] switches on. When the device is swit-
ched on for the first time, program A is automatically activated.
Selecting a program
Press the program button P [3] to switch between the pro-
grams.
The following programs are available:
Program Frequency Time
A 4 Hz – 110 Hz (3 phases) 30 min
B 4 Hz 25 min
C 2 Hz (burst) 25 min
D 100 Hz 25 min
Note:
With program A, you will feel the eect become stronger
when the program changes from phase 1 to phase 2 (af-
ter approx. 10 minutes). This is normal and intentional. If
the intensity seems too high, you can lower it by simply
pressing the intensity button ▼[2].
Note:
If the program is changed during stimulation (for ex-
ample from A to B), the output intensity will increase
gradually in the new program until it reaches the intensi-
ty that was previously set. This can be stopped if requi-
red by pressing and holding the intensity button ▼[2]
for two seconds or by switching o the device by pres-
sing and holding the On/O button [1] for two seconds.
Stopping pulses that are too strong
You can lower the intensity at any time or turn the device o
by pressing and holding the On/O button [1] (~ 2seconds).
Setting the intensity
Press the intensity button ▲[2] to gradually increase the inten-
sity or the intensity button ▼[2] to lower the intensity. There are
20 levels of intensity that can be selected. Depending on the
intensity level, you will start to feel tingling, which may increase
up to muscle contractions.
Select a setting that is comfortable for you during use.
Preventing unwanted pulse changes
To prevent unintentional increases in intensity during a treat-
ment, simply switch the button lock on. To do this, press and
hold the program selection button P [3] for approx. 2 seconds.
An acoustic signal sounds and the symbol “ ” appears in
the display [6]. To release the button lock, press and hold the P
button [3] for approx. 2 seconds.

10 11
Reacting to unpleasant sensations
If you feel a twinge or itching on your skin, you should switch
the device o and proceed as follows:
• Check that the electrodes are OK and do not show any
signs of damage.
• Check that the round cover is still on the electrode
connections.
• Remove the cu and moisten it again completely.
• When you put it back on, ensure that there is good contact
with the skin and that the skin is damp.
Pausing a program
If you want to pause a program while it is running, press the
Pause button [1]. An acoustic signal sounds and the pause
symbol “II” flashes in the display [6]. The program can be con-
tinued by pressing the button [1] again.
Contact detection
If the electrodes are not in contact with the body, the inten-
sity will automatically be set to zero. This prevents unwanted
electrical stimulation. The intensity cannot be increased if the
electrodes are not in contact with the body.
Memory function
The device saves the last program that was set.
After replacing the battery, the device starts again with the first
program.
