You can also set the working time and pause time for this program to
between 1 and 30 seconds each.
1. Place the electrodes on the desired area for treatment (for positio-
ning suggestions see electrode positions in section 8.4) and connect
them to the device.
2. Select the EMS 30 program as described in section “8.2 Starting
use” (step 3 to step 5).
3. Use the
UP/DOWN
setting buttons to select the on time you want
and press the
E
button to confirm.
4. Use the
UP/DOWN
setting buttons to select the off time you want
and press the
E
button to confirm.
5. Use the
UP/DOWN
setting buttons to select the impulse frequency
you want and press the
E
button to confirm.
6. Use the
UP/DOWN
setting buttons to select the treatment
time you want and use the
E
button to confirm.
7. Use the left and right
INTENSITY
setting buttons respectively
for
and
to select the impulse intensity you want.
8.6 Doctor’s function
The Doctor’s function is a special setting to allow you to access your
personal program even more easily and directly.
Your individual program settings are instantly recalled and activated
when the device is switched on.
You may wish to adjust this individual program following advice from
your doctor.
Setting the Doctor’s function
• Select your program and the corresponding settings as described
in section “8.2 Starting use”.
• At the start of the stimulation treatment, the impulse intensity of
and
is set to 00 by default. No impulses are sent to the
electrodes yet. Before setting the impulse intensity you want using
the intensity setting buttons, press and hold the
-
button for
5 seconds. Storage in the Doctor’s function is confirmed by a long
acoustic signal.
When you switch on the device again, the program you saved using
the Doctor’s function is automatically opened directly.
Deleting the Doctor’s function
To clear the device again and to re-allow access to other programs,
press and hold the
-
button again for approx. 5 seconds. To do
this, the impulse intensity of
and
must be set to 00. Dele-
tion of the Doctor’s function is confirmed by a long acoustic signal.
8.7 Electric current parameters
Electrostimulation devices operate with the following electric current
settings, which may affect the stimulation results differently, depen-
ding on the setting:
8.7.1 Impulse shape
This describes the time function of the electrical
impulse.
It distinguishes between monophasic and bipha-
sic pulse currents. In monophasic pulse currents,
the current flows in one direction and in biphasic
pulse currents the electrical impulse alternates its
direction.
The Digital TENS/EMS device only provides biphasic pulse currents
as these relieve muscles, cause little muscle fatigue and provide sa-
fer application.
8.7.2 Impulse frequency
The frequency indicates the number of individual
impulses per second and is displayed in Hz (Hertz).
It can be calculated by determining the cyclic value
for the time period. The relevant frequency determines which types
of muscle fibres react best. Slow-reacting fibres react more easily to
lower impulse frequencies of up to 15 Hz, whereas fast-reacting fibres
only respond from approximately 35 Hz onwards.
Impulses of approx. 45–70 Hz are linked with constant tension in the
muscles and quicker fatigue. Higher impulse frequencies are therefore
better to use for high-speed strength and maximum power training.
8.7.3 Impulse width
This indicates the duration of an individual impul-
se in microseconds. The impulse width therefore
determines, among other things, the penetration
