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
Doctor's function is confirmed by a long acoustic signal.
Therapy memory
EM 59 Heat records the treatment time. To access the therapy memory,
switch the device on using the ON/OFF
button for 5 seconds. The treatment time elapsed appears in the
display. The top two numbers stand for minutes; the hours are shown
below. To reset the treatment time, press and hold the
5 seconds. Press the "Menu" button to return to selecting a program, or
switch the device off. Info: Therapy memory cannot be accessed if the
Doctor's function is activated.
12. ELECTRIC CURRENT PARAMETERS
Electrostimulation devices operate with the following electric current set-
tings, which may affect the stimulation results differently, depending on
the setting:
12.1 Impulse shape
This describes the time function of the electrical im-
pulse.
It distinguishes between monophasic and biphasic
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 EMS/TENS unit only provides biphasic pulse currents as these
relieve muscles, cause little muscle fatigue and provide safer application.
12.2 Impulse frequency
The frequency indicates the number of individual im-
pulses per second and is displayed in Hz (Hertz). It
can be calculated by determining the cyclic value for
must be set to 00. Deletion of the
button and press and hold the
button 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 mus-
cles and quicker fatigue. Higher impulse frequencies are therefore better
to use for high-speed strength and maximum power training.
12.3 Impulse width
This indicates the duration of an individual impulse
in microseconds. The impulse width therefore de-
termines, among other things, the penetration of the
electricity, where usually larger muscle mass requires
a larger impulse width.
12.4 Impulse intensity
Setting the intensity level depends on the individual
sensitivity of each user and is determined by a variety
of variables, such as site of application, blood supply
to the skin, skin thickness and the quality of the elec-
trode contact. The settings should be effective but should never cause
an unpleasant sensation, such as pain at the site of application. While a
gentle tingling indicates sufficient stimulation energy levels, any setting
that causes pain should be avoided.
When using the device for an extended period, you may need to adjust the
Time
intensity level, as your muscles may start to adapt to the impulse intensity.
12.5 Cycled impulse parameter variation
In many cases it is necessary to cover the overall tissue structure at the
site of application by applying several impulse parameters. In the digital
EMS/TENS unit, this is achieved by the provided programs, which auto-
matically make a cyclical impulse parameter change. This also prevents
individual muscle groups at the site of application being affected by fa-
tigue.
The digital EMS/TENS unit provides sensible default current parameter
settings. With this, you can change the impulse intensity at any time dur-
