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.
Deletion of the 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 and
press and hold the 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
˅
button for 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.
10. Electric current parameters
Electrostimulation devices operate with the following electric
current settings, which may affect the stimulation results differently,
depending on the setting:
10.1 Impulse shape
This describes the time function of the electrical
impulse.
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.
10.2 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.
10.3 Impulse width
This indicates the duration of an individual
impulse in microseconds. The impulse width
therefore determines, among other things, the
penetration of the electricity, where usually larger
muscle mass requires a larger impulse width.
10.4 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 electrode 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 intensity level, as your muscles may start to adapt to the
impulse intensity.
