the Doctor’s Function
To clear the device and allow access to other programs again, press and hold the ˅ button again for about five seconds. To
do this, the impulse intensity of and must be set to 00.
Deletion of the Doctor’s function is confirmed with a long beep.
Therapy Memory
This device will record your treatment time. To access the therapy memory, power the device on and then press and hold the ˄
button for five seconds. The elapsed treatment time appears in the display. The top two numbers are the minutes, with the hours
shown underneath. To reset the treatment time, press and hold the ˅ button for five seconds. When replacing the battery, the
therapy memory is reset. Press the Menu button to return to selecting a program, or shut the device off.

OTE: Therapy memory cannot be accessed if the Doctor‘s Function is activated.
12. Current Parameters
Electrostimulation units operate with the following current settings that may affect stimulation effects differently:
Impulse shape
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 direction. The digital EMS/TENS unit only provides biphasic pulse currents as
these relieve muscles, cause little muscle fatigue, and provide safer application.
Impulse frequency
Indicates the number of impulses each second and is shown in Hz (Hertz). It can be calculated by determining
the cyclic value for the time period. The relevant frequency determines which types of muscle fibers react
favorably. Slow-reacting fibers react more easily to lower impulse frequencies up to 15 Hz, whereas fast-
reacting fibers only respond from approximately 35 Hz and up. Impulses around the 45-70 Hz range are linked with constant
muscle tension and quicker fatigue. Higher impulse frequencies are therefore favorable in strength and maximum power
training.
