Therapy Memory
This device will record your treatment time. To access the
therapy memory, power the device on and then press and hold

the CH2
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 CH2

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.
Impulse width
Indicates the duration of an individual
impulse in microseconds. The impulse width
therefore determines, among other things, the
penetration of the electricity; larger muscle masses usually
require larger impulse widths.
