Deleting 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.

NOTE: 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

Zeit

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

period time

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.
