trode contact. The actual setting should be effective but should never produce
any unpleasant sensations such as pain at the site of application. While a slight
tingling sensation indicates sufficient stimulation energy, any setting which leads
to pain must be avoided.
With prolonged application, readjustment may be necessary due to time
adjustment processes at the site of application.

3.5 Cycle-controlled pulse parameter variation

In many cases it is necessary to cover the entirety of tissue structures at the
site of application by using several pulse parameters. With the Digital TENS/
EMS unit, this is done by the existing programmes automatically making a
cyclical pulse parameter change. This also prevents individual muscle groups
at the site of application from getting tired.
With the Digital TENS/EMS unit there are useful presettings for current
para meters. During the application, however, you do have the possibility of
changing pulse intensity at any time and, with individual programmes, you
can also alter pulse frequency beforehand in order implement the application
which is the most comfortable or promises the most success for you.

4.2 Key functions

Every time a key is pressed, this is acknowledged by a signal tone in order to
ensure that any unintentional pressing of a key is detected. This signal tone
