.1.Changingintensityduringstimulation
During stimulation, intensity can be changed at any time by
pressing the modification keys The flashing dot belonging to the
channel becomes a circle Intensity can be varied
In programmes with an intensity modulation, the channel to be
changed is brought to the set intensity with an intensity ramp
lasting 1 second
If intensity is not changed for 5 seconds, the programme course
is continued
.1.Electroderecognition
The device constantly monitors correct connection of the electrodes
and cables If an electrode becomes detached from the skin or the
connection between the cables and the electrodes or cables and
device is interrupted, the device ends the stimulation on the corre-
sponding channel The intensity for this channel is set at 0 A short
acoustic signal indicates this process
Stimulation is also automatically stopped (acoustic signal) if inten-
sity is increased without a correctly connected electrode pair
