.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

..6Startingstimulation(runningtheprogramme)
The EMP4Expert will run the programmes after setting the inten-
sity (flashing circles)
The stimulation icons and the flashing circles identify stimulation-
run
Use the key to stop stimulation Use the ke y
to display programme parameters
Use the key to interrupt stimulation (pause)
..Stimulationduringpause
Some of the programmes contain an integrated stimulation pause
During this pause stimulation runs with a low frequency and low
intensity Intensity during this pause stimulation is 3/4 of the set
intensity

..10Manualsequencechange
A new sequence may be selected by using the modification keys
Use the key to reduce the sequence meter
Use the key to increase the sequence meter
Use the key to adopt the entered sequence
Stimulation will restart by setting intensity (setting period-flashing
cycles) whenever a new sequence is selected
..11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
..1Stoppingstimulation
Stimulation may be stopped at any time in two different ways:
Use the key to stop stimulation
The on/off key switches off the appliance and stops stimulation
..14Switchingofftheappliance
Pressing the on/off key will switch off the device
The EMP4Expert will switch itself off when no key is pressed for 3
minutes or when stimulation is not started
