incremental step. The presently selected intensity of the stimulation current is indicated on the LCD.
This specifi ed value will only correspond with the actually emitted stimulation current, if the electrical
stimulation circuit is properly closed over the patient. In this case, the selected stimulation current (set
point), which is shown on the display, corresponds exactly to the stimulation current actually fl owing
through the electrical circuit of the patient. This correct function is indicated by the »
⫽
« symbol. As
soon as the selected stimulation current differs from the actually fl owing stimulation current , the »

symbol will appear on the display. Please note, that in this case the current actually fl owing through
the patient might be lower than the desired stimulation current which you have previously selected.
An increase of the selected stimulation current might therefore not effect the stimulation current
actually fl owing through the patient. If this happens, it is absolutely necessary to reduce the nominal
stimulation current, and to discover the cause of the inadequate or missing patient connections. Do
not increase the nominal stimulation current under any circumstances before the reason for the faulty
current fl owing through the patient has been identifi ed clearly and has been remedied.
4.8 Display modes for stimulation current
The adjusted value (PRESET value) is indicated on the LCD, as the intensity of the stimulation current is
adjusted by turning the knob. If the knob is not turned anymore, the device will automatically switch to
indicating the intensity of the stimulation current actually fl owing through the patient (ACTUAL value).
During the indication of the actually fl owing current, a symbol resembling a human being is addition-
ally displayed on the LCD on the left-hand side of the current intensity.

4.9 Display of the ACTUAL resistance, patient resistance
The current ACTUAL resistance (patient resistance) is shown in analog representation with the aid of
two bar graphs at the bottom edge of the display.

An acoustic warning (double sound) is additionally emitted when specifi c limits are exceeded
(SETUP Level 4)
4.10 Indication of the battery condition
The battery condition is permanently shown on the display by indicating the remaining utilizable bat-
tery capacity. Each of the fi ve segments represents 20% of the battery capacity. This means: if all fi ve
segments are visible, then 100% of the utilizable battery capacity are available, if no segment is vis-
ible, then 0% capacity is available. If there are only 20% of the battery capacity available, the battery
condition indicator will start to fl ash. Then the battery should be replaced soon, or a substitute battery
should be kept at hand for replacement. If no segment is visible anymore, the device will emit acous-
tic warning signals, as the battery-symbol is fl ashing. If the battery capacity falls even lower, then the
device will shut down automatically for reasons of safety.
4.11 Adjustment of the stimulation impulse bandwidth
Pressing this button will activate a program option which allows you to preset the stimulation
impulse bandwidth. The current intensity value and the mA-dimension will disappear from the
display. Now the stimulation impulse bandwidth indicated in the upper right-hand corner of
the display can be adjusted to one of the following values with the aid of the turning-knob:
