The range of selectable current is:
from 0 to 4 mA for impulse duration of 300 µs (or 0 to1200 nC),
from 0 to 5 mA for impulse duration of 100 µs (or 0 to 500 nC),
from 0 to 6 mA for impulse duration of 50 µs (or 0 to 300 nC).
Each delivered impulse is accompanied by a sound .
The sound has a tone increase each 0,1 mA between 1,0 and 0,5 mA .
For safety reasons it is not possible, for any current or duration, to set a current
higher than 2,0 mA (or an equivalent charge) before the needle has been
introduced in the patient (see par. 2.7.1)

is turned. In this case the figure shown corresponds to the selected figure
during the adjustment and for the following four seconds .
If the supplied current differs from the selected one by more than 0,02 mA, the
figure on the display will blink.
In case of the disconnection of the cable from the needle or the ECG electrode,
(otherwise in case of the extraction of the needle from the patient skin,) the
current will turn to zero, the display blinks and the stimulator generates a
continuous sound .
If the needle has not been inserted in the patient yet, after four seconds the
figure on the display will turn to zero (supplied current) and will start blinking
but without the alarm sound .
On the upper left part of the display, the battery indicator will illuminate and
blink if the battery charge starts to be insufficient to grant a proper functioning
of the stimulator .
Since when the low battery indicator lights on the first time, the device can still
operate for at least two hours of continuous utilization .
The display shows the selected parameters and which is the active selector for
current / charge adjustment (knob or side control).
The "P" letter lights on when the stimulator automatically passes to "Precision"
µS/MODE (see par. 2.7.6).
IThe display is used either for the
visualization of the current or charge
associated to each impulse, and for
showing the selected parameters of
functioning (duration of the impulse,
frequency, measure unit of the
visualization, active selector, and
eventual battery alarm).
The visualized figure corresponds to
the impulse actually supplied by the
stimulator, apart from when the knob
