Side Control

The side control buttons can be activated by pressing and holding
on the arrow the for at least 2 sec .
Its activation exclude the rotating knob from the possibility to
adjust the current / charge: on the display this condition is
highlighted by the disappearing of the symbol
of the symbol .
The side control takes over the function of the rotating knob: each pressure on
the arrow part of it corresponds to a clockwise step of the knob; each pressure
on the lower part of it corresponds to an anticlockwise step of the knob .
Keeping the lower or the upper button of the side control pressed, the current
/ charge will be adjusted continuously .
The utilization of the side control is particularly useful when the stimulator is
used within a sterile field, with its protection bag (supplied separately), or for
one hand manipulation .
Once the side control is activated, in order to deactivate it the stimulator must
be switched off .

Safety features

2.7.1 Current self limitation at switching on

For safety reasons, the stimulator will not permit excessive currents before the
needle has been inserted into the patient . Therefore, independently from the
selected duration of the impulse, it will not be possible to initially set a current
higher than 2,0 mA (or an equivalent charge).
Once the needle has been inserted into the patient, it's possible to select
currents higher than 2,0 mA, as described in par . 2 . 4 .
2.7.2 Sound tones
I
The stimulator generates a sound synchronized to the electrical
impulse supplied to the patient (then at the selected frequency)
The tone of this sound remains unchanged for any current higher
than 1,0 mA (or equivalent charge values)
When the current setting is reduced the sound increases by one
tone each 0,1 mA of reduction up to 0,5 mA (highest tone).
For currents lower than 0,5 mA (or equivalent charge), the reached
tone keeps unchanged .
From the menu of set up modification (point 2.3) it is possible to disactivate
the sound during normal functioning . In that case the symbol will be crossed .
If the sound tone has been deactivated, check the
display to make sure that the current is effectively
supplied to the patient.
It is not possible to disactivate the alarm sounds .
