The unit stores the detected error codes to help the Technicians in finding a solution for the problems. The
procedure to perform the related control is detailed in the Service Manual.
BECAUSE OF THE PREVIOUS REASONS, DURING THE USE
Users must not both increase too much the power and think that the problem depends on the unit:
If the unit doesn’t deliver the power (The normal powers appear less efficacious), but it has properly
passed the auto
‐
check at the switching on and the systems do not signal problems.
Users must check:
The good contact between the neutral electrode and patient’s tissues while using monopolar currents.
The conditions of cables and connectors, by bending and pulling them.
(They mainly break close to the instrument).
The assembly and the internal connections of all instruments, mainly if for endoscopy or laparoscopy.
The insulation of the blades of all bipolar scissors. (The continuous sliding damages it and causes a
short circuit which does not allow the current to reach tissues).
Users must clean:
The tips of all electrodes and instruments (If dirty, the current doesn’t reach tissues).
The
joints of the bipolar instruments for laparoscopy (If dirty the current doesn’t reach tissues).

INITIALS CHECKS AND EQUIPOTENTIAL CONNECTION
Verify that the mains power supply corresponds to the technical data (see the data label on the back).
Connect the unit to the mains supply with the mains switch (C, green
‐
on the back) off.
To perform, if needed, the equipotential connection, use the specific plug (E
‐
on the back).
DATA STORING AT THE SWITCHING ON
The unit always re

sets at the switching on, intentional or caused by a temporary loss of supply, the settings used
at the switching off. It does not maintain the following:
The selection of the
AUTO SOFT MICRO BICOAG
and
AUTO SEALING
bipolar currents with automatic
“impedance sensing”
start/stop. (IEC Standards establish that a current with automatic start/stop system
has to be intentionally selected by users at the switching ON)
If the memory number is blinking at the switching OFF, it blinks again at the following switching ON and the unit
resets the same setting. About the blinking of the memory number see the Par
“BLINKING OF A MEMORY
NUMBER.
CHECK OF THE HF LEAKAGE CURRENTS TO EARTH
All HF currents also generate leakage currents to earth which, according to the safety standards for the
electrosurgical devices, have to be lower than 150 mA to reduce the risk of burns on patient’s tissues. The unit is
provided with a specific circuit which checks these currents and, if they go over the allowed limit, intervenes as
follows:
It automatically reduces the output power (These currents depend on the power)
