2. SAFETY
WARNING
These operating instructions form an integral part of the equipments and must be available to the operating
personnel at all times. All the safety instructions and advice notes are to be observed. Be sure that these operating instructions
is furnished together the equipment when this is tranferred to other operating people. Electrosurgery can be dangerous.
Careless use of any element in the electrosurgical system may subject the patient to a serious burn.
Read and understand all warnings, precautions, and directions for use before attempt to use any active electrode. Neither
LED S.p.A., Frosinone, Italy nor any of the subsidiary sales organisations can be considered responsible for personal,
material or consequential injury, loss or damage that results from improper use of the equipment and accessories.
2.1 GENERAL
Persons fitted with a heart pacemaker must not operate the equipment nor approach the same while it is in operation.
Do not use the dispersive plate if the conductive adhesive has become dry.
Do not reuse the disposable dispersive plate.
Prior to place the dispersive plate clean, shave and dry the body's area.
The whole surface of the dispersive plate must be placed on a well vascularized muscle as next as possible to the surgical
area.
The patient does not must be in contact with metal parts that are connected to the earth or have a large electrical
coupling capacity to the earth (for example: operating-table or metallic support). The use of antistatic sheets is advised.
Avoid the skin to skin contact (for example between arm and body of the patient). Insert an interface material like dry
urgical gauze.

When high frequency electrosurgical unit and phisiological monitoring devices are used at a time in the same patient, all
the monitoring electrodes, that has not resistive or inductive elements suitable to high frequency interferencies, must be
as far as possible from the electrodes of the electrosurgical unit.
Avoid the use of monitoring needles.
The connection to the electrodes should be located in such a way to avoid the contact both with the patient and with
other cables.
The use of bipolar technique is recommended for surgical operation in regions of the body with relatively small section
so to avoid unwanted coagulation.
The power level should be the lowest useful to the work to do.
Always check the dispersive plate when ever the electrosurgical unit fails to produce the desired effect.
Reason for a low output power level, or for an uncorrect functioning of the electrosurgical unit when arranged for a
normal output, may be lack of connection of the dispersive plate or its imperfect placement.
The use of flammable anesthetics, of oxygen and of nitrogen protoxyde should be avoid in the case of operation at the
head or at chest level except the possibility of evacuating gas.
Flammable materials used to clean, or to disinfect, should be let to evaporate before the use of the electrosurgical unit.
There is risk of stagnation of flammable solutions under the patient or in body cavities as the umbilicus and the vagina.
The fluid which deposits in these areas should be removed before the equipment use. The danger of endogenous gas
ignition has to be considered.
Some materials like cotton wool or gauze, when saturated with oxygen, may burst into flames because of the sparks
produced by the equipment in the normal use.
There is a risk for the patients fitted with heart pace-maker, or other stimulation electrode: an interference may occur
with the stimulator signal or the stimulator itself can be damaged. Please refer to the cardiologic department when in
doubt.
The use of electrosurgery is not recommended in patients:
with serious unbalance of arterial pressure
