 Attach the neutral electrode over the entire contact surface evenly.
Secure reusable neutral electrodes with rubber bands or elastic straps
so that they do not loosen when the patient moves. Ensure that the
patient’s circulation is not impaired (risk of necrosis).
 Never use wet clothes or conductive pastes.
 Ensure that no liquids (e.g. cleaning fluids, disinfectants, blood or
urine) penetrate between the patient and the neutral electrode.
 Do not place the neutral electrode under the patient’s buttocks or
back.
 Ensure that there are no ECG electrodes in the current path of the HF
device.
 Check the neutral electrode before and after use for damage and to
ensure that they are working properly.
Replace defective accessories immediately
Example application using a disposable electrode
 Remove the protective film and attach the self-adhesive disposable
electrode to the patient. Ensure that the long edge of the disposable
electrode faces the operation site and the electrode is fully in contact
with the skin. This avoids excessive current concentration on the short
edge.
 Using both hands, press the self-adhesive disposable electrode firmly
against the patient’s skin.
 Clamp the electrode tab to the neutral electrode cable.
 After the operation, remove the disposable electrode carefully to avoid
skin damage.
With a one-piece neutral electrode
 Check the one-piece neutral electrode during surgery.
 Ensure that the one-piece electrode is not blocked at the device.
With a split neutral electrode
 Apply the split neutral electrode correctly and without any additional
objects, as otherwise the HF device may detect a path between the
two sections due to other objects.
 See that the current flows equally to both parts of the split neutral
electrode.
 When the EASY indicator is illuminated yellow, heating at the current
exit point may be present depending on the indication.
See Section EASY neutral electrode monitoring (EASY monitoring) , page 35
regarding monitoring of the neutral electrode.
