Important Information — Please Read Before Use
• Always have a defibrillator ready in case of a cardiac
emergency. During operation of the defibrillator, remove the
endoscope from the patient.
• To respond to possible patient bleeding, prepare at least the
following three hemostatic procedures: coagulation, clipping
and local injection.
• To prepare for possible accidents, emergency equipment for
life-saving, intubation and appropriate pharmaceuticals
should be located in or near the procedure room.
• Never attach the patient plate in the vicinity of a metal
implant. The tissue in the vicinity of the metal implant may be
burned.
• Keep the electrosurgical unit and ancillary cords (A-cord,
P cord, S-cord) as far away as possible from other
electromedical equipment and cords. If placed too close, high
frequency signals or spark discharge noise from the
electrosurgical unit may interfere with the operation of other
equipment.
• To prevent patient burns, the electrosurgical unit and ancillary
cords (A-cord, P cord, S-cord) should not come in contact
with the patient or metal parts of the operating table.
Furthermore, patients should also keep away from metallic
parts of the operating table or other devices.
• Never loop the cords (A-cord, P cord, S-cord) or bundle
cords together with cords belonging to other medical
equipment. The high frequency signals or spark discharge
noise generated by the electrosurgical unit may interfere with
the operation of other medical equipment.
• The electrosurgical unit may interfere with electromedical
equipment used in conjunction with it. Before use, thoroughly
confirm the compatibility of all the equipment.
• Do not bring the tip of the electrosurgical accessory close to

starting the procedure.
chemical-resistant gloves during operation.
• If the intestines contain a flammable gas, replace this gas
with air or a non-flammable gas before performing the
operation, to minimize the risk of fire or explosion.
• The endoscopic treatment performed should not include a
therapy with which part of the treated tissue (poly head, etc.)
or part of the endoscope distal end or endo-therapy
accessory is in contact with or close to normal tissue.
Otherwise, current flows to the normal tissue through the part
of the treated tissue, the metallic parts at the endoscope’s
distal end or endo-therapy accessory and may cause burns.
• Be sure that the distal end of endoscope or accessory does
not contact bridging fluids surrounding the target tissue.
Electric current may flow to the surrounding normal tissue via
the fluids and cause burns.
• Never grasp the target tissue with non-insulated grasping
forceps. Non-insulated grasping forceps will disperse the
electric current and normal operation may be impeded.
• To ensure electrical safety, the electrosurgical unit should not
be used in conjunction with:
− Electrical equipment whose safety against leakage
current is not guaranteed.
− Electrosurgical equipment whose safety in combined use
is not guaranteed.

Important Information — Please Read Before Use
• If the electrosurgical unit is used in conjunction with a
non-Olympus electrosurgical unit, keep the electrosurgical
accessory away from the target area while the electrosurgical
unit is in operation. Do not activate output of both units
simultaneously. Patient or operator injury may occur due to
the concentration of electric current.
• When using an electrocardiograph or other physiological
monitoring equipment simultaneously with the electrosurgical
unit on a patient, any monitoring electrodes should be placed
as faraway as possible from the electrodes and patient plate
used with the electrosurgical unit. If placed too close, high
frequency signals or spark discharge noise from the
electrosurgical unit may interfere with the operation of an
electrocardiograph or other physiological monitoring
equipment. Needle monitoring electrodes should not be
used, as they may cause patient burns. Physiological
monitoring equipment incorporating high frequency current
limiting devices is recommended.
• Use physiological monitoring equipment throughout the
entire procedure, for continuous observation of the patient’s
condition.
• The open-circuit voltage output characteristics of the
electrosurgical unit are shown below. When setting the
output level, first set it to a low output level and increase it
gradually. If the output is initially set to an excessive level, the
electrode’s insulation could be damaged, which could cause
operator and/or patient burns. Furthermore, it is
recommended that you perform basic experiments before
using the electrosurgical unit. If the instruction manual for the
endoscopic accessory to be used stipulates a rated voltage,
the output should be set so that it does not exceed that
voltage.
