• The HF equipment, when applied to a patient with a
pacemaker implanted, may cause malfunctioning or failure of
the pacemaker and may seriously affect the patient. Always
confirm that it is safe to proceed with a cardiologist and the
manufacturer of the pacemaker before proceeding.
• To prevent shock hazards, never apply the PSD-30 to the
heart in combination with TYPE B or TYPE BF applied parts.
• When using the electrosurgical unit on or in the vicinity of the
heart, be sure to use it with the minimum necessary output.
Spark discharge during operation may affect the heart.
• Never install or operate the electrosurgical unit in locations
where:
−the concentration of oxygen is high.
−oxidizing agents (such as nitrous oxide (N2O)) are present
in the atmosphere.
−flammable anesthetics are present in the atmosphere.
−flammable gases are present in the atmosphere.
Otherwise, explosion or fire may result and cause damage to
human body. Because this electrosurgical unit is not
explosion-proof.
• The PSD-30 has been designed for flexible endoscopic
applications. Therefore, do not use it for surgical operations.
• Always use the S-cord when endoscopic treatment is
performed with an endoscope equipped with the S-cord
connector mount. When using an endoscope without the
S-cord connector mount, refer to the instruction manual and
confirm that the electrosurgery is feasible with this
endoscope. If the electrosurgical unit is used in conjunction
with an endoscope that is not feasible with the
electrosurgery, a burn to the patient, the operator or the
assistant may occur.
• If the electrosurgical unit fails and the output is stopped
during treatment, it may be impossible to continue treatment
due to adhesion of the endo-therapy accessory to a mucous
tissue or other accident. Prepare a spare electrosurgical unit
as backup to ensure that the procedure can be completed
without complication in case of a malfunction.

ELECTROSURGICAL UNIT PSD-30
• 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
a metal clip or other accessories. The tissue around the
metal clip or the accessory may be burned.
• To prevent electric shock, the electrosurgical unit is designed
to function with insulated connectors that have Type CF
electromedical equipment classifications (A-cord, P cord,
P plate, S-cord). Therefore, to prevent shock caused by
leakage current from other electrical equipment applied to
the patient, the connectors from the other equipment should
not be grounded.

• Should any abnormal output be suspected during operation,
immediately terminate the use of the equipment and turn
OFF the electrosurgical unit.
• To prevent operator shock, electrosurgical unit malfunction
and electrosurgical unit damage, keep liquids away from all
electrical equipment. If liquid gets on or into the
electrosurgical unit, terminate operation immediately and
contact Olympus.
• To prevent patient burns, the patient’s skin surfaces should
not touch each other (e.g. bare arm and side of chest) or any
metal items in the procedure room. Remove any metallic
items from the patient (wristwatches, jewelry, etc.) before
starting the procedure.
• To prevent patient burns, the patient’s clothes must be dry.
• To prevent operator and assistant burns, be sure to wear
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.

• 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.

• Flammable agents used for cleaning and disinfection must be
allowed to evaporate before the electrosurgical unit is used.
Also ensure that flammable solutions are neither on the
patient’s skin nor in the patient’s body cavity when the
electrosurgical unit is used.
• To prevent patient burns when the electrosurgical unit is used
in conjunction with a non-Olympus electrosurgical unit,
ensure that each unit is supplied with power from wall mains
outlets. Also ensure that each unit is supplied with power
from separate breakers.
• During operation, temporarily unused electrodes should be
stored in an electrically insulated container. Unused
electrodes should never be placed on the patient otherwise it
may cause operator and/or patient burns.
• The electrosurgical unit should not be used for performing
circumcisions.
• To prevent patient burns, never use cords with scratches or
cracks.
• Studies have shown that smoke generated during
electrosurgical procedures can be irritating and potentially
harmful to surgical personnel. These studies recommend the
use of surgical masks and adequate ventilation of smoke by
the use of surgical smoke evacuators or other means.
