and cautions given in each chapter.
•
As a Type BF applied part, this instrument must never be
applied directly to the heart and must not be used in
procedures involving cardiac observation or surgery.
Leakage current from Type BF applied parts may be
dangerous and cause ventricular fibrillation or otherwise
seriously affect the cardiac function of the patient.
Accordingly, always adhere to the following:
Never apply the endoscope connected to this instrument
to the heart or any area near the heart.
Never allow accessories or another endoscope, which is
in contact with the heart (or an area near the heart) to
contact an endoscope connected to this instrument.
•
Strictly observe the following precautions. Failure to do so
may place the patient and medical personnel in danger of
electric shock.
When using this equipment, make sure that the metal
parts of the endoscope, accessories or camera do not
come in contact with metal in the area or in other system
components. Metal-to-metal contact can create an
electrical connection and cause current to flow
unintentionally to the patient (leakage current, for
example).

Important Information — Please Read Before Use
As defined by the international safety standard (IEC 60601-1:
1988), medical electrical equipment is classified into the
following types: Type CF applied part (the instrument can
safely be applied to any part of the body, including the heart),
and Type B/BF applied part (the instrument can safely be
applied to any organ except the heart). Which part of the
body a videoscope or electrosurgical accessory can safely
be applied to depends on the classification of the equipment
to which the instruments are connected. Before beginning
the procedure, review the current leakage classification type
of each instrument that you will use for the procedure.
