In case of instrument failure or malfunction, always keep
another light source in the room ready for use.
Never insert anything into the ventilation grills of the light
source. It can cause an electric shock and/or fire.
Although the illumination light emitted from the endoscope's
distal end is required for endoscopic observation and
treatment, it may also cause alteration of living tissues such
as protein denaturation of liver tissue and perforation of the
intestines through inappropriate use.
Observe the following warnings on the illumination.
-
Always set the minimum required brightness. The
brightness of the image on a video monitor may differ
from the actual brightness at the distal end of an
endoscope. Especially in combination with endoscopes
using an electrical shutter function, pay attention to the
brightness level setting of this instrument. When this
instrument is used with a video system center compatible
with automatic brightness control function, be sure to use
this function. The automatic brightness control can keep
the illumination at a proper level. Refer to the instruction
manual of the video system center for details.
-
Do not continue observation in the proximity to tissue or
keep the distal end of the endoscope in contact with living
tissue for a long time. It may cause patient burns.

As defined by the international safety standard (IEC 60601
1), 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). The part of the body
that an endoscope 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, check the current leakage classification type of
each instrument to be used for the procedure. Classification
types are clearly specified in the instruments' instruction
manuals.

Cardiac applications
.·M~@3i.
Use only the devices listed in the "System chart" in the
Appendix for endoscopic observation or treatment of the
heart or areas near the heart. Other combinations of
equipment may cause ventricular fibrillation or seriously
affect the cardiac function of the patient.
For cardiac applications, never support the endoscope with a
metal surgical arm which is not electrically isolated from the
ground. If not isolated, the endoscope will be connected to
the ground through the surgical arm and bed, and will
conduct unexpected leakage current which may seriously
affect the cardiac function of the patient.
The use of medical devices not specifically designed for
cardiac applications may cause ventricular fibrillation or
seriously affect the cardiac function of the patient. As
specified by the international standard IEC 60601-1, any
applied part" used for observation or treatment of the heart or
areas near the heart must meet "TYPE CF applied part"
requirements for low electrical leakage current. When using
endoscopes for endoscopic cardiac applications, the applied
part requirements include all devices directly connected to
the endoscope, such as the light guide cable, camera head
and telescope holder. Each of these devices must
individually meet the ''TYPE CF applied part" requirements
for leakage current limits if they are to be used for cardiac
applications.
