burns.
When discontinuing the use of the endoscope, be sure to turn the light source
OFF.
• This video system center may interfere with other medical electronic equipment
used in combination with it. Before use, refer to the “Appendix” to confirm the
compatibility of this video system center with all equipment to be used.
• Do not use this video system center in locations exposed to strong electromagnetic
radiation (for example, in the vicinity of a microwave therapeutic equipment, MRI,
wireless set, short-wave therapeutic equipment, cellular/portable phone, etc.). This
may impair the performance of the video system center.
• If the endoscopic image dims during use, blood, mucus or debris may adhere to the
light guide on the distal end of the endoscope. Carefully withdraw the endoscope
from the patient and remove the blood or mucus in order to obtain optimum
illumination and to ensure the safety of the examination. If you continue to use the
endoscope in such a condition, the distal end temperature may rise and cause
mucosal burns. It may also cause patient and/or operator injury.
• Do not rely on the optical-digital observation method alone for primary detection of
lesions or for a decision regarding any potential diagnostic or therapeutic
intervention.

WARNING
• For reasons described below, do not rely on the NBI observation modality alone for
primary detection of lesions or to make a decision regarding any potential
diagnostic or therapeutic intervention.
• To display endoscopic images, connect the output terminal of the video system
center directly to the monitor. Do not make the connection via any ancillary
equipment. Images may disappear during observation depending on the condition
of the ancillary equipment.
• The SDI signal is transmitted by daisy-chaining (chaining in a row) several devices.
If one of the devices is turned OFF, the SDI signal is not transmitted to the rest of
them.
CAUTION
• Do not use a pointed or hard object to press the buttons on the front panel and/or
keyboard. This may damage the buttons.
• Do not touch the electrical contacts inside the video system center’s connectors.
• Do not apply excessive force to this video system center and/or other instruments
connected. Otherwise, damage and/or malfunction can occur.
• Do not connect or disconnect the endoscope or camera head while this video
system center is turned ON. Connecting or disconnecting the endoscope while this
video system center is ON may damage the CCD. Turn the video system center
OFF before connecting or disconnecting the endoscope.
• Clean and vacuum dust the ventilation grills using a vacuum cleaner, when
necessary. Otherwise, the video system center may break down and gets damaged
from overheating.
• Be sure that this video system center is not used adjacent to or stacked with other
equipment (other than the components of this video system center or system) to
avoid electromagnetic interference.
• Electromagnetic interference may occur to this video system center when it is
placed near equipment marked with the following symbol or other portable and
mobile RF (Radio Frequency) communications equipment such as cellular phones.
If radio interference occurs, mitigation measures may be necessary, such as
reorienting or relocating this video system center or shielding the location.

NOTE
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
DANGER
• Use only the devices listed in “ System chart” on page 293 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
that 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 that 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.
NOTE
• The light guide cables and camera heads listed in “ System chart” on page 293
(TYPE CF applied part) that are suitable for cardiac applications bear a
mark.
• The surgical holder for telescope (SH-1) has an electrically isolated arm structure
that isolates the endoscope from the ground. This design makes the SH-1 suitable
for cardiac applications.
