Intended use
This video system center has been designed to be used with OLYMPUS camera heads, endoscopes,
light sources, monitors, EndoTherapy accessories, and other ancillary equipment for endoscopic
diagnosis, treatment, and video observation.
Applicability of endoscopy and endoscopic treatment
If there is an official standard on the applicability of endoscopy and endoscopic treatment that is
defined by the hospital’s administration or other official institutions such as academic societies on
endoscopy, follow that standard. Before starting endoscopy and endoscopic treatment, thoroughly
evaluate its properties, purposes, effects, and possible risk (their natures, extent, and probability).
Perform endoscopy and endoscopic treatment only when its potential benefits are greater than its
risks.
Fully explain to the patient the potential benefits and risks of the endoscopy and endoscopic treatment
as well as any examination/treatment methods that can be performed in its place, and perform the
endoscopy and endoscopic treatment only after obtaining the consent of the patient.
Even after starting the endoscopy and endoscopic treatment, continue to evaluate the potential
benefits and risks, and immediately stop the endoscopy/treatment and take proper measures if the
risks to the patient become greater than the potential benefits.

Terms used in this manual
Light source:
The light source provides light and electrical signals to the endoscope. It also provides
electrical signals to the video system center.
Video converter:
The video converter and video system convert a fiberscope image to a video signal which
can be viewed on the monitor.
Camera head:
The camera head is a device that converts endoscopic images from a fiberscope or rigid
endoscope into monitor images.
Video printer:
The video printer is a device that prints the frozen video image.
Wall mains outlet:
The wall mains outlet is a wall AC mains power outlet socket having the exclusive terminal
for grounding.
Isolation transformer:
The isolation transformer is a safety device that is used to isolate the noninsulated
equipment with potentially high leakage currents to decrease the possibility of electric
shock.
Automatic brightness adjustment:
The automatic brightness adjustment automatically adjusts the intensity of the light emitted
from the light source so that the endoscopic image will be maintained at constant
brightness even if the distance between the distal end of the endoscope’s insertion tube
and the subject changes.
Image sensor (CCD):
The image sensor (CCD) is a device that converts light into electrical signals.
CV-190 INSTRUCTION MANUAL

Important Information — Please Read Before Use
Electronic shutter:
The electronic shutter function changes the exposure time of the image sensor so that the
brightness of an image is maintained on the video monitor.
Iris:
The iris function is used to electrically measure the brightness of an endoscopic image to
obtain a control signal for the purpose of automatic light adjustment.
Color adjustment:
Color adjustment adjusts the color balance and the chroma on the monitor.
Freeze:
The freeze function creates a stationary view of the moving image.
Release:
The release function is used to capture and record an endoscopic image.
Edge enhancement:
Edge enhancement is an image processing technique that electronically sharpens the
edges of an image.
Structure enhancement:
Structure enhancement is an image processing technique that electronically emphasizes
the detailed patterns and edges of an image to increase sharpness.
AGC (automatic gain control):
The AGC is used to increase the brightness of an endoscopic image electrically when the
brightness of the image is dark because the distance between the endoscope’s distal end
and the object is too long.
PIP (Picture in Picture):
PIP function displays the image of the endoscopic live image and the image of an external
device on the monitor simultaneously, where one image is embedded into the other image.
POP (Picture out Picture):
POP function displays the image of the endoscopic live image and the image of an
external device side by side on the monitor simultaneously.
Annotation
A recorded frozen image is displayed with comments and a title. Up to 4 images can be
displayed on the monitor at once.

WARNING
• In case of video system center failure or malfunction, always keep another video
system center in the room ready for use.
• Never insert anything into the ventilation grills of the video system center. 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 biological tissue and
perforation of the intestines by 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 electronic
shutter function, pay attention to the brightness setting of the light source. When
the video system center is used with a light source compatible with automatic
brightness control function, be sure to use this function. The automatic
brightness control function can keep the illumination light adjusted properly.
Refer to the instruction manual for the light source for details.
Do not continue observation in 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.
When discontinuing the use of the endoscope, be sure to turn the light source
OFF.
• This product may interfere with other medical electronic equipment used in
combination with it. Before use, refer to the Appendix to confirm the compatibility of
the video system center with all equipment to be used.
• Do not use the video system center in any place where it may be subject 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 have
adhered to the light guide on the distal end of the endoscope. Carefully withdraw
the endoscope from the patient and remove the blood or mucus 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 the video system center and/or other instruments
connected. Otherwise, damage and/or malfunction can occur.
• Do not connect or disconnect the endoscope, videoscope cable, video converter, or
camera head while the video system center is turned ON. Connecting or
disconnecting the endoscope while the video system center is ON may destroy the
CCD. Turn the video system center OFF before connecting or disconnecting the
endoscope.
• Clean and vacuum dust from the ventilation grills using a vacuum cleaner, when
necessary. Otherwise, the video system center may break down and get damaged
from overheating.
• Be sure that the video system center is not used adjacent to or stacked with other
equipment (other than the components of the video system center or system) to
avoid electromagnetic interference.
• Electromagnetic interference may occur to the video system center when it is
placed near equipment marked with the following symbol or other portable and
mobile RF communications equipment such as cellular phones. If radio
interference occurs, mitigation measures may be necessary, such as reorienting or
relocating the 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 357 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.
NOTE
• The Olympus light guide cables and camera heads listed in “ System chart” on
page 357 (TYPE CF applied part) which are suitable for cardiac applications bear a
mark.
• The Olympus surgical holder for telescope (SH-1) has an electrically isolated arm
structure which isolates the endoscope from the ground. This design makes the
SH-1 suitable for cardiac applications.
