Dangers, warnings and notes
Follow the dangers, warnings and notes given below when handling this
instrument. This information is to be supplemented by the dangers, warnings
and cautions given in each chapter.
• Strictly adhere to the following precautions. Failure to do so
may place the patient and medical personnel in danger of
electric shock.
When this equipment is used to examine a patient, do not
allow the metal parts of the endoscope or its accessories
to touch metal parts of other system components. This
instrument is electrically connected to the metal parts of
other system components and such contact may cause
unintended current flow to the patient.
Keep liquids away from all electrical equipment. If liquid
enters the unit, stop the operation of the equipment at
once and contact Olympus.
Do not prepare, inspect or use this equipment with wet
hands.
• Never install and/or operate the OTV-S7V 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.
Otherwise, explosion and/or fire can result.
• Be sure to prepare another video system center to avoid that
the examination must be interrupted due to equipment failure
or malfunction.
• 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 by inappropriate using.
Observe the following warnings on the illumination.

Important Information — Please Read Before Use
9
VISERA VIDEO SYSTEM CENTER OTV-S7V
Always set the minimum required brightness.
The brightness of the image on a video monitor may differ
from actual brightness at the distal end of endoscope.
Especially, operating the electrical shutter function of this
instrument, pay attention to the brightness level setting of
the light source. When this instrument is used with a light
source with the automatic brightness control function, be
sure to use the function of the light source. The automatic
brightness control function can keep the illumination light
properly. Refer to the instruction manual of the light
source for details.
Do not continue observation in proximity to tissue or keep
the distal end of the endoscope in contact with a living
tissue for a long time.
When discontinuing the use of the endoscope, be sure to
turn the light source OFF or activate the light shield
function (standby mode etc.) so that the endoscope does
not irradiate unnecessary light.
• This product may interfere with other medical electronic
equipment used in combination with it. Before use, fully
confirm the compatibility of this instrument with all equipment
to be used with it.
• Do not use this product in any place where it may be subject
to strong electromagnetic radiation (for example, in the
vicinity of a microwave therapeutic device, MRI, wireless set,
short-wave therapeutic device, cellular/portable phone, etc.).
This may impair the performance of the product.
• If the endoscopic image dims during use, this may be a sign
that blood or mucus is adhering to the light guide on the distal
end of the endoscope. Carefully withdraw the endoscope
from 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.

VISERA VIDEO SYSTEM CENTER OTV-S7V
Cardiac applications
• Use only the devices listed in the “System chart” 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 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 metal endoscopes for endoscopic cardiac applications,
the “Applied Part” requirements include all devices directly
connected to the endoscope, such as the light guide (LG)
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.
• The OLYMPUS LG cables and camera heads listed in the
“System chart” (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.
