Important Information--Please Read Before Use
DANGER
S Any applied part except “TYPE CF APPLIED PART” must
never be applied directly to the heart and must not be used
in procedures involving cardiac observation or surgery.
Leakage current from any applied part except “TYPE CF
APPLIED PART” 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 any applied
part except “TYPE CF APPLIED PART” to the heart or
any area near the heart.
-- Never allow an accessory or another endoscope, which
is in contact with the heart (or an area near the heart) to
contact the endoscope connected to any applied part
except “TYPE CF APPLIED PART”.
-- For cardiac applications, use only the instrument
bearing the “TYPE CF APPLIED PART”. Only CF
symbol mark “
” bear on the applied part.
Refer to the instruction manual of the camera head or
light guide cable for system configuration requirements.
S Strictly adhere to the following precautions. Failure to do so
may place the patient and medical personnel in danger of
electrical 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 fluid
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.
S Never install and/or operate the OTV-SC 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.

Important Information--Please Read Before Use
WARNING
S In the event of instrument failure or malfunction, always
keep another Video System in the room ready for use.
S 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.
-- 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.
Pay attention to the brightness level setting of the light
source. 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.
S If the endoscopic image dims during use, this may be a sign
that blood or mucus is adhered to the light guide on the
distal end of 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
examination. If you continue to use the endoscope in such
a condition, the distal end temperature may rise and cause
mucosa burns. It may also cause patient and/or operator
injury.
S The system should be establish with equipment complied
with relevant EMC standards For safety reason.
S Equipment which do not comply with EMC standard may
cause interference and its function or performance may be
affected.
S Portable or mobile phones may influence the medical
electrical equipment by their emitting energy.
