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,
cautions and notes given in each chapter.
• Strictly adhere to the following precautions. Failure to do so
may place the patient and medical personnel in danger of an
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
immediately and contact Olympus.
Do not prepare, inspect or use this equipment with wet
hands.
• Never use this instrument in the presence of flammable
substances or in an environment with a high concentration of
oxygen, and keep all flammable gases and liquids away from
this instrument while it is being used. Explosion or fire may
result because this instrument is not explosion-proof
construction.
• This instrument produces significant heat due to the high
intensity light required for endoscopic procedures. If the distal
end of an endoscope and/or the disconnected end of a light
guide cable touches operating room drapes or other
flammable materials, fire may result.
Never place the distal end of an illuminated endoscope or
light guide cable on an operating room drape or other
flammable material.
Never direct the light emitted from the endoscope and
light guide cable toward operating room drapes or other
flammable material.
Turn this instrument OFF whenever it is not used.

VIDEO SYSTEM OTV-SI
• Be sure to prepare another video system to avoid that the
examination must be interrupted due to equipment failure or
malfunction.
• Do not allow an endo-therapy accessory or other object to fall
through the ventilation grilles or be placed in the output
connector’s hole. This may result in an electric shock or fire.
• Although the illumination light emitted from the endoscope’s
distal end is required for endoscopic observation and
treatment, inappropriate use may cause damage to living
tissue (e.g., protein denaturation of liver tissue or perforation
of the intestines). Observe the following warnings related to
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 the
endoscope. The automatic brightness control function can
maintain proper illumination.
Do not prolong observation in close proximity to tissue or
keep the distal end of the endoscope in contact with living
tissue.
When discontinuing the use of the endoscope, be sure to
turn this instrument OFF, so that the endoscope does not
irradiate unnecessary light.
• If the message “LAMP IS OVER HEATED” is displayed on
the video monitor during operation of the endoscope,
immediately and carefully withdraw the endoscope from the
patient. The lamp will be extinguished automatically 1 minute
after this message is displayed, the endoscopic image
display will be turned OFF, making it impossible to continue
the operation.
• If the endoscopic image dims during use, blood or mucus
may adhere to the light guide lens 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 temperature at the distal end may rise and
cause mucosal burns. It may also cause patient and/or
operator injury.

Important Information — Please Read Before Use
VIDEO SYSTEM OTV-SI
• Do not touch the light guide plug of the endoscope
immediately after removing it from this instrument or the
output connector of this instrument because they are
extremely hot. Otherwise operator and/or patient injury can
result.
• Do not look directly into the distal end of the endoscope or
the output connector of this instrument while this instrument
is ON. The intense light may cause eye injury.
• This product may interfere with other medical electronic
equipment used in combination with it. Before use, fully
confirm the compatibility of this instrument and all equipment
to be used.
• Be sure to follow the instructions given in the instruction
manuals of the endoscope, electrosurgical unit and
electrosurgery-compatible endo-therapy accessory when
performing high frequency treatment. Otherwise, burns may
result due to abnormal current flow.
• The system should be establish with equipment complied
with relevant EMC standards for safety reason.
• Equipment which do not comply with EMC standard may
cause interference and its function or performance may be
affected.
• Portable or mobile phones may influence the medical
electrical equipment by their emitting energy.
• Do not use a pointed or hard object to press the switches on
the front panel of this instrument. This may break the
switches.
• Do not handle this instrument roughly, as this may result in
equipment damage or patient and operator injury.
• Be sure to observe the following points. Otherwise, a failure
in an electrical contact may result in malfunction.
Do not touch the electrical contacts in the video connector
socket of this instrument.
Do not apply excessive force to the connectors.

Cardiac applications
• Use only the devices listed in the “System chart” (TYPE CF
APPLIED PART) 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 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 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 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 light guide cable and camera head listed in
the “System chart” (TYPE CF APPLIED PART) in the
Appendix as suitable for cardiac applications bear a mark.
• The OLYMPUS 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.
