Important Information — Please Read Before Use

•

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.

•

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.

•

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

•

In the event of instrument failure or malfunction, always keep

another Video System in the room ready for use.

•

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.

8

•

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.

•

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.

Chapter 3 Installation and Connection

Chapter 3 Installation and Connection

•

When non-medical electrical ancillary equipment is being

used, connect the Power Cords via an Isolation Transformer

prior to connecting the signal cables. Failure to do this can

cause electric shock, burns and/or fire.

•

Take care not to exceed the rating of the Isolation

Transformer.

•

If the equipment is provided with a ground wire, securely

connect it to an existing GND terminal.

•

Never connect the GND wire to a gas pipe, explosion can

result.

•

When plugging connectors into terminals, hold the connector

plug horizontal to the terminal and push it in completely

without applying excessive force. If the connector is held at

an angle, or undue force is used to connect it, the connector

pins may be deformed.

•

After plugging the connector into the terminal, do not subject

the cable to excessive force.

•

Confirm that the Power Cords are securely attached so they

will not accidentally be disconnected during operation. Never

apply excessive force to bend, pull or twist the Power Cords.

•

Never pull connectors or cables with undue force.

Prepare the instrument and other equipment that are used with this instrument

before each use, according to the “System Chart” in Appendix.

Refer to the instruction manuals for each equipment. Install and connect all

equipment described as follows:
