• To reduce the risk of fire or shock hazard, do not expose this
equipment to rain or moisture.
• To reduce the risk of fire or shock hazard, keep this
equipment away from all liquids. Use and store only in
locations which are not exposed to the risk of dripping or
splashing liquids, and do not place any liquid containers on
top of the equipment.
• Do not use this instrument beyond the rated outlets and
wiring, otherwise it may result in fire or an electrical shock.
• Always power the monitor with the voltage specified in this
manual. Supplying a nonspecified voltage to the monitor may
result in fire or an electric shock.
• This product has a fluorescent lamp that contains a small
amount of mercury. It also contains lead in some
components. Disposal of these materials may be regulated in
your community due to environmental considerations. For
disposal or recycling information, please contact your local
authorities or the Electronics Industries Alliance.
• Strictly observe the following precautions for the power cord.
Damaging the power cord may result in fire or an electric
shock:
−When placing the power cord, take care that it is not
crushed in the space between the monitor and a wall,
mobile workstation or a shelf.
−Do not modify or damage the power cord.
−Do not stretch or place a heavy object on the power cord.
−Do not place the power cord near heating equipment or
expose it to excessive heat.
−Always grasp and pull the plug when unplugging the
power cord. Do not pull on the cord itself.
• Be sure to use the supplied AC adapter. Do not use the
supplied AC adapter for powering other devices. The
equipment may fail or the power cord may burn.
• If an irregularity is suspected during use of the instrument,
stop operation of the monitor. Some problems may be
correctable by referring to the following procedure. Damage
or irregularity in the instrument may compromise patient or
operator safety and may result in more severe equipment
damage.

−In case of a loss of the endoscopic image or a frozen
image:
Turn off the monitor, and turn on it again after 10 seconds.
Also turn off the ancillary equipment to be used in
combination with this monitor and turn on it again, as
described in the instruction manuals for the equipment. If
the problem cannot be resolved by the described remedial
action, stop using the monitor and gently withdraw the
videoscope, fiberscope, rigid endoscope or ultrasonic
endoscope from the patient’s body as indicated in the
endoscope’s instruction manual.
−In case other abnormalities:
Immediately stop operation of the monitor, withdraw the
videoscope, fiberscope, rigid endoscope or ultrasonic
endoscope from the patient as indicated in the
endoscope’s manual, and take remedial action as
described in Chapter 10, “Troubleshooting”. If the problem
cannot be resolved by the described remedial action, be
sure to contact Olympus for repair as described in Section
10.2, “Returning the monitor for repair” on page 83.
• When installing this instrument on the mobile workstation or a
trolley with a clamping table, be sure to provide the mobile
workstation or trolley with a toppling/movement prevention
measure. If such a measure is not taken, the mobile
workstation or trolley could move or fall during the procedure,
which could cause patient and/or operator injury.
• Before using high-frequency electrosurgical equipment,
make sure that any signal noise emitted from the equipment
does not affect the observation of the surgical procedures. If
high-frequency electrosurgical equipment is used without
such confirmation, patient injury may result.
• To prepare for unexpected equipment failure, be sure to
prepare spare equipment.
• It is recommended that only Olympus high-frequency
electrosurgical equipment be used with this unit.
Non-Olympus equipment can cause interference on the
monitor display or a loss of the endoscopic image.
• Always establish the system with equipment that complies
with relevant EMC standards for safety reasons. Equipment
which does not comply with EMC standards may cause
interference and its function or performance may be affected.

• To protect its components from excessive heat, the monitor
will turn itself OFF if its internal temperature rises to a level at
which equipment damage could occur. If this happens during
the procedure, immediately stop the examination and gently
withdraw the videoscope, fiberscope, rigid endoscope or
ultrasonic endoscope from the patient as indicated in the
endoscope’s instruction manual, and contact Olympus.
• Always use the power cord and connection cables that were
shipped with the monitor or mobile workstation. Using other
power cords or connection cables may result in an electric
shock or malfunction.
• Always use the monitor cables designated in this instruction
manual. Using non-designated monitor cables may result in
production of monitor noise at a level that may affect the
observation and treatment or loss of observation image.
• This apparatus must be grounded. To ensure safe operation,
the three-pin plug must be inserted only into a standard
three-pin power outlet which is effectively grounded through
normal household wiring.
• Extension cords used with the equipment must be three-core
and be correctly wired to provide connection to the ground.
Incorrectly wired extension cords can be extremely
hazardous.
• The fact that the equipment operates satisfactorily does not
imply that it is grounded, and the installation is not necessary
safe. For your safety, if in any doubt about the effective
grounding of the equipment or power outlet, please consult a
qualified electrician.
• Do not place the AC adapter in area accessible to the
patients. Ensure the patients cannot touch the device, as it
can reach high temperature under continuous use.
• In order to maintain adequate ventilation, do not install or
place this unit in a bookcase, built-in cabinet or any other
confined space. To prevent risk of electric shock or fire
hazard due to overheating, ensure that curtains and any
other materials do not obstruct the ventilation.
• When installing the instrument, reserve a space of 10 cm or
larger between the instrument and any walls or other
equipment. Lack of such a space will interfere with the
monitor’s internal cooling and may lead to malfunction or
equipment damage.

• The LCD screen is manufactured to precise specifications.
Although over 99.99% of the pixels function normally, 0.01%
of the pixels are either missing or constantly lit (red, blue or
green). This is normal and not a cause for concern.
• The liquid crystal protection panel is a specially
manufactured component. Wiping it with a hard cloth, or
rubbing it vigorously will scratch the surface.
• If a still image is displayed for an extended period of time, it
may generate a temporary afterimage (phosphor burn-in).
(However, such images can be removed by displaying
normal video for awhile.)
• The response speed and brightness of liquid crystal varies
with ambient temperatures.
• Some video images may appear blurred on the screen.
• Leaving the unit in a location exposed to high temperature
and humidity for an extended period of time may damage the
LCD screen and cause blurring.
• This monitor may become hot after an extended period of
operation, but this does not indicate a malfunction.
• High-frequency electrosurgical equipment can cause slight
interference on the monitor display.
