Warnings and cautions
Follow the warnings and cautions given below when handling this endoscope. This information is to be
supplemented by the warnings and cautions given in each chapter.
WARNING
• After using this endoscope, reprocess and store it according to the instructions
given in the endoscope’s companion “REPROCESSING MANUAL” with your
endoscope model listed on the cover. Using improperly or incompletely
reprocessed or stored instruments may cause patient cross-contamination and/or
infection.
• Before endoscopy, remove any metallic objects (watch, glasses, necklace, etc.)
from the patient. Performing high-frequency cauterization treatment while the
patient is wearing metallic objects may cause burns on the patient in areas around
the metallic objects.
• Do not strike, hit, or drop the endoscope’s distal end, insertion tube, bending
section, control section, universal cord, or endoscope connector. Also, do not bend,
pull, or twist the endoscope’s distal end, insertion tube, bending section, control
section, universal cord, or endoscope connector with excessive force. The
endoscope may be damaged and could cause patient injury, burns, bleeding,
and/or perforations. It could also cause parts of the endoscope to fall off inside the
patient.
• Never perform angulation control forcibly or abruptly. Never forcefully pull, twist, or
rotate the angulated bending section. Patient injury, bleeding, and/or perforation
may result. It may also become impossible to straighten the bending section during
an examination.
• Never insert or withdraw the endoscope’s insertion section while the bending
section is locked in position. Patient injury, bleeding, and/or perforation may result.
• Never operate the bending section, perform suction, insert or withdraw the
endoscope’s insertion section, rotate the insertion section, or use EndoTherapy
accessories while no endoscopic image is observed or the endoscopic image is
frozen. Patient injury, bleeding, and/or perforation may result.
• Never insert, withdraw, or rotate the endoscope’s insertion section with excessive
force or while an optimum field of view cannot be obtained. Patient injury, bleeding,
and/or perforation may result. If it is difficult to insert the endoscope, do not forcibly
insert the endoscope; stop the endoscopy. Forcible insertion can result in patient
injury, bleeding, and/or perforation.
• Never insert or withdraw the insertion section abruptly or with excessive force.
Patient injury, bleeding, and/or perforation may result.

Important Information — Please Read Before Use
WARNING
• Do not touch the light guide on the endoscope connector immediately after
removing it from the light source because it is extremely hot. Operator or patient
burns can result.
• Although the illumination light emitted from the endoscope’s distal end is required
for endoscopic observation, it may also cause alteration of living tissues such as
protein denaturation of living tissue and perforation of the tissue through improper
usage. Observe the following warnings for illumination.
Always set the minimum required brightness. The brightness of the image on a
monitor may differ from the actual brightness at the distal end of the endoscope.
When using a light source and video system center that are compatible with the
light source’s automatic brightness control function, make sure to use the
automatic brightness control function. This function can better maintain the
illumination level. Refer to the instruction manual for the light source and the
video system center for further details.
Always maintain a suitable distance necessary for adequate viewing while using
the minimum level of illumination for the minimum amount of time. Do not use
close stationary viewing or leave the distal end of the endoscope close to the
mucous membrane for a long time without necessity.
When the endoscope will not be used for a long period, be sure to turn OFF the
light source or activate the light shield function (standby mode, etc.) so that the
endoscope is not illuminated unnecessarily.
• Do not connect the endoscope connector while the electrical contacts are wet
and/or dirty, which may result in an electric shock, causing severe damage to the
endoscope and compromising patient and/or operator safety.
• If the endoscopic image becomes dimmer during the procedure, it may indicate that
blood or mucus is adhering to the light guide lens on the distal end of the
endoscope or that the light guide lens has been discolored. Immediately withdraw
the endoscope from the patient, remove blood or mucus, and confirm that the light
guide lens has no irregularities to use it again. If you continue to use the endoscope
with its obstructed or discolored light guide lens, the temperature at the distal end
may rise, which may cause patient injury or operator and/or patient burns.
• When the endoscopic image does not appear on the monitor, the image sensor
may have been damaged. Turn the video system center OFF immediately.
Continued power supply in such a case will cause the distal end to become hot and
could cause operator and/or patient burns.
• Do not rely on the NBI observation mode alone for primary detection of lesions or to
make a decision regarding any potential diagnostic or therapeutic intervention.

WARNING
• When performing transnasal insertion with the endoscope, follow the warnings
below.
The shape and size of the nasal cavity and its suitability for transnasal insertion
may vary from patient to patient. No endoscope, including this one, can always
be inserted transnasally into all patients. Before proceeding, always be sure to
confirm that transnasal insertion is possible with the patient by considering both
the size of the patient’s nasal cavity as well as the size of the endoscope’s
insertion section. Patient injury can result or the endoscope could become
lodged and difficult to withdraw.
Transnasal insertion is accompanied by the risk of inflammation of the nasal
cavity. If this happens, the nasal passage will be constricted, making it more
difficult to withdraw the endoscope. In this case, do not use force to withdraw
the endoscope because patient injury, bleeding, and/or perforation may result.
Transnasal insertion is accompanied by the risk of bleeding in the nasal cavity.
Be sure to be prepared to deal with any bleeding. When withdrawing the
endoscope, observe the inside of the nasal cavity to ensure that there is no
bleeding. Even when the endoscope has been withdrawn without bleeding, do
not allow the patient to blow his or her nose strongly because this could cause it
to start bleeding.
Before transnasal insertion, apply the appropriate pretreatment and lubrication
to the patient to enlarge the nasal cavity. Otherwise, patient injury can result or
the endoscope could become lodged and difficult to withdraw. When applying a
pretreatment agent through a tube, insert the tube into the same path as the
path planned for the endoscope’s insertion. Otherwise, the treatment will have
no effect. The effects of the pretreatment agent and lubricant will decrease the
longer the procedure lasts. Apply the pretreatment agent or lubricant as
required during the procedure – for example, when withdrawal seems to be
difficult.
Transnasal insertion of the endoscope should be performed carefully. If
resistance to insertion is felt, or the patient reports pain, stop the insertion
immediately. Patient injury can result or the endoscope could become lodged
and difficult to withdraw.
If it becomes impossible to withdraw the transnasally inserted endoscope, pull
its distal end out of the mouth, cut the flexible tube using wire cutters, and after
ensuring that the cut section will not injure the body cavity or nasal cavity of the
patient, withdraw the endoscope carefully. Therefore, always prepare wire
cutters in advance.
• When using the electronic zoom function of the video system center, never insert or
withdraw the endoscope the endoscope’s insertion section or use EndoTherapy
accessories while the image is electronically zoomed. Patient injury, bleeding,
and/or perforation can result.

BF-290 Series OPERATION MANUAL
Page 15
Important Information — Please Read Before Use
WARNING
• The bending section will only bend to the UP or DOWN direction. To insert or
withdraw, operate the endoscope by considering the direction in which the bending
section is angulated. Never apply excessive force to the RIGHT or LEFT direction
when inserting or withdrawing the endoscope. Patient injury, bleeding, and/or
perforation can result.
CAUTION
• Do not pull the universal cord during an examination. The endoscope connector will
be pulled out from the output socket of the light source and the endoscopic image
will disappear.
• Do not coil the insertion tube or universal cord with a diameter of less than 12 cm.
Equipment damage may result.
• Do not attempt to bend or twist the endoscope’s insertion section with excessive
force. The insertion section may be damaged.
• Do not apply shock to the distal end of the insertion section, in particular the
objective lens surface at the distal end. Visual abnormalities may result.
• If the endoscope is dropped or the distal end of the endoscope receives a hard
impact, the endoscope may be damaged even if no visible damage of the lens on
the distal end can be found. In this case, stop using the endoscope, and contact
Olympus.
• Do not twist or bend the bending section with your hands. Equipment damage may
result.
• Do not squeeze the bending section forcefully. The covering of the bending section
may stretch or break and cause water leakage.
• Do not put or press the endoscope connector on the insertion section when
transporting or reprocessing. The insertion section may be damaged.
• Turn the video system center ON only when the endoscope connector is connected
to the light source. In particular, confirm that the video system center is OFF before
connecting or disconnecting the endoscope connector. Failure to do so can result
in equipment damage, including destruction of the image sensor.
• The endoscope’s remote switches cannot be removed from the control section.
Pressing, pulling, or twisting them with excessive force can break the switches
and/or cause water leakage.
• Do not hit or bend the electrical contacts on the endoscope connector. The
connection to the light source may be impaired and a faulty contact can result.

CAUTION
• Electromagnetic interference may occur on this endoscope near equipment
marked with the following symbol or other portable and mobile RF (Radio
Frequency) communications equipment, such as cellular phones. If
electromagnetic interference occurs, mitigation measures may be necessary, such
as reorienting or relocating this endoscope, or shielding the location.
• When using an endotracheal tube with the endoscope, select the tube that gives a
sufficient gap between the insertion section of the endoscope and itself. A narrow
gap may make it difficult for a patient to breathe and/or damage the endoscope.
• Before inserting the endoscope with an endotracheal tube into the patient, confirm
that the insertion section of the endoscope can be inserted into the endotracheal
tube smoothly by running it back and forth over the entire length of the insertion
section and that the tube does not damage the endoscope. Any protrusions may
damage the bending section cover or strip the external surface of the insertion
section. When using lubrication, make above confirmation before applying
lubrication.
• To check the electromagnetic interference from other equipment (any equipment
other than this endoscope or the components that constitute this system), the
system should be observed to verify its normal operation in the configuration in
which it will be used.
NOTE
• This endoscope contains a memory chip that stores information about the
endoscope and communicates this information to the video system center CV-290.
• When the endoscope gets strong static electricity, noise may be observed in the
endoscopic image. This does not indicate a malfunction.

Precautions for disappeared or frozen endoscopic image
WARNING
• If the endoscopic image disappears unexpectedly or the frozen image cannot be
restored during an examination, immediately stop using the endoscope and
withdraw it from the patient as described in Section 5.3, “Withdrawal of the
endoscope with an irregularity”. Continued use of the endoscope under this
condition could result in patient injury, bleeding, and/or perforation.
• Follow the precautions given below. Otherwise, the endoscopic image may
disappear unexpectedly or the frozen image may not be restored during the
examination.
Connect the endoscope connector to the light source completely by pushing the
endoscope connector until it clicks. Otherwise, a faulty contact can result.
Do not bend, hit, pull, or twist the insertion section, bending section, control
section, universal cord, and endoscope connector. The endoscope may be
damaged, and water leakage and/or breakage of internal parts like the image
sensor cable can result.
Before connecting the endoscope connector to the light source, confirm that the
endoscope connector, including the electrical contacts, is completely dry and
clean. If the endoscope is used with the electrical contacts wet and/or dirty, the
endoscope and light source may malfunction.
If air bubbles emerge from the endoscope continuously during the leakage test,
do not use the endoscope. Water may enter the endoscope and cause a short
circuit. This may result in image sensor damage.
When inserting the endoscope through the mouth, place the mouthpiece
(MA-651) in the patient’s mouth as necessary before inserting the endoscope to
prevent the patient from accidentally biting the insertion section. Biting the
insertion section may result in a break in the cable or malfunction of the light
guide.

Important Information — Please Read Before Use
Examples of inappropriate handling
Details on clinical endoscopic technique are the responsibility of trained specialists. Patient safety in
endoscopic examinations and endoscopic treatment can be ensured through appropriate handling by
the physician and the medical facility. Examples of inappropriate handling are described below.
• Applying suction with the distal end in contact with the mucosal surface, with higher suction
pressure than required or with prolonged suction time may cause bleeding and/or lesions.
• The endoscope has not been designed for use in retroflexed observation. Performing
retroflexed observation in a narrow lumen may make it impossible to straighten the angle of
the bending section and/or withdraw the endoscope from the patient. In case the patient
moves due to coughing and other reasons while the endoscope is angulated in the narrow
lumen, the bending section of the endoscope may be pushed into the lumen and be
retroflexed. Pretreatment to control patient’s coughing reflex and other possible unexpected
moves is the responsibility of trained specialists. Retroflexed observation should be
performed only when the usefulness of doing so is determined to be greater than the risk that
is posed to the patient.
• Inserting, withdrawing, and using EndoTherapy accessories without a clear endoscopic
image may cause patient injury, burns, bleeding, and/or perforation.
• Inserting or withdrawing the endoscope, rotating the insertion section, applying suction, or
operating the bending section without a clear endoscopic image may cause patient injury,
bleeding, and/or perforation.
