Important Information - Please Read Before Use

WARNING • 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. Pay attention to the brightness level setting of the light source, particularly when operating the electrical shutter function of a video system center. 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. 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 the obstructed 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.

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, detach the ultrasound cable from the ultrasound cable connector, 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.

Important Information - Please Read Before Use

WARNING • When using the electronic zoom function of the video system center, never insert or withdraw the endoscope’s insertion section or use EndoTherapy accessories while the image is electronically zoomed. Patient injury, bleeding, and/or perforation can result. • 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. • Before each use or after a change of viewing modes/settings, check to ensure the view observed through the endoscope provides a live image (rather than a stored one) and has the correct image orientation. Otherwise, patient injury, bleeding, and/or perforation can result. • Never tie the elastic opening of both sides of the balloon with a thread. This may cause the balloon to rupture or come off the distal end of the endoscope when inflating it excessively. This can result in patient injury. • Never inflate the balloon to a diameter of more than 20 mm when using the endoscope in the trachea. This could result in suffocation of the patient. • Never withdraw the endoscope while the balloon is still inflated. Otherwise, the balloon may burst or come off the distal end of the endoscope. If the balloon cannot be deflated, insert the channel cleaning brush (BW-400B) into the irrigation port. Using slow, short strokes, carefully feed the brush to remove debris. After that, the balloon can be deflated. • When withdrawing the endoscope, make sure that the balloon is completely deflated, using the ultrasound image and endoscopic field of view. Withdrawing the endoscope while the balloon is inflated could result in patient injury. • If any irregularity in the ultrasound image is observed, turn the endoscopic ultrasound center OFF immediately. Continued ultrasound radiation will cause the distal end to become hot and could cause operator and/or patient burns. • Elastography*1 uses the pulsation of a living body. The intentional pressurization is not necessary. Compression onto the tissue by operating the bending section and inserting or withdrawing the endoscope may cause tissue damage, bleeding, or perforation. *1 Elastography is not available with the diagnostic ultrasound system (Hitachi, Ltd.) ProSound F75 in Canada.

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 irregularities 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 faulty contact can result. • 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.

BF-UC190F OPERATION MANUAL

Important Information - Please Read Before Use

CAUTION • Before inserting the endoscope with an endotracheal tube into the patient, confirm that the insertion section of the endoscope can be inserted to 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. • Be sure that this endoscope is not used adjacent to or stacked with other equipment (other than the components of this endoscope or system) to avoid electromagnetic interference. • Do not touch the electrical contacts in the ultrasound cable connector. Equipment damage can result. • Do not pull, twist, or tightly coil the ultrasound cable. Noise can develop in the ultrasound image. • To prevent unnecessary patient exposure to ultrasound radiation, follow the “as-low-as-reasonably achievable” (ALARA) principle when using Olympus ultrasound equipment. Freeze the image whenever you are not actively viewing the “live” ultrasound image. When the equipment is in the FREEZE mode, no ultrasound energy is emitted.

NOTE • This endoscope contains a memory chip that stores information about the endoscope and communicates this information to the video system center CV-190. • When the endoscope gets strong static electricity, noise may be observed in the endoscopic image. This does not indicate a malfunction. • It is highly desirable that a backup ultrasound cable be available to continue clinical procedures in case of a malfunction.

 Precaution 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, 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 leaks 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 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 breakage of the cable or malfunction of the light guide.

 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.
