Patient or operator injury and/or equipment damage may result. • 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 distal end, insertion tube, bending section, control section, universal cord, or endoscope connector of the endoscope. Also, do not bend, pull, or twist the distal end, insertion tube, bending section, control section, universal cord, or endoscope connector of the endoscope 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. In addition, the angulation of the endoscope may not return during an examination, and this product may not be pulled out. Take extra caution for the branch of the trachea. • 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.

WARNING • Never insert or withdraw the insertion section abruptly or with excessive force. Patient injury, bleeding, and/or perforation may result. • 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 distal end of the endoscope 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.  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.  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. • 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 before using again. If you continue to use the endoscope with its obstructed or discolored light guide lens, the temperature at the distal end of the endoscope 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 of the endoscope to become hot and could cause operator and/or patient burns.

WARNING • For endoscopes with NBI observation 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. • 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 the distal end of the endoscope 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.

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.

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 endoscope, in particular the objective lens surface at the distal end. An abnormal endoscopic image 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.

CAUTION • 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. • 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. • This endoscope supports radio communication function (receive frequency: 13.56 MHz) that identifies instruments. 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 moving the RF communications equipment away, reorienting or relocating this endoscope, or shielding the location.

• 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.

NOTE • This endoscope contains a memory chip that stores information about the endoscope and communicates this information to the video system center. • 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 of the endoscope 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. • For reasons described below, do not rely on the NBI*1 observation mode (except BF-MP190F) alone for primary detection of lesions or to make a decision regarding any potential diagnostic or therapeutic intervention.  NBI has not been demonstrated to increase the yield or sensitivity of finding any specific mucosal lesion.  NBI has not been demonstrated to aid in differentiating and establishing the presence or absence of dysplasia or neoplastic changes within mucosa or mucosal lesions. *1
