WARNING • Do not use this endoscope for any purpose other than its intended use. 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 due to unintended retroflexion of the bending section. 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 perform flexibility adjustment, operate the bending section, feed air or perform suction, insert or withdraw the endoscope’s insertion section, or use EndoTherapy accessories without viewing the endoscopic image or while the endoscopic image is frozen. Patient injury, bleeding, and/or perforation may result. • Regardless of the flexibility of the endoscope’s insertion tube, never insert or withdraw the insertion section abruptly or with excessive force. 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.

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 magnified. Patient injury, bleeding, and/or perforation can result. • Never insert or withdraw the endoscope’s insertion section while the focus setting is set to the near focus mode. Patient injury, bleeding, and/or perforation can 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. • 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 its obstructed 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. • 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. • The endoscope position detecting unit (UPD-3) is designed only to assist the insertion of the endoscope. Never insert the endoscope into the patient’s body by observing only the endoscope position display on the endoscope position detecting unit. Be sure to observe the endoscopic image and insert the endoscope while confirming the safety. If the endoscope is inserted without observing the endoscopic image, patient injury, bleeding, and/or perforation can result. • The endoscope position detecting unit (UPD-3) generates AC magnetic fields. To prevent critical effects on patients, be sure to adhere to the following:  Never use the endoscope position detecting unit on a patient with a pacemaker. The AC magnetic fields generated by the endoscope position detecting unit may cause malfunction or damage to the pacemaker, exerting critical effects to the cardiac function of the patient.  Never use the endoscope position detecting unit on pregnant women or women observed of being pregnant. Never use the endoscope position detecting unit close to pregnant women or women observed of being pregnant. The effects of the AC magnetic field generated by the endoscope position detecting unit on the unborn baby have not yet been determined.

WARNING • Be sure to check that the passive bending section bends smoothly by touching it with your hands before inserting the endoscope into the patient. If any irregularity is observed on the distal end motion of the endoscope, immediately stop using the endoscope and withdraw it from the patient. Patient injury, bleeding, and/or perforation may result. • When combining the endoscope with a splinting tube, there is a risk of perforation or bleeding due to entanglement of the mucous membrane, or of the tube separating from the endoscope and remaining in the body. Before use, be sure to read the instruction manual for the splinting tube to fully understand its characteristics. • During endoscopic treatment, keep the insertion section and the bending section as straight as possible. If there is a loop or a bend on the insertion section or the bending section, the operation cannot be performed as intended, and 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 regardless of its flexibility. 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 of the endoscope. An abnormal endoscopic image may result. • 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. • 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.
