Important Information - Please Read Before Use

WARNING • 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 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. • 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. Forcible insertion can result in patient injury, bleeding, and/or perforation. • 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. • 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. Rotate the single use PowerSpiral tube backward and withdraw the endoscope from the patient, remove blood or mucus, and confirm that the light guide lens has no irregularities for continued use. If you continue to use the endoscope with an 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.

Important Information - Please Read Before Use

WARNING • 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. • Do not use this endoscope without attaching the single use PowerSpiral tube. When the endoscope is inserted into the body cavity without attaching the single use PowerSpiral tube, patient injury, bleeding, and/or perforation may be caused. • The limit function is not intended to guarantee patient safety. The PowerSpiral control unit has a limit function to stop rotation when the motor current exceeds a certain level, which protects the endoscope’s rotation part. It must be noted that the limit function is not intended to guarantee patient safety. The physician should carefully evaluate the clinical factors so that an excessive rotational load will not be applied to the patient’s body cavity. Be sure to examine the following conditions that change a load on the rotation part during inspection mode.  How many level bar indicators are lit.  How the reactive forces felt by the right hand holding the insertion section increase. Based on these kinds of information, decide an allowable rotational load. Do not continue the procedure if such allowable rotational load cannot be determined. Continuing to give an excessive load may cause patient injury, bleeding, and/or perforation in the patient’s body cavity. • Do not forcibly advance, retract, and twist the endoscope regardless of rotation while the single use PowerSpiral tube is in the body cavity, which may result in patient injury, bleeding, and/or perforation. • Do not continue to rotate the single use PowerSpiral tube, if the distal end of the endoscope does not move while the single use PowerSpiral tube is rotating. Continuing to rotate the single use PowerSpiral tube in the same location may result in patient injury, bleeding, and/or perforation. • Do not twist the insertion section of the endoscope when the single use PowerSpiral tube is put under heavy rotational load, which may further increase the rotational load. This may result in patient injury, bleeding, and/or perforation. • Before performing endoscopy or treatment, thoroughly evaluate conditions of the patient. Passage of the single use PowerSpiral tube may result in patient injury, bleeding, and/or perforation depending on a patient’s condition. • When inserting the endoscope, thoroughly observe the inside of the body cavity to evaluate whether it is appropriate to continue the endoscopy. Passage of the single use PowerSpiral tube may result in patient injury, bleeding, and/or perforation.

WARNING • When performing endoscopy in a patient with adhesions and it cannot be confirmed the endoscopy will be performed safely, the procedure must be stopped. However, when its potential benefits are greater than its risk, carefully insert or withdraw by rotating the endoscope through a part of adhesion. Patient and/or adhesion injury, bleeding, and/or perforation may result. • The safety of this endoscopy has not been established in patients with the following conditions. Perform endoscopy and endoscopic treatment in these patients only when its potential benefits are greater than its risks.  Known stricturing diseases such as Crohn’s disease  Any prior abdominal or pelvic surgery including altered anatomy  Pregnancy  Radiation enteritis  History of dysphagia or known esophageal swallowing disorders  Mild to moderate inflammation of colon • If it is assumed that the single use PowerSpiral tube may not be extracted from the patient’s body cavity when the rotation mechanism does not function, then do not use the endoscope for the procedure. Passage of the single use PowerSpiral tube may result in patient injury, bleeding, and/or perforation. • Carefully determine the applicability of a patient with a history of surgery in the gastrointestinal tract. Passage of the single use PowerSpiral tube may result in patient injury, bleeding, and/or perforation. • 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. • Some adverse events due to endoscopic examinations and treatments such as mucosal damage, perforation, mucosal inflammation, bleeding, infection, fever, pain (such as abdominal pain and sore throat), abdominal distention, discomfort (such as abdominal discomfort and swallowing discomfort), digestive dysfunction (such as indigestion, vomiting and nausea), dysphagia (such as odynophagia), respiratory system disorder (such as mediastinal emphysema, respiratory instability, hypoxemia, aspiration pneumonia and cough), hiccup, cardiovascular problem (such as bradycardia, tachycardia, hypotension and hypertension), pancreatitis, hyperamylasemia, hyperlipasemia, intestinal obstruction, intestinal necrosis, intussusception, and parotitis have been reported.

 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.

WARNING • Over-insufflating the lumen may cause patient pain, injury, bleeding, and/or perforation. • Applying suction with the distal end of the endoscope in prolonged 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 in parts of the body other than the stomach. 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. Retroflexed observation in parts of the body other than the stomach should be performed only when its usefulness is determined to be greater than the risk that is posed to the patient. Also, do not operate the endoscope forcibly in retroflexed observation. • Inserting, withdrawing, and using EndoTherapy accessories without a clear endoscopic image may cause patient injury, burns, bleeding, and/or perforation. • Rotating the single use PowerSpiral tube in the direction the endoscope is inserted, inserting or withdrawing the endoscope, feeding air, applying suction, or operating the bending section without a clear endoscopic image may cause patient injury, bleeding, and/or perforation. • When keeping rotating the endoscope forward and the endoscopic image is not clear by positioning the endoscope’s field of view improperly, patient injury, bleeding, and/or perforation may result. • For reasons described below, do not rely on the NBI*1 observation mode 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, including colonic polyps or Barrett’s esophagus. *1
