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 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. 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.

CF-H190L/I OPERATION MANUAL

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. • 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. • 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. • 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 the endoscope’s insertion section with excessive force regardless of its flexibility. The insertion section may be damaged.

CAUTION • 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. • 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. Pressing, pulling, or twisting them with excessive force can break the switches and/or cause water leaks. • If remote switch 1 does not return to the OFF position after being pressed strongly from the side, gently pull the switch upwards to return it to the OFF position. • 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. • If endoscope’s suction is insufficient, select another suction system without using the endoscope and use it according to the directions given in its instruction manual. Otherwise, a proper endoscopic image may not appear on the monitor. • 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.

• 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-190.

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.

WARNING • Over-insufflating the lumen may cause patient pain, injury, bleeding, and/or perforation. • Applying suction with the distal end 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. 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 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. • 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. • 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
