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. 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.

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. • 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. • Never use the endoscope unless the single use distal cover is properly attached to the distal end. If the single use distal cover is not attached properly, it may slip off or fall off the distal end during the examination. This could result in thermal injury when the endoscope is used with high-frequency EndoTherapy accessories. Also, continuing the examination with the single use distal cover off may cause patient injury by the uncovered distal end of the endoscope. In addition, if the single use distal cover falls off in the oral cavity, it may cause aspiration or respiratory distress if not promptly identified and removed. • If the single use distal cover should fall off the distal end during the examination, the single use distal cover is seen partly on the endoscopic image. When the single use distal cover should fall off the distal end or seems to fall off, immediately stop the examination, and slowly withdraw the endoscope from the patient. Continuing the examination after the single use distal cover has fallen off may cause patient injury by the uncovered distal end of the endoscope and this could result in thermal injury when the endoscope is used with high-frequency EndoTherapy accessories. In addition, if the single use distal cover falls off in the oral cavity, it may cause aspiration or respiratory distress if not promptly identified and removed. If a single use distal cover falls off inside the patient’s body, stop using the endoscope immediately and retrieve the single use distal cover in an appropriate way.

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 including the objective lens surface. An abnormal endoscopic image and/or water leakage 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. TJF-Q190V OPERATION MANUAL

Important Information - Please Read Before Use

CAUTION • 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. • 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 a 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. • 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. • This endoscope supports radio communication function (receive frequency: 13.56 MHz) that identifies endoscopes. 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.

 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”. Inserting or withdrawing the endoscope, using EndoTherapy accessories, performing suction, feeding air, or performing angulation control under these conditions 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 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.

CAUTION • 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. • 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.

 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. • 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
