Important Information - Please Read Before Use

WARNING • Never operate the bending section, perform suction (for CYF-VHA), insert or withdraw the endoscope’s insertion section, or use EndoTherapy accessories without viewing the endoscopic image. Patient injury, bleeding, and/or perforation may result. • Never use EndoTherapy accessories, perform suction (for CYF-VHA), insert or withdraw the insertion section, or perform angulation control while the image is frozen. 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. • 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 light guide 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 endoscope’s distal end 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 by inappropriate using. 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 special attention to the brightness level setting of the light source, particularly when operating the electrical shutter function of a video system center. When both a light source and a video system center have the automatic brightness control function, use the function on the light source. 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. − 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. − 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. • Push the video connector into the video system center until it clicks, then confirm that the video connector is securely attached by pulling it gently. Improper connection will damage the image sensor. The damaged image sensor will display no image and make the distal end hot, which could cause operator and/or patient burns.

Important Information - Please Read Before Use

WARNING • Do not insert the video connector while the electrical contacts are wet and/or dirty. This 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. Carefully withdraw the endoscope from the patient and remove blood or mucus to restore optimum illumination and to ensure the safety of the examination. If you continue to use the endoscope with its obstructed light guide lens, the temperature at the distal end may rise and cause mucosal burns to the patient. It may also cause patient and/or operator injury. • 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.

CAUTION • Do not pull the universal cord and video cable during an examination. The light guide connector will be pulled out from the output socket of the light source and the endoscopic image will not be visible. • Do not coil the insertion tube, universal cord, or video cable with a diameter of less than 10 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 insertion section, particularly the objective lens surface at the distal end. Visual abnormalities 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 leaks. • Do not put or press the video connector and light guide connector on the insertion section when transporting or reprocessing. The insertion section may be damaged.
