Important Information - Please Read Before Use

WARNING • Do not touch the metal plug of the light guide connector immediately after removing it from the video system center 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 and treatment, inappropriate use may cause alteration of living tissues, such as protein denaturation of living tissue and perforation of the intestines. Observe the following warnings on the 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. The automatic brightness control function of the video system center can keep the illumination light properly. Refer to the instruction manual for the video system center for details. − Do not continue observation in close proximity to tissue or keep the distal end of the endoscope in contact with living tissue for a long period of time. Do not touch the distal end of the endoscope. − When discontinuing the use of the endoscope, be sure to turn the video system center OFF or activate its light shield function (standby mode, etc.) so that the endoscope does not emit light 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. A damaged image sensor will display no image and make the distal end hot, which could cause operator and/or patient burns. • 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 use, 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. • If 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.

Important Information - Please Read Before Use

WARNING • Never place the endoscope in contact with lint-free cloths, the surgical drape, or other flammable material when the video system center is turned ON. The heat generated by the light emitted from the distal end of the endoscope may burn the lint-free cloths, drape, or other flammable material. • 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. • When using the electronic zoom function of the video system center, never insert or withdraw the endoscope’s insertion section or use hand instruments while the image is magnified. Patient injury, bleeding, and/or perforation can result. • Insert a hand instrument into the trocar tube close to the endoscope slowly and deliberately. Sudden insertion may damage the bending section and cause parts of the covering to fall off inside the patient. • Do not use the endoscope while using a laser system. The endoscopic image may be disturbed, which may cause patient injury, bleeding, and/or perforation. • Take infection-control measures such as lavage of the colon and use of anti-microbial material before using the endoscope for transanal surgery, and follow the guidelines set by the policies at your institution and the professional society.

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 video system center and the endoscopic image will not be visible. • Do not coil the video cable or universal cord with a diameter of less than 12 cm. Endoscope damage can result. • Do not grasp the universal cord or video cable with the drape using the forceps. A hole may be made on the covering of the cord or cable, and water leakage may occur. • Do not apply shocks to the distal end of the insertion section, in particular 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 a crack or chip of the lens on the distal end cannot be found. In this case, stop using the endoscope and contact Olympus. • Do not press the distal end or bending section of the endoscope against hard surfaces such as a bed to prevent damage to the endoscope.

CAUTION • Never press and/or gather the bending section of the endoscope with hand instruments. Damage to the bending section 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 video connector is connected to the video system center. In particular, confirm that the video system center is OFF before connecting or disconnecting the video 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. • Do not hit or bend the electrical contacts on the video connector. The connection to the video system center may be impaired and faulty contact can result. • When inserting and/or withdrawing the endoscope into/from a trocar tube, move the release lever to its free position (“FREE” direction) and release the joystick to straighten the bending section. Also, when using a trocar tube with a valve, keep the valve open during insertion/withdrawal of the endoscope into/from the trocar tube to prevent damage to the bending section of the endoscope. • Do not pull the insertion section of the endoscope with excessive force while the endoscope is inserted into the trocar tube and the bending section is angulated. The bending section may be damaged. • Insert the insertion section of the endoscope into a trocar tube to be used in advance and push out the bending section from the distal end of the trocar. Confirm the index of insertion length. When observing or treating the patient body, angulate the bending section while the bending section is fully extended from the trocar to prevent damage to the bending section. • Do not withdraw the endoscope from the trocar tube with excessive force to prevent damage to the bending section of the endoscope. Withdraw it carefully and slowly.

 Precautions for 3D endoscopic image CAUTION • Before using the endoscope, follow the precautions given below and confirm that the right-eye and left-eye images are displayed the same. If any difference is observed on the images, the endoscope may malfunction. Using the damaged endoscope may cause eyestrain and inappropriate treatment. − Observe the center of the 3D endoscopic image without the 3D glasses to confirm that the vertical length of two overlapping images is the same. The difference of the horizontal length is not an irregularity. − Observe the 3D endoscopic image with the 3D glasses and close the right-eye and left-eye alternately to confirm that no difference of color and brightness between the right-eye and left-eye images is observed. • Before using the endoscope, touch the target object using a hand instrument while observing the 3D endoscopic image to confirm that a sense of depth is normal. If the actual touch of the hand instrument to the target object is slightly faster than displaying the touch on the monitor, continue to use by understanding this condition or switching 3D mode to 2D mode. Otherwise, inappropriate treatment may result. Also, be sure to confirm that a sense of depth is normal when operator’s standing position is changed during examination because the sense of depth for the 3D image varies depending on the distance between the user and the 3D monitor. • Perform 3D observation within the visible range of the 3D monitor described in the instruction manual for the 3D monitor. Performing 3D observation outside of the visible range may not display the 3D endoscopic image normally. Set another 2D or 3D monitor in the proper position for medical personnel as necessary. • There are differences between individuals in their feelings of eyestrain during 3D observation. If feeling eyestrain, stop 3D observation by switching to 2D observation as soon as possible. Otherwise, eyestrain and inappropriate treatment may result. • Hold the endoscope steadily when observing a target. If the 3D endoscopic image moves too fast or shaky, 3D nausea may result. • Do not repeat changing the view between the 3D endoscopic image and the real object frequently. Eyestrain may result. • Do not switch observation mode between 3D mode and 2D mode frequently. Eyestrain may result.

Important Information - Please Read Before Use

CAUTION • The endoscope has two objective lenses on its distal end. Therefore, even if blood or debris is adhering to only one of them, the normal 3D endoscopic image may not be displayed. In this case, thoroughly remove blood or debris from the objective lens. If the 3D endoscopic image is still not displayed normally, the endoscope may not be malfunctioning properly. Stop using the endoscope and contact Olympus. • Only use the appropriate 3D glasses recommended in the instruction manual for the 3D monitor.

NOTE • When the target object, such as an organ, the shaft of a hand instrument, or mist is near the distal end of the endoscope, the normal 3D endoscopic image may not be displayed. It is recommended to always maintain a suitable distance between the endoscope and the target object. • Observing the center of the 3D endoscopic image is recommended. The periphery image is less visible than the central image, which may cause eyestrain. • When using a visor or an eyewear with the 3D glasses, the 3D endoscopic image may not be seen properly. • When using the electronic zoom function of the video system center with the zoom ratio “× 1.5”, the 2D endoscopic image is displayed to prevent eyestrain. Always set the zoom ratio to “× 1.0” or “× 1.2” when observing the 3D endoscopic image. • Observation modes can be switched between 2D and 3D modes by pressing the “DISPLAY MODE” button on the touch panel of the video system center (OTV-S300). The 2D/3D switch function can also be assigned to a remote switch of the endoscope. For details, refer to the instruction manual for the video system center.
