Important Information - Please Read Before Use

•

Although the illumination light emitted from the endoscope’s distal end is required for endoscopic observation and treatment, it may also alter living tissues by, for example, causing protein denaturation of living tissue, or perforation of the bladder or kidney. Observe the following warnings with regard to 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 attention to the brightness level setting of the light source, particularly when operating the electrical shutter function of a video system center. When using a light source and video system center that are compatible with the light source’s automatic brightness control function, make sure to use the function. The automatic brightness control function can better maintain the illumination level. Refer to the instruction manual for the light source and the video system center for further 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 time.  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.

•

Never use EndoTherapy accessories while the image is frozen. Patient injury can result.

•

Do not touch the metal part of the light guide and the light guide connector immediately after removing it from the light source because they are extremely hot.

•

Never insert or withdraw the insertion tube abruptly or with excessive force. Patient injury, bleeding, and/or perforation can result.

•

When the endoscopic image does not appear on the monitor, the CCD 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

•

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 distal end, the temperature at the distal end may rise and cause mucosal burns to the patient. It may also cause patient and/or operator injury.

•

Generally, reprocessing agents1 are aggressive and might affect the distal end of the endoscope. When the effect progresses, fogging of the inner lenses might appear, which results in a foggy video image. Any further use of the endoscope under this condition might lead the lens to come off. Before inserting the endoscope into a patient, make sure that no foggy video image appears, and wipe the outer surface of the lens at the distal end of the endoscope with a soft cloth. In case a foggy image appears, stop using the endoscope immediately.

•

For reasons described below, do not rely on the NBI2 imaging modality alone for primary detection of lesions or to make a decision regarding any potential diagnostic or therapeutic intervention.  It has not been demonstrated to increase the yield or sensitivity of finding any specific mucosal lesion.  It has not been demonstrated to aid in differentiation or establishing the presence or absence of dysplasia or neoplastic changes within mucosa or mucosal lesions.

•

Be sure to prepare another endoscope to avoid that the examination be interrupted due to equipment failure or malfunction.
