CV-190 PLUS INSTRUCTION MANUAL

Important Information - Please Read Before Use

WARNING • Never insert anything into the ventilation grills of the video system center. It can cause an electric shock and/or a fire. • Although the illumination light emitted from the endoscope’s distal end is required for endoscopic observation and treatment, it may also cause alteration of living tissues such as protein denaturation of liver tissue and biological tissue and perforation of the intestines by inappropriate use. 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 an endoscope. Especially in combination with endoscopes using an electronic shutter function, pay attention to the brightness setting of the light source. When the video system center is used with a light source compatible with automatic brightness control function, be sure to use this function. The automatic brightness control function can keep the illumination light adjusted properly. Refer to the instruction manual for the light source for details. − Do not continue observation in proximity to tissue or keep the distal end of the endoscope in contact with living tissue for a long time. It may cause patient burns. − When discontinuing the use of the endoscope, be sure to turn the light source OFF. • This product may interfere with other medical electronic equipment used in combination with it. Before use, refer to the Appendix to confirm the compatibility of the video system center with all equipment to be used. • Do not use the video system center in any place where it may be subject to strong electromagnetic radiation (for example, in the vicinity of a microwave therapeutic equipment, MRI, wireless set, short-wave therapeutic equipment, cellular/portable phone, etc.). This may impair the performance of the video system center. • If the endoscopic image dims during use, blood, mucus or debris may have adhered to the light guide on the distal end of the endoscope. Carefully withdraw the endoscope from the patient and remove the blood or mucus to obtain optimum illumination and to ensure the safety of the examination. If you continue to use the endoscope in such a condition, the distal end temperature may rise and cause mucosal burns. It may also cause patient and/or operator injury. • Do not rely on the optical-digital observation method alone for primary detection of lesions or for a decision regarding any potential diagnostic or therapeutic intervention.

CV-190 PLUS INSTRUCTION MANUAL

Important Information - Please Read Before Use

WARNING • For reasons described below, do not rely on the NBI observation 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 lesions including colonic polyps or Barrett’s esophagus. • To display endoscopic images, connect the output terminal of the video system center directly to the monitor. Do not make the connection via any ancillary equipment. Images may disappear during observation depending on the condition of the ancillary equipment. • The SDI signal is transmitted by daisy-chaining (chaining in a row) several devices. If one of the devices is turned OFF, the SDI signal is not transmitted to the rest of them.

CAUTION • Do not use a pointed or hard object to press the buttons on the front panel and/or keyboard. This may damage the buttons. • Do not touch the electrical contacts inside the video system center’s connectors. • Do not allow a foreign object to penetrate the inside of the portable memory port or video connector socket. The video system center may be damaged. • Do not simultaneously touch any of the exposed electrical contact pins and the patient. It may pose a risk of an electric shock to the patient and/or user. • Do not apply excessive force to the video system center and/or other instruments connected. Otherwise, damage and/or malfunction can occur. • Do not connect or disconnect the endoscope, videoscope cable, or camera head while the video system center is turned ON. Connecting or disconnecting the endoscope while the video system center is ON may destroy the CCD. Turn the video system center OFF before connecting or disconnecting the endoscope. • Be sure that the video system center is not used adjacent to or stacked with other equipment (other than the components of the video system center or system) to avoid electromagnetic interference.
