CV-170 INSTRUCTION MANUAL

Important Information - Please Read Before Use

WARNING • In case of video system center failure or malfunction, always keep another video system center ready for use. • Never insert anything into the ventilation grills of the video system center. It can cause an electric shock and/or a fire. • Do not look directly into the distal end of the endoscope, the distal end of the light guide cable, or the output socket of the video system center when they are emitting light. The intense light may cause eye injury. • Do not touch the distal end of the endoscope connector of the endoscope, distal end of the light guide connector of the endoscope, both distal ends of the light guide cable, or output socket of the video system center immediately after disconnecting it from the video system center because they are extremely hot. Operator or patient injury can result. • 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 video monitor may differ from the actual brightness at the distal end of an endoscope. − 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. − When discontinuing the use of the endoscope, extinguish the examination lamp by pushing the lamp button. • This product may interfere with other medical electronic equipment used in combination with it. Before use, refer to “ System chart” on page 307 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. • Since the video system center irradiates strong examination light, the disconnected end of the light guide cable or the distal end of the endoscope becomes very hot. To prevent a fire hazard, do not bring the distal end of the light guide cable or the distal end of the endoscope in contact with a flammable object, such as operating room drapes while the examination lamp is ON. When no examination is performed, be sure to turn the video system center OFF or extinguish the examination lamp by pushing the lamp button.

CV-170 INSTRUCTION MANUAL

Important Information - Please Read Before Use

WARNING • Do not touch the output connector of the video system center. Operator or patient injury can result. • 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. • Use the supplied power cord only. Otherwise, equipment malfunction and/or power cord burns can result. Also, never use it for other equipment. • 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. • 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 lesion including colonic polyps or Barrett’s esophagus. − It has not been demonstrated to aid in differentiating establishing the presence or absence of dysplasia or neoplastic changes within mucosa or mucosal lesions. • 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. • 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. • Electromagnetic interference may occur to the video system center when it is placed near equipment marked with the following symbol or other portable and mobile RF communications equipment such as cellular phones. If radio interference occurs, mitigation measures may be necessary, such as reorienting or relocating the video system center or shielding the location.

CAUTION • Do not allow a foreign object to penetrate the inside of the video connector socket, output socket, and portable memory port. The video system center may malfunction. • 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 by hands. Equipment damage and/or malfunction may result. • 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, video converter, 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. Otherwise, the endoscopic image may not be displayed. • Do not leave the examination lamp ON when an endoscope is connected to the video system center. The examination light reaches the maximum intensity and the endoscope’s distal end becomes hot. In addition, smoke may also be produced if the debris attached to the distal end is heated. • Avoid using the video system center in a dusty environment. This may damage the video system center. • Confirm that there is no dust on the ventilation grills. Clean and vacuum dust from the ventilation grills using a vacuum cleaner, when necessary. Otherwise, the video system center may break down and get damaged from overheating.
