WARNING • Never install and operate the video system center in locations where: − The concentration of oxygen is high; − Oxidizing agents (such as nitrous oxide (N2O)) are present in the atmosphere; − Flammable gases are present in the atmosphere; − Flammable liquids are near. Otherwise, an explosion or a fire may result because the video system center is not explosion-proof. • 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 light guide cable or the output socket of the light source 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 biological tissue 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. Be sure to use the automatic brightness control function. This function can keep the illumination light properly. − 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 tapping 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 387 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.

Important Information - Please Read Before Use

WARNING • When turning ON the video system center, never allow the distal end of an endoscope or a light guide cable to come in contact with the patient and/or other flammable materials, such as operating room drapes. Patient injury and/or a fire can result. • If the endoscopic image dims during use, blood, mucus, or debris may have adhered to the light guide cable 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 only the power cord specified by Olympus. Otherwise, equipment malfunction and/or power cord burns may result. Also, never use it for other equipment. Contact Olympus. • 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. • Do not use the video system center when the live image cannot be observed. Otherwise, patient injury may occur. • 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. • 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.
