Important Information - Please Read Before Use
Mobile workstation: The mobile workstation is a special trolley on which this light source is placed and used for endoscopic diagnosis and treatment. Wall mains outlet: The wall mains outlet is a wall AC mains power outlet socket with a terminal used exclusively for grounding. Isolation transformer: The isolation transformer is a safety device that is used to isolate noninsulated equipment with potentially high leakage currents to decrease the possibility of electric shock. Transillumination function: With this function, the distal end of the endoscope emits more intense examination light, which transmits through the body wall tissue of the patient and enables the operator to confirm the position of the distal end from outside the patient’s body, provided that the operating room illumination is low. This function is available only with EVIS videoscopes and a few fiberscopes. High intensity mode: This mode emits brighter illumination light than usual. It is available only with the endoscopes and light guide cables compatible with this mode. Special light observation: This is an observation using specific filtered light (e.g. NBI, PDD). NBI (Narrow Band Imaging) observation: NBI observation mode utilizes an optical filter, which filters the white light spectrum, changing it from a broad band to a narrow band. The filter sets the narrow bands to specific wavelengths within the green and blue spectrum that are within the visible light spectrum. PDD (Photo Dynamic Diagnosis) observation: This is one of the special light observations using the exciting light.

Important Information - Please Read Before Use
Cardiac applications •
Use only the devices listed in the “System chart” in the Appendix for endoscopic observation or treatment of the heart or areas near the heart. Other combinations of equipment may cause ventricular fibrillation or seriously affect the cardiac function of the patient.
•
For cardiac applications, never support the endoscope with a metal surgical arm which is not electrically isolated from the ground. If not isolated, the endoscope will be connected to the ground through the surgical arm and bed, and will conduct unexpected leakage current which may seriously affect the cardiac function of the patient.
•
The use of medical devices not specifically designed for cardiac applications may cause ventricular fibrillation or seriously affect the cardiac function of the patient. As specified by the international standard IEC 60601-1, any applied part used for observation or treatment of the heart or areas near the heart must meet “TYPE CF applied part” requirements for low electrical leakage current. When using endoscopes for endoscopic cardiac applications, the applied part requirements include all devices directly connected to the endoscope, such as the light guide cable, camera head and telescope holder. Each of these devices must individually meet the “TYPE CF applied part” requirements for leakage current limits if they are to be used for cardiac applications.
The OLYMPUS light guide cables and camera heads listed in the “System chart” in the Appendix (TYPE CF applied part) which are suitable for cardiac applications bear a
