•
In case of instrument failure or malfunction, always keep another video system center in the room ready for use.
•
Never insert anything into the ventilation grills of the video system center. It can cause an electric shock and/or 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 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. Especially in combination with endoscopes using an electronic shutter function, pay attention to the brightness level setting of the light source. When this instrument 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 properly. Refer to the instruction manual of the light source for details. Do not continue observation in the 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.

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 mark.
•
The Olympus surgical holder for telescope (SH-1) has an electrically isolated arm structure which isolates the endoscope from the ground. This design makes the SH-1 suitable for cardiac applications.
