Important Information - Please Read Before Use

Automatic brightness control: The automatic brightness control automatically adjusts the intensity of the light emitted from the light source so that the endoscopic image will be maintained at constant brightness even if the distance between the distal end of the endoscope and the subject changes. Wash out: Wash out is the inability to see details in the endoscopic image due to excessive brightness. Halation: When light stronger than necessary is received by an image sensor, the recognition level of the image sensor is exceeded and part of the image on the monitor becomes white and bright. Image enhancement: Image enhancement is the image processing technique that electronically sharpens the edges of an image. Shutter: Shutter is the device that changes the exposure time of the image sensor so that the brightness of an image is maintained on the video monitor. B.O.D. (Build on demand): B.O.D. (Build on demand) is a printed circuit board that can extend the functionality of the OTV-S7V when installed. Memory Card: Memory Card is a digital medium used by the PC card unit for the OTV-S7. With this instrument, SmartMedia and xD-Picture Card specified by Olympus can be used as Memory Card.

Important Information - Please Read Before Use

Dangers, warnings and notes Follow the dangers, warnings and notes given below when handling this instrument. This information is to be supplemented by the dangers, warnings and cautions given in each chapter.

•

Strictly adhere to the following precautions. Failure to do so may place the patient and medical personnel in danger of electric shock.  When this equipment is used to examine a patient, do not allow the metal parts of the endoscope or its accessories to touch metal parts of other system components. This instrument is electrically connected to the metal parts of other system components and such contact may cause unintended current flow to the patient.  Keep liquids away from all electrical equipment. If liquid enters the unit, stop the operation of the equipment at once and contact Olympus.  Do not prepare, inspect or use this equipment with wet hands.

•

Never install and/or operate the OTV-S7V in locations where:  The concentration of oxygen is high.  Oxidizing agents such as nitrous oxide (N2O) are present in the atmosphere.  Flammable anesthetics are present in the atmosphere. Otherwise, explosion and/or fire can result.

•

Be sure to prepare another video system center to avoid that the examination must be interrupted due to equipment failure or malfunction.

•

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 using. Observe the following warnings on the illumination.

VISERA VIDEO SYSTEM CENTER OTV-S7V

Important Information - Please Read Before Use

 Always set the minimum required brightness. The brightness of the image on a video monitor may differ from actual brightness at the distal end of endoscope. Especially, operating the electrical shutter function of this instrument, pay attention to the brightness level setting of the light source. When this instrument is used with a light source with the automatic brightness control function, be sure to use the function of the light source. 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 proximity to tissue or keep the distal end of the endoscope in contact with a living tissue for a long time.  When discontinuing the use of the endoscope, be sure to turn the light source OFF or activate the light shield function (standby mode etc.) so that the endoscope does not irradiate unnecessary light. •

This product may interfere with other medical electronic equipment used in combination with it. Before use, fully confirm the compatibility of this instrument with all equipment to be used with it.

•

Do not use this product in any place where it may be subject to strong electromagnetic radiation (for example, in the vicinity of a microwave therapeutic device, MRI, wireless set, short-wave therapeutic device, cellular/portable phone, etc.). This may impair the performance of the product.

•

If the endoscopic image dims during use, this may be a sign that blood or mucus is adhering to the light guide on the distal end of the endoscope. Carefully withdraw the endoscope from patient and remove the blood or mucus in order 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.

Important Information - Please Read Before Use

Cardiac applications •

Use only the devices listed in the “System chart” 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 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 metal endoscopes for endoscopic cardiac applications, the “Applied Part” requirements include all devices directly connected to the endoscope, such as the light guide (LG) 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 LG cables and camera heads listed in the “System chart” (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.
