The user of this equipment should be thoroughly trained in the applicable procedure. Furthermore, failure to read and thoroughly understand the contents of this instruction manual may result in serious injury to the patient and/or user. It is essential to follow the instructions contained in this and other manuals which pertain to any equipment and accessories used in conjunction with this equipment. Possible injuries related to endoscopic procedures may include electric shock, explosion, burns, perforation, hemorrhage, etc.

Fai/ure to follow these instructions may also result in damage to and/or malfunction of this equipment.

CAUTION

Federal (USA) law restricts this device to sale by or on the order of a physician,

OLYMPUS·

The Olympus CLV~U20has been designed for endoscopic diagnosis, treatment and photo documentation in conjunction with Olympus endoscopes, accessories and other ancillary equipments. Do not use the instrument for any purpose other than its intended application.

Please read this entire manual carefully before using the instrument. It contains pertinent information on the proper care and handling ofyour videoscope. Although videoscopes by nature are delicate instruments, proper handling and cleaning, as described in this manual, will greatly reduce the need for costly repair and maximize the life of your new instrument.

This manual describes the recommended procedures for preparing and inspecting the equipment prior to use. It does not describe how an actual procedure is to be performed in detail. Nor does it attempt to acquaint a beginner with endoscopic technique and the medical aspects of endoscopy. This instrument should be used only by physicians who have received thorough previous training in the art of endoscopy.

The safety and performance of an endoscopic system depends not only on the endoscope but also on any ancillary equipment used with it. Safety precautions must be exercised when handling electrical equipment to prevent operator/patient shock.

If you have any questions concerning the material contained in this manual or concerning the operation or safety of the equipment, please contact your Olympus representative or the nearest Olympus office.

SAFETY SYMBOLS

Replace the Lamp and Filter-2 following the instructions (Section 9-1 Replacement of Lamps; 9-2 Replacement of Filter-2l.

The lamp and heat sinks are extremely hot immediately after use. Allow sufficient time for them to be cooled before lamp replacement.

1.By use of the mode selector, the instrument serves as a possible and universal light source for OES-fiberscopes, Olympus rigid scopes for EVIS 100 System (instantaneous single-plate color chip system), and for EVIS 200 System (sequencing system).

2.By use of OES system, EVIS 100 system and EVIS 200 system, the insertion position of the scope point can be checked by the transillumination function.

3When using EVIS 100 or EVIS 200 system, by use of the Foot Switch, the anc'illaryequipments can be released.

4. Combined with OES fiberscope, SC16-10 and rigid scope and SC16-10R, the following

	advantages can be offered.
•	Photographs under stable exposure can be taken in short distances.
•	Date is visible in the viewfinder and imprinted on film.

•Remote shutter release using a foot switch frees the endoscopist from finger-tip shutter operation.

•Indicators in the camera'sviewfinder predict exposure level before taking photographs and the exposure level is given when taking photographs.

5.1.5 times the flash output of the maximum illumination intensity of the light source is available.

6.Flat switches and display panel can be easily wiped clean.

7.An emergency lamp turns on instantly if the Xenon lamp burns out, to provide illumination bright enough for endoscope withdrawal. A light on the front panel indicates at a glance if the emergency lamp is not installed, is installed improperly or is burned out, or is lighting instead of the Xenon lamp.

8.Air feeding pressure can be adjusted in three levels.

9.With no scope and even when Xenon lamp illuminates, illumination light automatically dims to prevent dazzling and the air feeding pump simultaneously stops.

10.Combined with function expansion devices (under development), light source can be more functionated.

CD The CLV-U20 light source should be used only in a medical facility under the supervision of a trained physician.

@The light source is designed (floating) to function integrally with insulated patient attachement (endoscopes) to prevent operator/patient shock. Endoscopes and cameras to be used with it should not be grounded in order to prevent shocks which may be caused by leakage current from other electrical apparatus applied to the patient The endoscopist should wear rubber gloves as an added precaution.

®The housing of the light source must be grounded securely and effectively. Do not defect the line cord ground connection.

@) The light source/endoscope combination should never be applied to the heart directly.

@Never install and operate the light source where there is the risk of flammable gases.

@Keep liquids away from all electrical equipment to prevent operator shock and instrument damage. Do not use the light source if spilled fluids have entered the unit.
