CLV-U20 EVIS LIGHT SOURCE Instructions

Page 3

The Olympus CLV~U20 has 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 of your 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.

3 When using EVIS 100 or EVIS 200 system, by use of the Foot Switch, the anc'illary equipments

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's viewfinder 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.

[Setting of illumination light]

CD Verify that the length of the intensification of the illumination when the camera shutter

release is pressed varies with the distance, by testing with the distal end held at varying

distances (between 5 and 60 mm) from the view object.

@ Ensure that the length of the light emitting time becomes shorter when the sensitivity

switch is altered from +2 to -2 (or 1 to 5). and the distance is held constant.

If using combinations other than the OES fiberscopes and SC16-10, and rigid scopes

and the SC16-10R, images taken at short distances may be overexposed. If this

occurs, turn the filter switch 1 'ON'.
