VISERA XENON LIGHT SOURCE CLV-S40
• 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.
− 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 a
video system, pay attention to the brightness level setting
of this instrument. When this instrument is used with a
video system compatible with the automatic brightness
control function, be sure to use the function of this
instrument. The automatic brightness control function can
keep the illumination light properly. Refer to the instruction
manual of the video system 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 this instrument OFF or activate the light shield
function (standby mode) so that the endoscope does not
irradiate unnecessary light.
• If the endoscopic image dims during use, this may be a sign
that blood or mucus is adhered to the light guide on the distal
end of 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
examination. If you continue to use the endoscope in such a
condition, the distal end temperature may rise and cause
mucosa burns. It may also cause patient and/or operator
injury.
• Do not touch the light guide connector of the endoscope or
the output connector of the light source immediately after
removing it from this instrument because they are extremely
hot. Operator or patient injury can result.
• Do not look directly into the distal end of the endoscope or
the output connector of the light source while the light source
is on. The intense light may harm your eyes.
