Important Information — Please Read Before Use
LF-TP/DP/GP OPERATION MANUAL
• 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 the light source.
When a light source and a video system are compatible
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 and 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 the light source OFF or activate the light shield
function (standby mode etc.) 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.
• Be sure to prepare another endoscope to avoid that the
examination be interrupted due to equipment failure or
malfunction.
