WARNING
• When using spray-type medical agents, such as lubricant, anesthetic, or alcohol,
use them away from the light source so that the medical agents do not contact the
light source. Medical agents might enter the light source through the ventilation
grills and may cause equipment damage.
• Do not use a humidifier near the light source as condensation might occur, and it
may cause an equipment failure.
• If the endoscopic image seems to be dark in an optical-digital observation mode,
change to the normal observation mode. Otherwise, the examination might not be
performed safely.
NOTE
Set the brightness of the examination light to the minimum necessary to perform
the procedure safely. If the endoscope is used for a prolonged period at or near
maximum light intensity, vapor like smoke may be observed in the endoscopic
image. This is caused by the evaporation of organic material (remaining blood,
moisture of stool etc.) due to heat generated by the light guide near the light guide
lens. If this vapor continues to interfere with the examination, remove the
endoscope, wipe the distal end of the endoscope with a lint-free cloth moistened
with 70% ethyl or isopropyl alcohol, reinsert the endoscope, and continue the
examination.
