WARNING
• Do not touch the light guide on the endoscope connector immediately after
removing it from the light source because it is extremely hot. Operator or patient
burns can result.
• Although the illumination light emitted from the endoscope's distal end is required
for endoscopic observation, it may also cause alteration of living tissues such as
protein denaturation of living tissue and perforation of the tissue through improper
usage. Observe the following warnings for illumination.
 Always set the minimum required brightness. The brightness of the image on a
monitor may differ from the actual brightness at the distal end of the endoscope.
Pay attention to the brightness level setting of the light source, particularly when
operating the electrical shutter function of a video system center. When using a
light source and video system center that are compatible with the light source's
automatic brightness control function, make sure to use the automatic
brightness control function. This function can better maintain the illumination
level. Refer to the instruction manual for the light source and the video system
center for further details.
 Always maintain a suitable distance necessary for adequate viewing while using
the minimum level of illumination for the minimum amount of time. Do not use
close stationary viewing or leave the distal end of the endoscope close to the
mucous membrane for a long time without necessity.
 When the endoscope will not be used for a long period, be sure to turn OFF the
light source or activate the light shield function (standby mode, etc.) so that the
endoscope is not illuminated unnecessarily.
• Do not connect the endoscope connector while the electrical contacts are wet
and/or dirty, which may result in an electric shock, causing severe damage to the
endoscope and compromising patient and/or operator safety.
• If the endoscopic image becomes dimmer during the procedure, it may indicate that
blood or mucus is adhering to the light guide lens on the distal end of the
endoscope or that the light guide lens has been discolored. Immediately withdraw
the endoscope from the patient, remove blood or mucus, and confirm that the light
guide lens has no irregularities to use it again. If you continue to use the endoscope
with its obstructed or discolored light guide lens, the temperature at the distal end
may rise, which may cause patient injury or operator and/or patient burns.
