
Angulation of the distal end
WARNING
• If the angulation control mechanism or any other part of the system is not
functioning properly, stop the examination immediately. Then carefully withdraw the
endoscope while observing the endoscopic image. If the endoscope cannot be
withdrawn from the patient smoothly, do not attempt to forcibly withdraw. Rather,
withdraw the endoscope carefully. If the endoscope cannot be withdrawn from the
patient, consider removing it through open surgery and take proper measures.
Forcibly withdrawing the endoscope may cause patient injury, bleeding, and/or
perforation. If any irregularities with the endoscope are observed, contact Olympus.
• Operate the UP/DOWN angulation control lever slowly while observing the
endoscopic image. Otherwise, patient injury, bleeding, and/or perforation can
result.

Observation of the endoscopic image
WARNING
• Do not rely on the NBI observation mode alone for primary detection of lesions to
make a decision regarding any potential diagnostic or therapeutic intervention.
• When performing the NBI observation of an oral cavity cut off the extraneous light
as much as possible, such as dimming the room light. Otherwise, the examination
might not be done properly.
• If the endoscopic image seems to be dark in the NBI observation mode, change to
normal observation mode. Otherwise, the examination might not be done properly.
NOTE
The color tone and brightness of the NBI observation mode is different from the
WLI observation mode. Use the NBI observation mode only after fully
understanding its features.
Operate the UP/DOWN angulation control lever slowly to guide the distal end for
insertion and observation.
Refer to the light source’s instruction manual for instructions on how to adjust the
brightness.
