Chapter 4 Operation
The operator of this instrument must be a physician or medical personnel under
the supervision of a physician and must have received sufficient training in
clinical endoscopic technique. This manual, therefore, does not explain or
discuss clinical endoscopic procedures. It only describes basic operation and
precautions related to the operation of this instrument.
• Anytime you suspect an abnormality in an endoscope
function, stop the examination immediately and slowly
remove the endoscope while viewing the endoscopic image.
Using an endoscope that is not functioning properly may
cause patient injury.
• If the endoscopic image on the video monitor should
unexpectedly disappear or freeze during an examination, and
cannot be restored, turn the video system center OFF and
then ON again. If the image still does not appear, stop the
examination immediately, turn the video system center OFF,
then, without touching the angulation control lever, slowly
withdraw the endoscope from the patient.
• If the angulation control mechanism or any other part of the
system is not functioning properly, stop the procedure
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withdrawn from the patient smoothly, do not attempt to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 it; leave it inside the patient and
immediately contact Olympus. Forcibly withdrawing the
endoscope may cause patient injury.
• The temperature at the distal end of the endoscope may
reach 50

C due to intense endoscopic illumination, and may
cause mucosal burns. Always use the minimum level of
illumination, minimum time and suitable distance necessary
for adequate viewing. Whenever possible, avoid close
stationary viewing and do not leave the distal end of the
endoscope close to the mucous membrane for a long time.
• Whenever possible, do not leave the endoscope illuminated
before and/or after an examination. Continued illumination
will cause the distal end of the endoscope to become hot and
could cause operator and/or patient burns.
