Chapter 3 Preparation and inspection before observation
3 Check that there is no dirt or water on the insertion tube distal end.
If dust or water is present, wipe them clean with a soft piece of
gauze or a cotton swab, grasping at hard part of distal end. The
best results may be obtained using the lens cleaning fluid provided
in the lens cleaning kit.
4 Check that the distal end of the insertion tube is not deformed or
loose.
CAUTION
• Never use the distal end of the insertion tube if any part is loose. Otherwise, the loose part
may fall into the inspection object.
• The angulation section is composed of precision parts. Do not pull the distal end of the
insertion tube, do not grasp/bend with a strong force. Otherwise, the parts in the angulation
section may be damaged.
