Chapter 4 Operation
• The flexibility of the insertion tube of the CF-Q180AL/I and
CF-H180AL/I can be adjusted to less than, equal to or more
than that of the CF-Q160L/I. The range of the flexibility
adjustment of the CF-Q180AL/I and CF-H180AL/I are equal
to that of the CF-Q160AL/I.
The flexibility of the insertion tube of the PCF-Q180AL/I can
be adjusted to less than, equal to or more than that of the
PCF-140L/I. The range of the flexibility adjustment of the
PCF-Q180AL/I is equal to that of the PCF-160AL/I.
The insertion tube of the endoscope should be adjusted to
the appropriate flexibility for each case. Always confirm the
flexibility of the insertion tube by holding the insertion tube
with two hands before inserting it into the patient, and adjust
the flexibility as necessary according to the case, region and
patient's condition during an examination. If you are unsure
of the appropriate flexibility of the insertion tube, set it to the
most-flexible condition. Continuing the examination while the
insertion tube is set to an inappropriate degree of flexibility
may cause patient pain, injury, bleeding and/or perforation
(for endoscopes with flexibility adjustment only).
Set the brightness of the light source to the minimum level
necessary to perform the procedure safely. If the endoscope
is used for a prolonged period at or near maximum light
intensity, vapor may be observed in the endoscopic image.
This is caused by the evaporation of organic material (blood,
moisture in 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 with a lint-free cloth moistened with 70% ethyl
or isopropyl alcohol, reinsert the endoscope and continue the
examination.
