EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
• The endoscopic image may be disrupted while switching
between WLI observation mode and NBI observation mode.
Therefore, do not perform any endoscopic operation or
treatment while switching between the WLI observation
mode and NBI observation mode. Otherwise, injury in the
body cavity may result.
• 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 70% isopropyl alcohol, reinsert the endoscope, and
continue the examination.
• 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.
