Warnings and cautions
Follow the warnings and cautions given below when handling this instrument.
This information is to be supplemented by the warnings and cautions given in
each chapter.
•
Never perform angulation control, suction control or
insertion/withdrawal of the endoscope’s insertion tube
without viewing the endoscopic image. Patient injury,
bleeding and/or perforation can result.
•
Never insert or withdraw the endoscope’s insertion tube while
the UP/DOWN angulation is locked. Patient injury and/or
equipment damage can result.
•
Although the illumination light emitted from the endoscope’s
distal end is required for endoscopic observation and
treatment, it may also alter living tissues by, for example,
causing protein denaturation of living tissue, or perforation of
the intestines.
Observe the following warnings with regard to illumination.
− Always set the minimum required brightness.
Keep in mind that the brightness of the image on a video
monitor may differ from the actual brightness at the distal
end of the endoscope.
Pay close attention to the brightness level setting of the
light source, particularly when operating the electrical
shutter function of a video system. When using a light
source and video system that are compatible with the light
source’s automatic brightness control function, make sure
to use the function. The automatic brightness control
function can better maintain the illumination light level.
Refer to the instruction manual of the light source and the
video system for further details.
− Do not continue observation in close proximity to tissue or
keep the distal end of the endoscope in contact with living
tissue for a long time.
− When the endoscope will not be used for a long period, be
sure to turn OFF the light source or activate the light
shield function (standby mode, etc.) so that the
endoscope is not illuminated unnecessarily.

Chapter 3 Preparation and Inspection
When a deformed or cracked cylinder plug (Available in
some areas) or BAL plug (Not available in EU) is used, fluid
may come out of the suction cylinder.
If the suction function will not be used in a procedure, the
cylinder plug (MAJ-1940) or BAL plug (MH-192) can be used
to cap the suction cylinder.
Inspection of the forceps/irrigation plug
Inspect the assembled forceps/irrigation plug for deformation or cracks as
described in the forceps/irrigation plug’s instruction manual.
3.4
Attaching accessories to the endoscope
Attaching the suction valve (CYF-5A only)
•
Firmly attach the suction valve to the instrument channel
port. If the suction valve is attached to the endoscope
improperly with gap between the base of the suction valve
and the top of the suction cylinder, suction valve may
detached from the endoscope and may cause patient debris
to leak or spray from the gap.
•
Even if the suction function is not used in a procedure,
securely attach the suction valve to the suction cylinder.
Otherwise, fluid may leak from the suction cylinder.
The suction valve does not require lubrication. Lubricants can
cause swelling of the valves’ seals, which will impair the

Attaching the light source to the endoscope
Light guide cable and light source
1.
•
Only use Olympus light guide cables (WA03202A,
WA03200A, A03200A, A3090, A3091, A3093, A3290,
A3291, A3293) with this endoscope. Other light guide cables
could cause, the control section of the endoscope to
overheat, which could cause operator and/or patient burns.
•
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 necessary for adequate viewing. Whenever
possible, avoid close stationary viewing and do not leave the
distal end of the endoscope close to mucous membranes for
a long time.
•
Refer to the “System chart” in the Appendix to confirm that
these instruments are compatible with the ancillary
equipment being used.
Attach the light guide adapter to the light guide connector on the endoscope
(see Figure 3.6).
