supplemented by the warnings and cautions given in each chapter.
WARNING
• After using this endoscope, reprocess and store it according to the instructions
given in the endoscope’s companion “REPROCESSING MANUAL” with your
endoscope model listed on the cover. Using improperly or incompletely
reprocessed or stored instruments may cause patient cross-contamination and/or
infection.
• Before endoscopy, remove any metallic objects (watch, glasses, necklace, etc.)
from the patient. Performing high-frequency cauterization treatment while the
patient is wearing metallic objects may cause burns on the patient in areas around
the metallic objects.
• Do not strike, hit, or drop the endoscope’s distal end, insertion tube, bending
section, control section, universal cord, or endoscope connector. Also, do not bend,
pull, or twist the endoscope’s distal end, insertion tube, bending section, control
section, universal cord, or endoscope connector with excessive force. The
endoscope may be damaged and could cause patient injury, burns, bleeding,
and/or perforations. It could also cause parts of the endoscope to fall off inside the
patient.
• Never perform angulation control forcibly or abruptly. Never forcefully pull, twist, or
rotate the angulated bending section. Patient injury, bleeding, and/or perforation
may result due to unintended retroflexion of the bending section. It may also
become impossible to straighten the bending section during an examination.
• Never insert or withdraw the endoscope’s insertion section while the bending
section is locked in position. Patient injury, bleeding, and/or perforation may result.
• Never perform flexibility adjustment, operate the bending section, feed air or
perform suction, insert or withdraw the endoscope’s insertion section, or use
EndoTherapy accessories without viewing the endoscopic image or while the
endoscopic image is frozen. Patient injury, bleeding, and/or perforation may result.
• Regardless of the flexibility of the endoscope’s insertion tube, never insert or
withdraw the insertion section abruptly or with excessive force. Patient injury,
bleeding, and/or perforation may result.
• If it is difficult to insert the endoscope, do not forcibly insert the endoscope; stop the
endoscopy. Forcible insertion can result in patient injury, bleeding, and/or
perforation.
• When using the electronic zoom function of the video system center, never insert or
withdraw the endoscope’s insertion section or use EndoTherapy accessories while
the image is magnified. Patient injury, bleeding, and/or perforation can result.

CF-H190L/I OPERATION MANUAL
Page 13
Important Information — Please Read Before Use
WARNING
• Do not touch the light guide on the endoscope connector immediately after
removing it from the light source because it is extremely hot. Operator or patient
burns can result.
• If the endoscopic image becomes dimmer during the procedure, it may indicate that
blood or mucus is adhering to the light guide lens on the distal end of the
endoscope. Immediately withdraw the endoscope from the patient, remove blood
or mucus, and confirm that the light guide lens has no irregularities to use it again.
If you continue to use the endoscope with the obstructed light guide lens, the
temperature at the distal end may rise, which may cause patient injury or operator
and/or patient burns.
• When the endoscopic image does not appear on the monitor, the image sensor
may have been damaged. Turn the video system center OFF immediately.
Continued power supply in such a case will cause the distal end to become hot and
could cause operator and/or patient burns.
• Do not rely on the NBI observation mode alone for primary detection of lesions or to
make a decision regarding any potential diagnostic or therapeutic intervention.
• Be sure to check that the passive bending section bends smoothly by touching it
with your hands before inserting the endoscope into the patient. If any irregularity is
observed on the distal end motion of the endoscope, immediately stop using the
endoscope and withdraw it from the patient. Patient injury, bleeding, and/or
perforation may result.
• When combining the endoscope with a splinting tube, there is a risk of perforation
or bleeding due to entanglement of the mucous membrane, or of the tube
separating from the endoscope and remaining in the body. Before use, be sure to
read the instruction manual for the splinting tube to fully understand its
characteristics.
• During endoscopic treatment, keep the insertion section and the bending section
as straight as possible. If there is a loop or a bend on the insertion section or the
bending section, the operation cannot be performed as intended, and patient injury,
bleeding, and/or perforation can result.
CAUTION
• Do not pull the universal cord during an examination. The endoscope connector will
be pulled out from the output socket of the light source and the endoscopic image
will disappear.
• Do not coil the insertion tube or universal cord with a diameter of less than 12 cm.
Equipment damage may result.
• Do not attempt to bend the endoscope’s insertion section with excessive force
regardless of its flexibility. The insertion section may be damaged.
CF-H190L/I OPERATION MANUAL

connecting or disconnecting the endoscope connector. Failure to do so can result
in equipment damage, including destruction of the image sensor.
• The endoscope’s remote switches cannot be removed from the control section.
Pressing, pulling, or twisting them with excessive force can break the switches
and/or cause water leaks.
• If remote switch 1 does not return to the OFF position after being pressed strongly
from the side, gently pull the switch upwards to return it to the OFF position.
• Do not hit or bend the electrical contacts on the endoscope connector. The
connection to the light source may be impaired and faulty contact can result.
• If endoscope’s suction is insufficient, select another suction system without using
the endoscope and use it according to the directions given in its instruction manual.
Otherwise, a proper endoscopic image may not appear on the monitor.
• Electromagnetic interference may occur on this endoscope near equipment
marked with the following symbol or other portable and mobile RF (Radio
Frequency) communications equipment, such as cellular phones. If
electromagnetic interference occurs, mitigation measures may be necessary, such
as reorienting or relocating this endoscope, or shielding the location.
• To check the electromagnetic interference from other equipment (any equipment
other than this endoscope or the components that constitute this system), the
system should be observed to verify its normal operation in the configuration in
which it will be used.
NOTE
This endoscope contains a memory chip that stores information about the

• Follow the precautions given below. Otherwise, the endoscopic image may
disappear unexpectedly or the frozen image may not be restored during the
examination.
Connect the endoscope connector to the light source completely by pushing the
video connector until it clicks. Otherwise, a faulty contact can result.
Do not bend, hit, pull, or twist the insertion section, bending section, control
section, universal cord, and endoscope connector. The endoscope may be
damaged, and water leaks and/or breakage of internal parts like the cable can
result.
Before connecting the endoscope connector to the light source, confirm that the
endoscope connector, including the electrical contacts, is completely dry and
clean. If the endoscope is used with the electrical contacts wet and/or dirty, the
endoscope and light source may malfunction.
If air bubbles emerge from the endoscope continuously during the leakage test,
do not use the endoscope. Water may enter the endoscope and cause a short
circuit. This may result in image sensor damage.
CAUTION
• Turn the video system center ON only when the endoscope connector is connected
to the light source. In particular, confirm that the video system center is OFF before
connecting or disconnecting the endoscope connector. Failure to do so can result
in equipment damage, including destruction of the image sensor.
• Do not hit or bend the electrical contacts on the endoscope connector. The

Important Information — Please Read Before Use
Examples of inappropriate handling
Details on clinical endoscopic technique are the responsibility of trained specialists. Patient safety in
endoscopic examinations and endoscopic treatment can be ensured through appropriate handling by
the physician and the medical facility. Examples of inappropriate handling are described below.
WARNING
• Over-insufflating the lumen may cause patient pain, injury, bleeding, and/or
perforation.
• Applying suction with the distal end in prolonged contact with the mucosal surface,
with higher suction pressure than required, or with prolonged suction time may
cause bleeding and/or lesions.
• The endoscope has not been designed for use in retroflexed observation in parts of
the body. Performing retroflexed observation in a narrow lumen may make it
impossible to straighten the angle of the bending section and/or withdraw the
endoscope from the patient. Retroflexed observation in parts of the body should be
performed only when its usefulness is determined to be greater than the risk that is
posed to the patient. Also, do not operate the endoscope forcibly in retroflexed
observation.
• Inserting, withdrawing, and using EndoTherapy accessories without a clear
endoscopic image may cause patient injury, burns, bleeding, and/or perforation.
• Inserting or withdrawing the endoscope, feeding air, applying suction, or operating
the bending section without a clear endoscopic image may cause patient injury,
bleeding, and/or perforation.
• For reasons described below, do not rely on the NBI*1 observation mode alone for
primary detection of lesions or to make a decision regarding any potential
diagnostic or therapeutic intervention.
NBI has not been demonstrated to increase the yield or sensitivity of finding any
specific mucosal lesion, including colonic polyps or Barrett’s esophagus.
