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

Important Information — Please Read Before Use

WARNING

• Never insert or withdraw the endoscope’s insertion section while the focus setting

is set to the near focus mode. Patient injury, bleeding, and/or perforation can result.

• 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.

• The endoscope position detecting unit (UPD-3) is designed only to assist the

insertion of an endoscope. Never insert the endoscope into the patient’s body by

observing only the endoscope position display on the endoscope position detecting

unit. Be sure to observe the endoscopic image and insert the endoscope while

confirming the safety. If the endoscope is inserted without observing the

endoscopic image, patient injury, bleeding, and/or perforation can result.

• The endoscope position detecting unit (UPD-3) generates AC magnetic fields. To

prevent critical effects on patients, be sure to adhere to the following:

 Never use the endoscope position detecting unit on a patient with a pacemaker.

The AC magnetic fields generated by the endoscope position detecting unit may

cause malfunction or damage to the pacemaker, exerting critical effects to the

cardiac function of the patient.

 Never use the endoscope position detecting unit on pregnant women or women

observed of being pregnant. Never use the endoscope position detecting unit

close to pregnant women or women observed of being pregnant. The effects of

the AC magnetic field generated by the endoscope position detecting unit on the

unborn baby have not yet been determined.
