1.7

For Safe Operation Be sure to prepare a spare endoscope for unexpected events such as the failure of this product. Otherwise, you may not be able to continue the endoscopic procedure. If the spare endoscope is not available, prepare other alternative means such as abdominal surgery. Note  It is highly recommended that spare or back-up equipment be available to complete procedures due to unforeseen circumstances including but not limited to interruption or loss of a clear endoscopic image, equipment failure, etc.  If an endoscopic image is lost or compromised during a therapeutic procedure, immediately stop treatment and withdraw the endotherapy device together with the endoscope. Use back-up equipment to complete the procedure as necessary.

1.8

Maintenance

WARNING  Deterioration or degradation of the endoscope components or its accessories may occur due to factors such as long-term use, procedures, routine handling and repeated reprocessing. Have this product checked by service personnel once every six months. Use of nonfunctional equipment may cause severe harm to patient or end-users. This product should not be subjected to any type of repair or maintenance procedure while it is being clinically used on a patient (or while it is being reprocessed). The more the product is used, the greater the probability of failure of the endoscope and its accessories. Do not use the endoscope that shows any sign of abnormality or irregularity.

1.10 Precautions for Transportation WARNING  Carry a reprocessed endoscope in a clean manner. If personal protective equipment such as gloves is contaminated, the contaminants adhere to the endoscope and it can be a source of infection.  Contact your local FUJIFILM dealer when the endoscope is returned for repair. Be sure to reprocess the endoscope before returning for repair. A returned product which is not reprocessed can create a risk of infection to users, service personnel or other persons in contact with it.

CAUTION

 When transporting a reprocessed endoscope, do not coil the insertion tube or the LG flexible portion of the endoscope with a small diameter. Doing so may cause endoscope failure.  When transporting the endoscope to the outside of the hospital, store the endoscope in a FUJIFILM-specified carrying case. Not doing so may cause product failure.  When transporting the endoscope to the outside of the hospital, make sure that the insertion portion is set to the most flexible condition before storing the endoscope in a FUJIFILM-specified carrying case. Putting the endoscope in the carrying case while the insertion portion is not set to the most flexible condition could damage the endoscope.

1.11 Precautions Against Electric Shock WARNING  Connect the power plug of related equipment to be used to the protective earth receptacle. Not doing so may cause an electric shock.

CAUTION  Do not use related equipment which is not described in this manual. If the endoscope is used in combination with endoscopic accessories connected to other medical devices, it may cause an electric shock due to an increase in patient leakage current.

Chapter 1 Precautions

1.13 General Warnings and Cautions Observe the following cautions when handling this product. Also, there are same cautions in each chapter.

1.13.1 Precautions for Inspection Before Use WARNING  Make sure to inspect the endoscope and accessories before use according to the procedures provided in this manual. Do not use the equipment that shows any signs of abnormality or irregularity. Use of abnormal equipment may lead to misdiagnosis, cause severe harm or inflammation to the patient and/or pose an infection control risk to the patient.  Make sure to check the forceps valve before use. If the inspection result shows any sign of abnormality or irregularity, replace the forceps valve with a new one already reprocessed. Use of an abnormal forceps valve may cause the leakage of body fluid, posing an infection risk.  Turn the up/down and left/right angulation knobs slowly in each direction until they stop. Repeat this operation several times to confirm that the bending section angulates smoothly and correctly. If the endoscope with an abnormal angulation knob is used, the bending section does not return to its neutral position, causing patient injury or making it impossible to withdraw the endoscope from the patient.  If water leaks from the forceps valve or suction valve during the inspection of the suction function, replace the forceps valve with a new reprocessed forceps valve or the suction valve with a reprocessed spare suction valve. A leaking forceps valve or suction valve may cause backflow of body fluid, posing an infection control risk.  If water leaks from the air/water valve during the inspection of the air/water supply function, replace it with a reprocessed spare one. A leaking air/water valve may cause backflow of body fluid, posing an infection control risk.  Turn off the light of the light source before inspecting the objective lens.
