Reprocessing Before the First Use/Reprocessing and Storage After Use

1.5.1

Reprocessing Before the First Use/Reprocessing After Use This product has not been reprocessed. The endoscope and its accessories must be reprocessed for the first time prior to use as per instructions provided in the Reprocessing Manual. After using the endoscope and its accessories, reprocess and store them according to the instructions provided in the Reprocessing Manual.

WARNING

Chapter 1 Precautions

• The entire surface and each channel of the endoscope and the accessories must be reprocessed for the first time prior to use, after any servicing and after any subsequent use as per instructions provided in the Reprocessing Manual, even if the accessories were not used during a procedure. In addition, store this product as per instructions provided in the Reprocessing Manual. Inadequate reprocessing or storage may cause infection. • When using this product for a patient with Creutzfeldt-Jakob disease (especially variant Creutzfeldt-Jakob disease), use it exclusively for a patient with the same disease, or properly discard this product after use. Since the cleaning, disinfection and sterilization methods described in the Reprocessing Manual of this product cannot eliminate the causal agents of Creutzfeldt-Jakob disease, the product could be a source of infection. For the treatment of Creutzfeldt-Jakob disease, refer to local guidelines. • Immediately upon completion of the procedure, it is imperative that pre-cleaning is performed as per instructions provided in the Reprocessing Manual. Otherwise, residual organic debris may begin to dry and solidify and hinder effective removal and reprocessing efficacy, causing infection.

CAUTION • The entire surface and each channel of the endoscope and the accessories must be reprocessed for the first time prior to use, after any servicing and after any subsequent use as per instructions provided in the Reprocessing Manual. In addition, store this product as per instructions provided in the Reprocessing Manual. Inadequate reprocessing or storage may cause equipment damage, or reduce performance. • Do not forcibly twist or bend too sharply the insertion tube of the endoscope. It could damage the endoscope.

1.5.2

Storage After Use Store this product after reprocessing. For details on the reprocessing and storage of the endoscope, refer to the Reprocessing Manual.

Chapter 1 Precautions

1.5.3

Disposal For details on the disposal of the endoscope and accessories, refer to the Reprocessing Manual.

1.6

For Safe Operation Be sure to prepare a spare endoscope against unexpected accidents 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.

1.7

Maintenance

WARNING • Component deterioration or functional degradation of the endoscope 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 or once every 100 cases, whichever comes first. Use of abnormal 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. Take appropriate measures by following “Chapter 6 Troubleshooting.” If the irregularity is still observed after inspection, contact your local FUJIFILM dealer.

1.9

Precautions for Transportation

WARNING • Carry a reprocessed endoscope at a clean state. 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 this product is returned for repair. Be sure to reprocess this product before returning for repair. If a product which is not reprocessed is returned, it can create a risk of infection to users, service personnel or other persons in contact with it.

CAUTION • When transporting a reprocessed endoscope, firmly grasp the control portion and scope connector. If only the LG flexible portion or the boot is grasped, it may damage the endoscope. • 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.

1.10 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.
