MAJ-2315 for EVIS EXERA III Duodenovideoscope TJF-Q190V WARNING This quick reference guide is a summary of the steps necessary to properly use your MAJ-2315. Follow the detailed steps

instructed in the latest OPERATION/REPROCESSING MANUAL for TJF-Q190V.

CAUTION Do not apply anti-fogging products, olive oil, or products containing petroleum-based substances (e.g. Vaseline®) to the

distal cover and the endoscope. These products may cause cracks of the distal cover. If a distal cover with cracks is used, it may cause thermal injury due to electric current leaks when high-frequency cauterization treatment is performed.

Reason:The hook of the distal ring is not completely visible within the opening of the distal cover

5. Confirm that the distal cover is free of cracks or deformation. 6. Confirm that there is no adhesion of foreign materials

between the distal end of the endoscope and the distal cover.

7. Confirm that the single use distal cover is not seen on the endoscopic image.

Reason:The single use distal cover is partly on the endoscopic view
