Manufacturer Narrative
|
This report is being supplemented to provide additional information, based on the legal manufacturer's re-evaluation of the subject device and findings.There were no significant breakage traces, such as a pit or a defect on the forceps plug hole.And the adhesion of the forceps plug rubber packing was peeled off.Therefore, it is possible, that the stress was applied to the forceps plug hole when the t-shaped tube was detached from the forceps plug hole.Resulting in the rubber packing at the root of the forceps plug being raised and detaching the forceps plug hole.It is likely, that the forceps cap was damaged, so water tightness could not be maintained.Resulting in air leakage.Olympus will continue to monitor field performance for this device.
