The referenced 3dv-190 was not returned to olympus medical systems corp.(omsc) for evaluation, therefore omsc cannot evaluate the 3dv-190.Omsc checked the manufacture history of the 3dv-190, there was no irregularity found.The facility was continuing to use the referenced 3dv-190, therefore the 3dv-190 had no malfunction.The exact cause of the reported event could not be conclusively determined, however there is the possibility of this phenomenon is attributed to the following.A temporary abnormality occurred in the power source of the facility.The plug of the extension cord was incompletely connected to the wall outlet of the facility, then the foreign material or dust and so on adhered between the terminals of the plug.Consequently the short circuit occurred at the plug.Because the power consumption of the instruments which connected to the extension cord exceeded the rating of the extension cord, the extension cord broke.Therefore, there is the possibility of this phenomenon is attributed to the inappropriate handling by the user.Olympus stated the appropriate handling of 3dv-190 and the counter measures against abnormalities in the instruction manual of 3dv-190.There were no further details provided.If significant additional information is received, this report will be supplemented.
