Section b5, g1, g2: corrected data.Section h3: additional information.Manufacturer¿s investigation conclusion: the report of a centrimag console smoking during battery exchange was confirmed and reproduced during testing of the returned centrimag primary console (serial number (b)(6).The returned console was evaluated and tested by the service depot.Upon arrival an internal inspection of the console was performed.Upon opening the console, a strong burnt smell persisted, confirming the reported event.A nonapproved battery was observed unplugged from the main printed circuit board (pcb).This battery was not reconnected to the main pcb to prevent further damage to the console's electronic components.A lab owned battery was installed in order to further evaluate the unit.Upon powering the console, it was noticed that the flow was not being displayed.This issue was isolated to the installed main pcb.Due to a lack of replacement main pcbs for the 1st gen primary console, the defective component could not be replaced.The customer was notified and responded that they wanted the console returned unrepaired.Applicable sections of the centrimag primary console service process were performed.The console was then scrapped from the customer's product inventory.It was labeled as defective and not suitable for human use.The root cause of the main pcb being damaged was narrowed down to the nonapproved battery installed in the unit.However, it could not be conclusively determined if the battery caused the issue or if it was caused by an improper connection of the battery to the console during battery replacement.The 1st gen centrimag primary console field battery replacement document describes the steps for properly replacing a primary console internal battery.Reports of similar events will continue to be tracked and monitored.No further information was provided.The manufacturer is closing the file on this event.
