The reported complaint of the autopulse platform (serial #(b)(4)) power off during compression was confirmed in the archive data but was not confirmed during the functional testing.No malfunction was observed during functional testing.The autopulse platform functioned as intended.Upon visual inspection, no physical damage was observed.A review of the archive data revealed the autopulse platform powered off multiple times due to fault code 29 (loss of brake connectivity) and multiple fault code 28 (loss of clutch connectivity) around the customer's reported event date; thus, confirming the reported complaint.There is a possibility that the power distribution board (pdb) may have intermittent technical problem that were not able to directly identify during testing.As a precautionary measure, the pdb will be replaced to address the reported complaint.The autopulse platform passed initial functional testing without any fault or error.The autopulse platform passed the run-in test multiple times using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries until discharged without any fault or error.Unable to replicate the customer reported problem.Waiting for customer's approval for service repair.
