The customer reported that the pt experienced a green blinking light on his power adaptor while being supported by the freedom driver.The pt switched the power adaptor without adverse impact.This alleged failure mode poses a low rick to the pt because it did not prevent the freedom driver from performing its life-sustained functions.In addition, the freedom driver has a redundant power source of onboard batteries.The power adapter will be returned to syncardia for evaluation.The results of the investigation will be provided in a supplemental mdr.
