The reported complaint was confirmed.The customer reported the lifeband became detached after performing compressions for a duration of 35 minutes.The evaluation of band 1 shows damage indicative of a twisted belt during use.Visual inspection was performed and noted no external damage upon receipt.However, after the white protective sleeve was removed from the band 1, a twisted belt was observed.In addition, unrelated to the reported complaint, one of the hinged belt guards found to be slightly loose and another one does not produce a clicking sound.Functional testing of the lifeband could not be performed because the band 1 had a twisted belt and bent hinge located on the covers/channel braces assembly prevented the belt guards from locking in place.The reported complaint could result from the band 1 twisted belt.During use, the lifeband could exert additional force to one side of the belt and disengage the velcro closure.The autopulse user guides warns the user to not strap across, or otherwise constrain, the lifeband.Constraining the movement of the lifeband can damage or break the lifeband.Additionally, the user guide also provides the following caution - make sure that the lifeband is not twisted before automatic compressions begin.
