The device history records for the sam 300p device and pad-pak were reviewed and this confirmed that all manufacturing and quality checks and test had been successfully completed.The sam 300p passed ¿out qat from heartsine technologies on the (b)(6) 2012.Corrosion was observed on and inside the device, including on track 13 (on_button) of the membrane tail.This had subsequently prevented the device from powering off, as per the reported fault.The corrosion would indicate the device had been subject to adverse storage conditions.Furthermore, multiple 10-minute timeouts were observed in the history log, which had depleted multiple pad-paks, including the returned pad-pak.During investigation the device was witnessed switching on automatically, which was attributed to the failure of the membrane.The faults could not be replicated with a new membrane fitted.This would confirm a failure of the returned membrane.It is the policy of heartsine not to refurbish devices which have been returned from the field, after investigation, therefore this device shall be scrapped and replaced with a sam 350p.
