A philips product support engineer examined the device and found wear and some deformation of the battery springs, but not to the extent that a shorted condition can occur.The spring separators in the battery compartment are intact.The device was then examined with batteries installed.The springs compressed and only contacted the negative battery terminals.There was no contact of the battery springs (negative end) with the battery cases (which are connected mechanically to the positive terminals of the batteries).Lastly, two aa batteries were installed in the device and a m1644a 5 lead ecg lead set was connected to the device and to a patient simulator.The device was allowed to operate for three hours.During this time, the temperature of the device remained at about 70.0¿ 72.0 fahrenheit.The injury reported by the customer may have been pressure necrosis and not a burn caused by laying on top of the device for several days.Based on the information available and the testing conducted we were unable to replicate the reported problem.The reported problem was not confirmed.
