Floodlight Cam Wired Pro - distorted audio after resetting

Evening all. After I have reset my Floodlight Cam Wired Pro I am having issues with setting it up again. The audio that plays to say it is in setup mode is now about 0.25x speed and the pitch of the voice is very low. In addition, the flashing light on top of the unit is flashing at about 0.25x the speed it would normally do. It seems as though the whole unit is working 0.25x what it should be. And after setting up, the video itself is double the speed despite the time along the bottom bar being in normal time. When I look at myself walking around the garden I appear to be walking at twice the speed. This is not simply a connection issue as the distorted setup audio from the speaker happens immediately after reset. I have another Cam Pro out the front without any issue. Thanks
