Suddenly having an issue our ACW 4 - display frequently reads Ver 1.02 and will not accept bills or acknowledge selection. Power cycling restores functionality, but only temporarily. Thought it might be due to extreme cabinet heat, but we've had temps in the 70s lately and it's still going out. Also, experienced an areawide power outage prior to the problem but that may also be just coincidence. Any ideas about what is causing this and how to remedy would be greatly appreciated.
