Digium D70 Sidecar buttons cause phone reboot

I was called in to a local church to help with their system that was hit by a hard power outage about a month ago. Everything seems to be fine except for two things 1) the system is no longer activated but it was before the outage and 2) the Digium D70s reboot if you press any of the speed dial buttons (sidecar). The system was working fine before the outage. Both incoming and outgoing calls are fine and the D40s all work as prescribed. Any advice would be welcome!
