My 6600 when I did a software upgrade to the current newest version 2.1.32 blinked off and both the radio and Maestro had to be reconnected. I posted this problem in an earlier post but the problem was not able to be duplicated. Just now while sitting at the computer the radio blinked off. The power button gave two flashes of red for a bit and then the radio rebooted on its own. I'm not sure what is going on that I am getting random shutdowns. Thoughts?
