Ive been thru a lot of power outages and I know that the SD card corrupts. But this last time the scanner is doing something different. When I turn on the scanner it displays the scanner model / Digital trunking / Dynamic Scanning and thats it!!!!!! It wont do anything else and if i try to turn off the scanner it wont turn off at all. I have to unplug it from the power source and plug it back in to reset it. Does anyone have any ideas of what is going on?
