I would expect that resetting the microprocessor would also clear the user settings, but they're just as I left them, and when the radio came back on, it was still tuned to the station I had been monitoring last. Also, why would a CPU reset also prevent the power from being turned on altogether, and for such a long time? When my computer crashes, the power stays on, and all that's needed to get it back into action is a simple reboot . My ATS-909X, on the other hand, has crashed occasionally and shut itself off, but hitting the power button turned it right back on; only the clock needed to be reset. But then, I don't understand digital electronics, anyway; I just use these devices and hope for the best..
