Clock keeping time when off:
Thanks to forum members in this thread for figuring out solution to this. Battery needs a long charge before it will have enough charge to keep time when off, so turn off auto shutoff and leave it on long enough for internal batt to get a good charge. See this part of the thread below for details

Thanks to forum members in this thread for figuring out solution to this. Battery needs a long charge before it will have enough charge to keep time when off, so turn off auto shutoff and leave it on long enough for internal batt to get a good charge. See this part of the thread below for details
