By setting the clock is automatically adjusted again after a separation from the mains. After 10 minutes, power disconnection, the stored alarms saved radio stations, however, were still present, not more.
The following two (presumable) firmware problems are hopefully eliminated by an update; currently (Oct 2012) is available on the website of Alan Electronics no update available:
1) After turning on a pop-up window (splash screen) with the text "fine tuning ..." that occasionally hangs and does not disappear until a station preset button was pressed appears. Since the DAB + information is displayed (eg. As the currently playing song) only after the closing of the window on the display size and are no longer covered by the window partially, a station key is to use the extended information then press necessary.
2.) Under the menu item Other Settings \ Backlight \ "color bar" is not assumed to select a different background color (as the default black).
