There's a 9-volt battery cable clearly visible in every photo of the clock.
Many/most plug-in digital alarm clocks use a 9-volt battery to keep time in the event of a power failure, but the battery can't light the display. Some clocks will still sound their scheduled alarm if the battery is connected but AC power is not.
The volatility of this thread is pretty nuts, with posts rapidly alternating between gray and black with every reload, so this will be my only post. I just wanted to point out a common commercial alarm clock design element.
