radio-controlled clocks in western Europe with
the necessary radio signals. Once the radio-
controlled alarm clock is powered by the battery,
it switches to receiving mode and searches for
the signal from the DCF77 transmitter. If the time
signal has been received with sufficient strength,
the hands set themselves to the correct time.
The radio-controlled alarm clock switches on
several times a day and synchronises the time
with the radio signal from the transmitter DCF77.
In the event the signal is not received, e.g. during
a strong storm, the device continues to run
precisely and then switches to receiving mode
again at the next scheduled time.
