daylight saving and standard time adjustments.

Radio-controlled alarm clocks automatically synchronize with the DCF77 signal and always
display the exact atomic time – including automatic daylight saving and standard
time adjustments. The DCF77 signal has a range of up to approximately 1,500 km around
Frankfurt am Main. This means they work throughout Germany, Austria, Switzerland, and
large parts of Europe. Outside this zone, they continue to function like high-quality
quartz alarm clocks and can be set manually.

If you own a Kienzle radio-controlled alarm clock and it is within range of the DCF77 signal,
the time will be adjusted automatically via the radio signal. You don't have to do anything –
your clock will always show the correct time. The DCF77 signal has a range of up to
approximately 1,500 km around Frankfurt am Main. This means you can receive the
DCF77 signal throughout Germany, Austria, Switzerland, and large parts of Europe.
