stations.
– The radio stations are saved automatically.

Radio-controlled clock
With your built-in radio-controlled clock, you are in possession of an
absolutely precise alarm and meeting clock which is automatically set to the
radio-transmitted time signals of the most precise clock in the world: the
atomic clock of the Physikalisch-Technische Bundesanstalt in Braunschweig
(PTB). This clock is so precise that in 1 million years a deviation of 1 second
can be expected.
Your radio-controlled alarm clock receives “time telegrams” via long wave
77.5 kHz from the time signal transmitter DCF 77, located in Mainflingen
(24 km south-east of Frankfurt/Main). This time signal transmitter has a
range of 1500 km.
The device receives signals from the DCF 77 transmitter free of charge via
the connected DCF 77 antenna wherever long wave reception is sufficient
with, for example, a good portable radio. Your radio-controlled clock often
receives the time telegrams at a considerably larger distance from the trans-
mitter; in such cases the quality of the local reception plays a key role.
The clock’s built-in micro-processor processes the received time telegrams
and controls the quartz clock fully automatically. After the clock is first acti-
vated, the DCF synchronisation is performed immediately and subsequently
every hour on the hour. Depending on the point of reception, synchronisa-
tion can take several minutes. During this process the »

nisation continues running in the background. In addition to the advantages
of precision timekeeping and to-the-second wake-up and alarm signals,
your radio-controlled clock sets itself automatically to winter and daylight
savings’ time.
