• The DCF reception always takes place hourly between 2:00 and 5:00 o'clock in the morning. If the
reception is not successfully received until 5:00 o'clock, the next receive operation is again at 2:00
o'clock in the morning.
There are four different reception symbols:
flashing
just tower
• If the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance,
etc.),the time can be set manually. The DCF symbol disappears and the clock will then work as a
normal quartz clock.(see: Manual settings).
• If do not need DCF,it can turn off the function.(see:Manual settings).
6.3.1 Note for radio-controlled time DCF
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig.It has a time deviation of less than one second in one million
years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77
(77.5 kHz)and has a transmitting range of approximately 1,500 km.Your radio-controlled clock receives
this signal and converts it to show the precise time. Changeover from summer time or winter time is
automatic. In Daylight Saving Time "DST" is shown on the LCD. The quality of the reception depends
mainly on the geographic location. Normally there should be no reception problems within a 1,500 km
radius around Frankfurt.
