DCF-77 RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which 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 Weather station receives this signal and converts it to show the
precise time in summer or wintertime. The quality of the reception depends greatly on the
geographic location. In normal cases, there should be no reception problems within a 1,500 km
radius around Frankfurt.
Once the outdoor temperature is displayed on the Weather station after initial set-up, the DCF
tower icon in the clock display will start flashing in the upper left corner. This indicates that the
clock has detected that there is a radio signal present and is trying to receive it. When the time
code is received, the DCF tower becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then
please take note of the following:
