For better distinctness the LCD screen is split into 4 sections displaying the information for time, date,
indoors and outdoors.
LCD 1 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 Temperature 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 1500km radius of Frankfurt.
Once the outdoor temperature is displayed on the Temperature Station, 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:
