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
