2.5 DCF connection
The DCF receiver serves for fully automatic adjustment and synchronization of time using the
DCF radio signal with a coverage within the diameter of 1500 km around the Germany city
Frankfurt am Main. Comprehensive information about time and date is then transmitted into the
DCF transmitter located in Mainflingen near to Frankfurt. The transmitter transmits long-wave
signals at 77.5 kHz frequency. The DCF receiver guarantees absolutely precise time data with
automatic transition to the summer time.
Generally the DCF receiver is supplied with 10 m long cable, but it can be located also at a
longer distance, in which case it is advisable to connect it via a twisted pair of up to 200 m. Do
not install the receiver close to buildings consisting of metallic steel structures, near to PCs, TV
and radio receivers or in places surrounded with thick walls or into underground or cellar areas.
