no symbol - no reception

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 setting of the clock and the
calendar).
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. Changeover from summer time or winter time is automatic. The
quality of the reception depends mainly on the geographic location. Normally there should
be no no reception problems within a 1,500 km radius around Frankfurt.
