Interrupt the reception by pressing the WAVE button again, The
DCF symbol disappears. The DCF reception always take place
at 1:00 o’ clock in the morning until 5:00 o’ clock. If the reception
is not successfully received at 5:00 o’ clock, further attempts will
be made again at 1:00 clock in the morning.
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 calendar )
7. 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 1500km.
Changeover from summer time or winter time is automatic. In
Daylight Saving Time “DST” is shown on the LCD. The quality of
the reception depends mainly on the geographic location. Normally
there should be no reception problems within a 1,500 km radius
around Frankfurt.
