etc.),
the

The
RCC
reception always takes place hourly between 2:00 and 5:00 o'clock in the morning. If the
recept
ion
is not successfully received until 5:00 o'clock, the next receive operation is again at 2:00
o'clock in the
morn
ing.
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch
Techni
sche
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
trans
mitting range of approximately 1,500 km.Your radio-controlled clock receives
this signal and conve
rts it
to
show the precise time. Changeover from summer time or winter time is
automatic. In Daylight Sav
ing Time
"
D
ST" 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.
