• The clock will then work as a normal quartz clock. (see Manual setting
of clock and calendar
• The radio-controlled clock receives the signals at 0:00, 3:00, 6:00 and
12.00 o'clock in the morning.
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 fre-
quency signal DCF-77 (77.5 kHz) and has a transmitting range of approxi-
mately 1,500 km. Your radio-controlled clock receives this signal and
converts it to show the precise time. 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 reception problems
within a 1,500 km radius around Frankfurt.
Please take note of the following:
•
Recommended distance to any interfering sources like computer
monitors or TV sets is at least 1.5 - 2 metres.
•
Inside ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please place
the unit close to a window to improve the reception.
•
During nighttime, the atmospheric interference is usually less severe
and reception is possible in most cases. A single daily reception is
adequate to keep the accuracy deviation below 1 second.
