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 Main-
flingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and
has a transmitting range of approximately 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 prob-
lems within a 1,500 km radius around Frankfurt.
Please take note of the following:
• The recommended distance to any interference sources like
computer monitors or TV sets is at least 1.5 - 2 meters.
• 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 night-time, 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.
5. Getting started
• Insert the battery AA size 1.5 V with the polarity as indicated.
• Your clock is now ready to use.
• After the initial setup, the clock's hands move to 12 o'clock and
will try to receive the radio signal for 3-12 minutes. When the
time code is received, the radio-controlled time will be shown.
The clock receives the signal twice a day (1:00 and 3:00 am).
During the reception the clock's second hand stops at 12 h.
