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 from any interfering sources like
computer monitors or TV sets is a minimum of 1.5 - 2 meters.
• Within Ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please
place the unit close to a window.
• During night-time, the atmospheric disturbances are 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 one new battery AA size 1.5 V with the polarity as indi-
cated.
• Your clock is now ready to use.
• After the initial setup, the pointers 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 second hand stops at 12 h.
5.1 REC button
• Manual initialization can be helpful. Press the REC button for
3 seconds. The second hand stops and the clock will scan the
DCF frequency signal.
