• The device is ready for use.
6.1 Reception of the DCF frequency signal
• The pointers move to 4.00, 8.00 or 12.00 o'clock.
• The clock will now scan the DCF frequency signal.
• When the time code is received successfully after two minutes, the radio-

Radio-controlled alarm clock
Note for radio-controlled time DCF
The time base for the radio-controlled time is a caesium atomic clock opera-
ted 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 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. The
quality of the reception depends mainly on the geographic location. Normal-
ly there should be no reception problems within a 1,500 km radius around
Frankfurt.
Please take note of the following:
• The recommended distance to any interfering 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, the atmospheric interference is usually less severe
and reception is possible in most cases. A single daily reception is ade-
quate to keep the accuracy deviation under 1 second.
