5. Note for radio-controlled Time DCF
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technis-
che 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. Normally there should be no reception prob-
lems 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 a minimum of 1.5 -
2 metres.
• 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.
6. Getting started
• Insert 1 x AA size 1.5 V alkaline battery as indicated by the polarity.
• The unit is now ready to use.
• After the initial setup, the clock shows 12 o’clock and is trying to receive the radio signal for 5 minutes.
When the time code is received, the radio-controlled time will be shown. If the reception fails, scanning
stops and will be repeated again every solid hour. The reception will be tried 12 times.
• Manual initialization can be helpful. Press
WAVE
or
RESET
button with a pin and the clock will scan the
DCF frequency signal.
7. Manual setting of clock
• In case the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance,
etc.) the time can be set manually. The clock will then work as a normal quartz clock.
• Press the
SET
button with a pin for manual time setting.
• The manually set time will be overwritten by the DCF time when the signal is received successfully.
8. Care and maintenance
• Clean it with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the battery if you do not use the product for a lengthy period.
• Keep the instrument in a dry place.
