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. (see: Manual settings).
6.3 Radio-controlled time reception
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 mil-
lion years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency sig-
nal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Changeover from
summer time or winter time is automatic. In Daylight Saving Time DST is shown on the LCD. 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:
•
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 weak-
ened. 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 under 1 second.
6.4 Inserting of the batteries into the basic station
• The batteries will operate as a backup power source in case of power failure.
• For a permanent backlight and to conserve battery power, use the included supplied power
adapter.
