6.3 Radio-controlled time reception
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. Changeover from summer time or winter time is auto-
matic. 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 weakened. 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 base 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.
• Open the battery compartment at the back of the base station.
• Insert three new batteries 1,5 V AAA. Make sure the polarities are correct.
