User manual
The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which 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
Moon Phase Clock receives this signal and converts it to show the precise time in summer or
wintertime. The quality of the reception depends greatly on the geographic location. In normal cases,
there should be no reception problems within a 1500km radius of Frankfurt.
When the time code is received, the DCF tower becomes permanently lit and the time will be
displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then
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 meters.
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/ or point its front or
back towards the Frankfurt transmitter.
During nighttime, 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.
