RADIO CONTROLLED TIME:
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 Moonphase wall clock receives this signal and converts it to
show the precise time in summer or winter time.
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.
Once the outdoor temperature is displayed on the Moonphase wall clock, the DCF tower icon in
the clock display will start flashing. This indicates that the clock has detected that there is a radio
signal present and is trying to receive it. 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 metres.
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 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.
TIME ZONE SETTING
After entering the manual setting mode as described above, the time zone can be set between
the 0 to -12 hour and then runs from 12 back to 0 in consecutive 1-hour interval. To do this:
