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 Weather 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 1,500 km radius around Frankfurt.
Once the outdoor temperature is displayed on the Weather Clock after initial set-up, the DCF
tower icon in the clock display will start flashing in the upper left corner. 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 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.
