Operation Manual

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 Weather Station 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.

Once the outdoor reception test period is completed, the DCF tower icon
in the clock display will start flashing in the upper center. 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.
• 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.
