DCF-77 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 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 1,500km radius
around Frankfurt.
Once the outdoor temperature and humidity are
displayed on the Weather station after initial set-up, the
DCF tower icon in the time display will start flashing in
the upper left corner. This indicates that the weather
station 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
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.
