3. After inserting the batteries, the temperature station will start receiving data from
the transmitter. The outdoor temperature and the signal reception icon should then
be displayed on the temperature station. If this does not happen after 3 minutes,
the batteries will need to be removed from both units and reset from step 1.
4. In order to ensure sufficient 868 MHz transmission however, this should under
good conditions be a distance no more than 100 meters between the final position
of the temperature station and the transmitter (see notes on “Mounting” and “868
MHz Reception”).
5. Once the remote temperature has been received and displayed on the
temperature station, the DCF time (radio controlled time) code reception is
automatically started. This takes typically between 3-5 minutes in good conditions.
DCF 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
